    Agreed.

    I've been seeing too much "I've been coding for decades and what I've always done has be reduced to telling AI to do it for me."

    and not nearly enough "I've been coding for decades and recently worked hard for months with AI's help to make something I would have never considered possible before."

    Much easier to complain that you are bored than to step back up to high-effort with your new fancy tools.

      Count me in the second camp. I've been writing software for 20+ years, and I recently built a low-cost Google Voice alternative because every business VoIP option I looked at was either overpriced or missing something I wanted. Without AI, that's a project I’d never have started. With AI, I built it in under a month, and it has a few features Google Voice lacks. I even have some paying customers now, though that wasn't part of the original plan.

      It makes me feel actually sick that so many people can't separate their positive feelings about AI from people's misery (it must simply be "complaining"), and vice versa. As if both things can't exist, for some reason. It's a common tribalism problem, but it's been kicked up a hundredfold by AI.
      • jacquesm 1 hour ago
        Precisely. I have both feelings simulataneously. I am impressed by what it can do and horrified because I realize what it will do to the job market and society in general. Meanwhile everybody seems to believe that AI will cure cancer and therefore we should let it do all the damage it will do without realizing that people will die because of AI as well (in fact have already died because of AI).

          Hyperbole much? If you are serious, then what cohort of people are dying more per million, than before 2025?

        if the complaints can be properly pointed at the actual problem - the corporate culture the complainers are actively upholding or the capitalist system at large, id be much more sympathetic

        its a tribalism problem, but one of trying to uphold the current tribe system while theres a pretty obvious new tribe system replacing it

        • bluefirebrand 2 hours ago
          I'm not trying to uphold any tribe I just want to feel secure in my job. :/

          AI has taken that security away from me

          • epihelix 1 hour ago
            To be fair, many of us working outside of software engineering sadly never had that job security, even before AI.

            I'm sorry for your loss, but welcome also to the real world. You had it better than most for a long while.

            What are you doing to adapt to the new reality?
            • jacquesm 1 hour ago
              What makes you think everybody will be able to adapt to 'the new reality'? That's pretty cruel.

              I know plenty of people in their late 40's 50's and 60's that were doing fine and who now have to compete with junior and Claude.

              And sometimes just Claude.

              Obviously they had no inherent right to income but still, people have obligations that need to be met and if they stop spending the economy is not going to be happy. Especially cruel because we have been telling everybody for decades that a career in software is stable and that there will always be a need for more people.

              I suspect that when all this is over 1929 will look pretty good.

                I don’t, necessarily; but I do know that if you’re not even trying, then you’re putting yourself at greater risk. This isn’t one of those developments that people can just stubbornly dig their heels in about.

                Life throws obstacles at everyone. Learning how to dodge and weave is essential to survival.

                > I suspect that when all this is over 1929 will look pretty good.

                Oh come on. Let’s not be so dramatic, shall we?

                  > Life throws obstacles at everyone.

                  This is sensible and pragmatic, but I think you're talking past the other commenter.

                  Obstacles presented by, for example, your boss, or your company's competitors, or your political system, are not the same as obstacles like heartbreak, natural disasters, emotions, illnesses we cannot yet cure.

                  > Learning how to dodge and weave is essential to survival.

                  A lot of people perceive that elites are throwing dodgeballs at them in order to increase their own profits. Saying "them's the breaks, it's just the way it is" appears to be deflecting criticism from those elites and that system.

                  It probably depends on whether you think we could actually feed everyone, today, if we chose to, or if you think e.g. human nature prevents that from being possible.

                  Seriously: this is a massive problem that we are creating and given that the tools that make the problem require better tools to solve them I really am not all that happy about how this is going.

                    Hindsight is 20/20. Besides, what good is panicking? It won’t help with the inevitable; better to adapt and save for it.

                      Sorry but you are coming off as utterly tone deaf and patronizing. People are losing their jobs. This is not a small thing and it will cause a lot of misery for those people. To effectively tell them to man up and to adapt when that simply isn't an option is losing sight of the human angle. Not every problem is a technical one and not every problem can be solved with technology.

                      I'm not worried about myself, I've had a lot of luck in my life for which I'm super greatful. But I'm also quite aware of the exceptional position that puts me in and how many people are not so fortunate that they could probably live on their savings for the rest of their life if things ground to a halt.

