    The central point, that working with agents is some tried and true variation of existing processes, is incorrect.

    Managing agents has some similarities with EM and program management but a whole lot of other dimensions like token use, avoiding drift, successful concurrency at scale, variations in prompting, testing, evaluation, etc., not to mention that the agents are hyperintelligent coders with zero common sense and a penchant for extremely literal interpretation and ultra-verbosity.

    This isn't an issue for engineers only, it is basically ingrained in the current system in the world. The problem is in simple terms; the fact that being a polymath is absurdly hard in today's world.

    You can't not reinvent something if you don't know it exists in the first place.

    The thing about software is that it slots nicely into every other field, making it a _very_ good base to work off of to get concepts (aka the modern bootleg polymath) that have likely been invented in other fields (with different names).

    This is pretty much the crux of it. It's very similar to the strategy of undercutting a market with VC subsidies until it dies and can be replaced.

      VC subsidies are no longer enough, now we need IPOs to keep it going...

        An IPO and subsequent offers is hardly a temporary subsidy. That can keep going until the economy dies.

    "Suddenly, waterfall is the thing to do."

    Matches my experience. Like 90% of the work is the spec.

    Except instead of weeks researching its like a few hours talking with an agent.

    I'm a hands on engineering leader for a team of about 20 engineers and I've been spending the past 6 months trying to get my team to understand just this.

    On Friday we had a coffee hour to share how we've been working recently and they all seemed perplexed at the workflows I've been adopting. It seems natural to me as someone who's been a manager for some time now, but very alien to all those who've never gone down that path.

    That's not to say my workflows are superior, but they're extremely different to some of my teams now. In reality it's just leaning heavily on things like prds, limiting communication between agents, etc.

    • conradev 6 minutes ago

      In the few instances that I’ve been able to see a total stranger prompt a model, I learn a lot about them.

      The model output is fairly uniform because the models are fairly uniform, but the input is how I understand the prompter’s theory of mind for the LLM.

      The higher fidelity the theory of mind, the more productive the resulting conversation is. Basic things, like knowing what the model is even aware of.

      It’s okay at subjective product judgements with limited context, and so the best engineers make the most important decisions themselves, constraining the model’s solution space to something looking like success.

      Maintaining consistent progress towards a common goal with a bunch of different perspectives is the job.

    • Fordec an hour ago

      Out of curiosity, what was the path that the engineers have been taking? The limiting communication between agents to my mind is obvious to anyone who hasn't swallowed orthodoxy Agile development completely whole. And in my experience the people who have, are rarely the devs. Context switching, between agents, people or whoever, require ramp up time to relearn context. It's always slower and more expensive, other potential upsides about long term training or developers being more replaceable notwithstanding. But no agent gets long term training, not in a 1M context window.

        What? One of the first principles in doing Lean and Agile correctly is limiting Work in Progress and avoiding context switching whenever possible.

          Most organizations are not doing Agile correctly.

          Everywhere I've worked claims to be doing Agile, but none of them have ever done anything to avoid context switching or limiting work in progress

    Relatedly, I fully expect the software business to fail to learn from (nearly) literally every other industry how to operate when your marginal costs are no longer zero. It drives me nuts the number of people in software who think that people in other industries are slow because they’re just not as smart as us, rather than because when it takes months to get a cast part made, it better be right the first time.

    • spicyjpeg 44 minutes ago

      It's even funnier when you realize that not too long ago a decent chunk of the software industry did have to deal with the realities of having to press CDs, print boxes and ship them to retailers in time for the holiday season. The idea that you can ship a half-baked product directly to your end users, charge for it and promise it will get better over time (but only if you manage to secure enough VC funding in the meantime) is a relatively new invention.

        I remember working in the games industry in the 90s and early 2000s; getting a game past Sony testing was so fricking difficult, but it was because once that black disc was cut, there was no way to get an update. You had to be on the money, first release.

    • austin-cheney an hour ago

      Yes, the future of software as an institution, if there is any, is driven by the loudest voices. Those loudest voices are thus driven by selected personalities as opposed to any accomplishment or title. The people who are the highest achievers are rarely the loudest voices as they tend to be the people spending time solving real problems as opposed to the people who just talk about themselves, the forest for the trees.

    • to11mtm an hour ago

      IDK, I think it's been a bit of a (reverse?) bell curve of sorts.

      30+ years ago, You had to be a -lot- more careful about how you handled releasing software. Your stuff was in boxes on shelves, most people didn't have internet access to 'download an update' so fixing anything had a long tail support cost (i.e. paying for the media containing the fix and shipping).

      But there's a fine line. As an example, If your shop is having a vendor do brand new stuff, -compartmentalized from your other stuff-, using technologies that are actually out of support vs an in-support version is a free/zero effort update versus using the outdated stuff... Something went wrong on the management side.

      • BobbyTables2 35 minutes ago

        Exactly!

        How many updates did one apply to Windows 3.0 and Word in those days??

        Sure, there might have been a “hotfix” available for download over a long distance BBS, but virtually nobody would have ever done so (even if they were lucky enough to have a modem). Maybe large companies applied such when impacted.

        Even in the Windows XP days, I think windowsupdate.com was still a manually triggered process…

        For a while, bundled drivers were a steaming pile of crap in quality and several generations of Windows suffered greatly until Microsoft got vendors in line and updates became common.

        > Your stuff was in boxes on shelves...

        Have you ever heard of an SLA? This "used to be" story about software has never been true. If you can't meet the agreement, then or now, you're done.

        Software has always been a lot more diverse than just consumer goods. Why is that your only evidence of how you think software projects are managed?

    • random3 an hour ago

      Yet this is part correct, part wrong. Indeed every industry has some unique challenges that are not directly solvable. However, while a cast is absurdly expensive, the problem is being solved in large part by software in the FDM (3D printing) space and it's changing how things are built.

      edit: this doesn't invalidate the OP thesis, which I strongly agree with. Except that it's not just engineers, this is a more general thing across many fields.

      • collinmcnulty 36 minutes ago

        Do you work in this field or are you just reading that? I’ve been out of the game for over five years now, but as far as I can tell from people I know still in that world, if you’re going to make more than like … 3 of a part, casting is going to be much cheaper. And while you can do some prototyping on 3d prints, the nature of the material winds up different from a cast part.

      • buildsjets 32 minutes ago

        That's totally untrue. You clearly do not have any experience designing, building, manufacturing, testing, and certifying either cast metal or PBF parts. BTW, PBF is powerbed fusion and it is how you make 3D printed metal parts. FDM is a plastic manufacturing process and has nothing at all to do with replacing metal castings.

        For a certain aircraft part that I designed, that measured approximately 16"x8"x10", if you needed up to 12 of them it was cheapest to 3D print them using powerbed fusion from AlSi10Mg, but with a 25% weight penalty due to the lower mechanical properties of 3D printed aluminum compared to cast. If you needed between 12 and 50 of them, it was cheapest to use 3D printing to make a wax preform then use the preform to make a traditional metal investment casting from A356. For more than 50 of them, it was cheapest to invest in permanent closed die tooling.

        Other than for prototyping and extremely low volume production, additive has been a total flop for real-world manufacturing, and has not at all lived up to any of it's lofty promises.

        • __d 21 minutes ago

          Do you see that changing as parts are designed for additive manufacturing? Things that basically cannot be made another way, but have strength, weight, and even functional