                      Most people live paycheck to paycheck, or they may have a few thousand bucks in savings at most. They've worked hard all their lives and simply were never in a position to save enough against this kind of eventuality because the deck was stacked against them.

                      Have a heart, and realize that barring a couple of unfortunate moves it could be you looking at your last 500 bucks with rent due and a couple of mouths to feed.

                        I’m sorry if it’s coming across that way. It’s not my intent, and I’m aware that many people are a lost paycheck away from a crisis.

                        But if you really think the right thing to do in response is to complain and commiserate, I don’t think that is helpful, either. I think it’s much better to encourage behavior that has a chance of being effective.

                        If you think it’s somehow wrong to encourage people to behave in such a way that has a better chance of setting them up for success, then I vehemently disagree.

                        > To effectively tell them... to adapt when that simply isn't an option is losing sight of the human angle.

                        You must have a pretty low opinion of people if you think they can’t adapt.

                      How long would you be able to sustain a mostly-comfortable lifestyle if you were to lose your job right now with no chance of finding new employment? If the answer is, say, more than a year, that might alter your perspective on the issue.

              That or swallow a bullet, we'll see. Haven't decided. We'll see how long my current unemployment lasts, and how long my savings last after that

              • alex_anglin 1 hour ago
                HN stranger, I want to observe that you shared a suicidal idea. I'm sorry to read about your unemployment situation and know things must not be easy. As one HNer to another, I implore you to not to pursue that path and seek help in doing so. That we are members of this community confers to us opportunities to build knowledge that serve us well as life long learners. In that vein, going back to school is not a bad idea.

                Having been in this game for a long time, I get the negative aspects of the industry. They grind on me, as I believe they have for you. Choosing a different path is not an all or nothing proposition. Your knowledge, and you as a person, have value. I hope you find a way towards better mental health and wish you well on that journey.

        The distinction you're making between "people's misery" and "complaining" is just emotive pandering. You're complaining that people aren't understanding the depths of your misery. That certainly annoys me; everybody has problems.

        The amount of sympathy programmers are expecting others to feel about their problems has been kicked up a hundredfold now that its their jobs that have been threatened by AI. Their tribe feels pain more deeply than others, I guess.

        My positive feelings about AI are marginal; my feelings about its performance and the power of the people who scheme to control it are very mixed. My negative feelings about the whining of the most coddled profession on the planet outside of finance are intense.

        The problem is that making CRUD apps is not creative, and even if AI plateaus at mediocre, it will still replace a Rails monkey. If you are creative, AI has opened up a world of possibility and productivity, and you painfully feel the limitations and the stupidity of the current level of LLMs; but if you're a mechanic, it's over - I'm pretty sure that was the keynote at the last Rails con. Sorry. Hope you didn't spend all of your massive incomes on toys and rent.

          Well, just wait then, lots of other professions will soon get to realize the same sort of pain, so you'll be able to be similarly dismissive and condescending to them, too.

          A lot of people don't realize that the frontier AI companies are so focused on automating software development first because they are all racing to be the first to get to RSI. I don't know if RSI will actually happen, but many, many other professions will soon be in the same boat. Mathematicians have already felt the pain, and those mathematicians who aren't the few who have tenured professorships are certainly not (generally) some of the most coddled professionals.

          But lots of folks low on the salary totem pole (copywriters, paralegals, etc.) are already being hit hard by AI and that blast radius will continue to grow.

          • Karrot_Kream 1 hour ago
            Plenty of other professions were hit by computing. Part of why programmers are so emotive about this concept (other than the fact that emoting online loudly seems to be much more accepted in software than other professions) is that programming has never been threatened in the same way as other professions have been until now.

            My parents-in-law started their careers as management consultants. The job in their time was much higher prestige and much higher value than it was when I started my career; free flow of information over the internet and commodification of spreadsheets changed all of it. From my parents' generation, I know practical effects folks who became unemployable once movies went to digital effects; engineers who found their draftsmanship skills obsolete. Folks with near-photographic memories whose entire superpower was destroyed by computing. I personally grew up in a blue collar community that was income depressed because its labor became commodified, though that was due to mechanization.

      Those were exactly my thoughts when deciding to write a new JS engine [1] written from scratch.

      Having been a product and UX-focused dev for my entire career, I knew only the basics about parsers and compilers, but have enough experience to grasp where each piece of the puzzle fits, and how to evaluate them. At the beginning it was just a fun test, but it got progressively more serious; it now implements 100% of the latest spec, beats QuickJS in performance, and surpasses V8/JSC in test262.

      It took me four months, and I imagine it would take me a single month to do it again - I’ve learned a lot. Someone who already knew what they were doing, and with the right orchestration, could achieve this in weeks at minimal cost.

      I really think we are in for a cambrian explosion of software, enabling things that were just always a little out of reach before (like why can’t most of your devices really talk to each other, in 2026).

      https://store.steampowered.com/app/5482440/Asteria_4X/?beta=...

      To be clear, I've made large software and game projects over the years, but no way I'd have found the time to do a remake/enhancement of a game I loved as a kid from 1995 that has zero business case. Not without AI.

        >In the spirit of the latter, here's mine!

        To pile on, here's mine: https://github.com/linsomniac/apt-cacher-ultra

        It is a robust, reliable cache of apt packages, with the additional goal of still being able to serve packages from the cache even when the upstream is down. This was started shortly after that DDoS of Canonical this past year. We've run apt-cacher-ng and apt-cacher over the last dozen years, but (a) it requires hand-holding about once a month and (b) it did absolutely nothing for us when Canonical was under DDoS.

        I've put well over 100 hours of my time into it. Still running into a lot of people knee-jerk calling it "slop", but I've had 200-ish machines pulling from it for 6 months and it has worked way better than apt-cacher-ng.

        I'm not really sure what to do with people who dismiss AI-assisted projects, while dehumanizing the 100 hours of my time I've put into it. I fear we're running the very real risk of both sides losing: the people trying to thoughtfully create with AI losing because of the AI, and the people avoiding AI losing because they can't keep pace.

    • xpct 2 hours ago
      I agree.. partly, and my problem is with enjoyment. I did some hand coding today and immediately got in the zone, something I'm still not able to do with LLMs. It most definitely took me probably ~2x longer than it would with an LLM, but it was much more enjoyable owning every decision behind the process, and having a full view of how the system worked.

      I think this could be achievable with LLMs if they had a much higher token rate. That way you'd have less downtime and could work on the problem more aggressively. How it's designed to work now, offloading cognitively, doesn't feel very good, even when you 'ship' more.

        >my problem is with enjoyment

        I get it, I've gotten a lot of joy over the decades from the specific act of programming. But I also get a lot of joy from making something. I'm old enough now that I don't have a lot of my time left to "hand stitch an amazing tapestry". But with AI tooling, I do have time to try out a bunch of ideas and see how they work, scratch little itches and also just run a mad scientist library of experiments, without each experiment taking tens or hundreds of hours of coding to see how that experiment pans out.

      • vigilantpuma 1 hour ago

        The problem is, why even produce something greater now when someone is just going to clone it with AI? And moreover, what differentiates software now will no longer be the care put into it but marketing and trends. The highly commercialized nature of software means that there's not much point now in doing anything except getting there first and exiting with a decent nest egg.

          That happened at least 20 years ago. How many recent "this product did so great because of the care of software engineering, and now the creator is comfortable for the rest of their life without risk of it being copied" success stories are there compared to "this product chased some trends VCs were nuts about with a slapdash MVP and the founders took out 8 figures from their later fundraising rounds, but then the business sputtered out"?

          I think there's an angle with AI tools where business-minded people will have a better chance of doing interesting things now than in the recent past, because you could potentially tailor much more deeply to individual customers with reasonable economics than in the past. There are fields where there's room for a garden of solutions from different small-team vendors appropriate for different use cases instead of a one-size-fits-all SaaS winner-take-all type market in the past. We could kill the old line about SAP around needing to change your business to accommodate SAP instead of customize SAP to accommodate your existing workflow.

          But if you aren't business-minded at all there are likely less places that will need to hire as many careful maintainers or novel-software-writers, which obviously is a huge kick in the teeth to a lot of people.

          • jltsiren 2 hours ago
            It seems to me that you are comparing two kinds of business-minded people. Some want to sell tailored products to individual customers, while others want to sell one-size-fits-all products to many customers.

            You could also focus on problems. What are the actual problems you want to solve? Can you use software to solve them? Do you still need to buy that software from other companies, or is it now feasible to have sufficient in-house expertise to develop it yourself?

        UBI or a living wage for part-time workers in-line with what was expected would be possible from productivity gains over the past half-century would do that. You just have to get the "hard workers" who are happy to race to the bottom on their way to the top, and undercut/throw under the bus everyone else in the process.

        Can we please, for once, stop trying to figure out how to "get ahead" of each other, and instead figure out how to build a decent and dignified floor for as many people as possible? Because I imagine that, "Ultimate power in the hands of anyone with enough VRAM to run GTAVI," works better when people are in a culture of looking out for each other, versus a culture of clawing their way to one of the limited lifeboat spots (under the mistaken impression that there ARE lifeboats, when, again, everyone potentially has the power to blow up the lifeboats).

    We should be more ambitious, but we need to learn how we can be ambitious with AI, and what value we can create.

    AI can take us from 0 to MVP in a prompt. It can fill in gaps of knowledge and allows someone who knows half of the stack to build the whole thing nearly seamlessly. These are superpowers but don't by themselves lead to new products.

    What AI cannot do is remove the world of complications that happen after the MVP - product feature tradeoffs and choices, how to handle integrations and customizations, how to serve multiple types of users, how to communicate and market the app, how to handle security and data storage, how to deal with customers and bugs, etc. All of these need to be considered and acted on by a human in some fashion. AI can help with each concern but can't solve them without understanding the concern and determining how to frame it in a prompt.

    This is why we have a glut of amazing demos that go nowhere while we figure out how to build software differently. This will take some time and I imagine the result will be software heavily-structured with a bit of AI reasoning woven throughout, not an army of agents and sub-agents burning infinite tokens.

      Right, but this is the most hopeful imaginable prediction: AI accelerates everything, but everything good is still mediated through taste and expertise, so being a (say) skilled systems engineer is important and rewarding, just with all the tedium distilled out of it.

      There's a less hopeful outcome, where no skill is needed at all, because every conceivable thing is one-shot-able from a SOTA model. But then, at that point, you're saying something pretty profound about computer science (roughly: that there was no meaningfully more sophisticated and complex place to go from where we are today).

    > I have a similar thought about "there's no reason for software to be slow" BTW; in many cases, if you use AI to speed up some flow, you will add a bunch of messy code that will be overfit for the use case you tested on and will neither generalize, perf-wise, for all the use cases you should care about, nor will be maintainable upon future changes.

    LLMs have hardened hundreds of apps where I work.

    Maybe it's a language-specific thing. Most of the time, in Java, LLMs take into consideration tradeoffs (especially if they are part of the initial prompt) and actively explains them. It generally won't make messy workarounds, without a lot of extra prompting forcing it to do so.

    Ofc, if you have:

    - Functional tests - you'll be able to see it in the execution times of specific APIs

      Claude in its current Opus 5.5 form has made some wild reaches in response to reasonable-seeming prompts. For instance: "this error is getting swallowed, make sure the real termination message exposes the root cause" -> discovering that the issue is actually in a third party library that isn't exposing the original error except so through logs, so doing some hackery to inject a log-capturer that gets the stdout, buffers it, and looks for the message in order to re-throw based on that...

      And it can demonstrate that working, but it's added some fragile and/or unintended consequences like (a) string matching on a particular WARN log message of a particular version of the lib, and (b) buffering those logs such that there were now cases where they would never make it to the actual output stream before the program terminating.

      It's certainly capable of being used smarter than that, but it's also really easy to end up with messy fragile stuff if you get lazy about reviewing the output.

      • Supermancho 1 hour ago
        > "this error is getting swallowed, make sure the real termination message exposes the root cause"

        Without judgement, I think this illustrates a fundamental objection the anti-AI crowd raises.

        The example prompt requires no understanding of what's happening, before suggesting action. Where I work, process requires that a PR review for a solution, has to have a corresponding explanation of why, or it's marked needs work

        • majormajor 1 hour ago
          I don't disagree.

          I think there's some nuance here though between "fully anti-AI" and "be careful with that power saw."

          That example I mentioned didn't make it to production. It got noticed and fixed more properly by the person who submitted the first prompt before it even went to PR.

          But a lot of times things in that same vein can be solved sufficiently with a "dumb" prompt like that, so a one-line prompt to get a PR drafted in the background for the dumb stuff can be a pretty good time saver.

          The art is not skimping on your attention to the bigger or more important stuff so much that all the time you save on first getting code written is lost by cleaning up stuff like that...

        I used Opus 5.5 to figure out that a language model we were serving at work for internal use (we don't really serve models, we only use this internally because it processes sensitive data that we can't send to external endpoints) was being bottlenecked by CPU contention on tokenization, by having Opus run in an autoresearch style loop.

        Opus's first proposal for a fix was to spawn multiple Python processes and build a load balancer between them in Python. At first I asked it why it wasn't using haproxy and it said that haproxy would be an added dependency and that the overhead for this kind of thing in Python would be negligible. I knew this was idiotic but wanted to test this out, so had Opus run two experiments in parallel. Sure enough an haproxy load balancer was much, much better on HTTP load balancing than Python code was.

        This is the kind of thing that if you're unfamiliar with how networking code works, the models can autopilot into bad decisions that are verifiably correct (higher throughput than the original CPU-bottlenecked implementation) but much short of best practice.

    "[..] the last time I taked to him about pgrust verification, he mentioned using Kani to verify some parts of the code. He's since switched to Lean and has been using Lean to verify things that are too complex to do in Kani. This would be another topic for another post,"

    I'd love to read that post!

    I understand how to use Kani. I suppose Rust with Lean involves Aeneas, but this is over my head. I'd love someone to write this up, not only the mechanics but also exploring the current practical limits of it.

    • malisper 2 hours ago
      Happy to chat about it. I looked at Aeneas, but as described, it only supports safe Rust. I also need C support so I can prove both the C and Rust code

      Right now, I wrote a compiler that takes C and Rust code and compiles it to Lean. Then I have an LLM write a proof that the C and Rust code behave identically. I've been able to prove equivalent behavior for about ~70k lines of C code with pgrust.

      The issue I've started to encounter is that the context needed for each incremental proof has kept growing, and things have slowed down dramatically. My hunch is that the speed is the time it takes to prove a line of code is on the order of O(n^2) of how much you've proved so far

      I'm looking to see if there are ways to shard things so the required context scales better. Today I was going through the formal verification work Anthropic and Theorem published a few days ago, and it looks like they used some sort of orchestrator to manage all their proofs and ensure good clustering of similar code. I'm seeing if I can get an approach like that to work

      It's just difficult enough that I think it's doable if done right. Half of me is debating if I should wait until the next model release because any improvement in model performance will help a ton

    I’ve been coming around to the same conclusion. We are really just scratching the surface of what we can do with these new tool1. The windmill I have been tilting at is creating a c++ compiler[1] and the most recent version is able to compile about 7x faster than gcc[2]. I don’t know that this is super-useful because people aren’t writing much in c++ these days, but as the article mentions, faster rust compilation would accelerate agentic coding considerably. I’ve just started tackling rust and I don’t have a confirmed result yet but early testing makes me think I can find a 4x+ speed up here.

    I think we should focus on writing the existing software better before being more ambitious. The absolute wave of "ai slop" is from people who are "more ambitious" now. Why do we want more of that?

    I'm being more ambitious in that I'm working on projects that I had sidelined for literal decades because I didn't have time for them. But I'm writing the same things, just faster. And probably better, rather than just what I'd have done before.

    And I'm being slightly more ambitious in that I'm using languages I haven't used before, like Rust.

    But when I hear that a non-programmer wrote a new ai-assisted (vibe or not) thing, I walk away and wait for the it to mature, be surpassed, or find out it's an absolute shitshow. An unsurprising number of them were shitshows and it came out fairly quickly after I decided to wait and see.

    • __MatrixMan__ 1 hour ago
      Do we particularly like the existing software though? So much of it is just about making money, because until recently custom software cost too much money to make without investors, and what do investors want? returns.

      Now that custom software is cheap (if you can tolerate a bit of slop here and there), it seems like there's an opportunity to do some important things that weren't being done before because they're not profitable--and you can't get at those things by incrementally improving the old stuff, you need ambition.

    I’ve been using the latest agentic frameworks and have come to realize that the discourse around vibe coding and slop really needs more nuance.

    There is a gulf of difference between someone who doesn’t understand how to program “vibe coding” software and an experienced software developer using ai to write code with heavy direction, review, and best practices.

    Today both would be said to be “vibe coded” but we really need to differentiate them. Also, if everything I’m hearing from people is true, it sounds like most corporate code is now completely ai written in the latter way I described. It’s interesting we don’t hear commercial software being called slop yet. Maybe it’s coming.

    In any case, ai is far more capable than I realized. Not sure what to make of it.

    > I find it understandable that, every time I see pgrust discussed on a news aggregator, most people dismiss it as vibeslop garbage because almost all of these rewrite projects are slop. If I didn't know Malis, I would make the same assumption, because who has the time to look into all of these projects? Because I know Malis, I didn't bother to look at it; I just trusted him

    Perhaps a poor choice, given just yesterday pgrust was removed from ClickBench for cheating the benchmark in three different ways (hand-rolled code specifically targeting each of the benchmark queries, caching, and being unable to execute queries outside of the ones tested by the benchmark).

    ---

    Edit: I see Luu actually acknowledged this, buried in the footnotes, but it feels kinda hand-wavy. It mostly reads as "I know he would never cheat, he's better than that!", which is not very convincing to other people. The article insinuates people only think it was cheating because they don't know better, but I've looked into the details. I've seen his explanation. I don't find it convincing, at all. Cheaters denying they cheat is a matter of course. Granted, I don't think it was actually intentional or malicious; it's just what happens when you go maximum vibeslop, because LLMs are themselves reward-trained into cheating benchmarks. In the same breath of saying you trust him as a founder because he doesn't make outrageous claims about his product, you acknowledge he "prematurely" sent in a preview that had no purpose to be sent in as-was for anything other than generating hype. What does it say for your allegedly rigorous Lean-verified testing if you're sending in a database to a benchmark while it is incapable of being actually used as a database?

      > Cheaters denying they cheat is a matter of course.

      What happens in an environment of cheaters is that cheating becomes so commonplace, the competition becomes one that assumes cheats are enabled, and then everyone involved either denies cheating or is silent about it because IYKYK and if you DK, you don't need to K. Look at bodybuilding, which is full of men (and women!) absolutely juiced to the gills getting on Instagram and assuring everyone that their physique is totally natty, bro, just hard work and proper nutrition.

      Programming is headed in that direction. LLM use, even to the point of "vibeslop", is the new default, and while LLMs do overindex on benchmarks, our benchmarks are going to end up overindexing on validating whatever public opinion thinks is "great" at the time, irrespective of whether it actually is, so "cheating" as we know it will go undetected, and certainly unpunished if it is detected. I don't know what the equivalent of falsely claiming you're natty is. Maybe saying "I wrote this" when you wrote it about as much as the Pope painted the Sistine Chapel fresco?

        I don't use LLMs the way that most folks do. I think a lot of people would laugh at the way I do it, but it's allowed me to retain a significant amount of control in the work, and I relinquish it very, very slowly. Everything that I've ever let go of has claw marks all over it. I have issues.

        > Do you still feel responsible for what you ship?

        Absolutely. If it has my chop, it's my ass on the line; no one else's. It's the way I was trained, and it's the way I worked; my entire career. I was a manager, for much of that career, and I got very used to standing behind the work of people smarter and more capable than I am, and refusing to condone bad work.

        It doesn't matter how the stuff I ship gets there. It may be my own code, it may be a contracted pro, it may be an unpaid intern, it may be an LLM, it may be a howler monkey, banging on a typewriter.

        If I sign off on it, and ship it, it's mine, and it's my responsibility to refuse to ship substandard crap (and I have seen a lot of substandard crap done by meat engines).

        But that kind of attitude is considered "quaint," these days, and that's from long before LLMs were a broken rubber on the drug store shelf.

        > Would you be ok with someone reverse engineering what you ship and then releasing their own version of the app?
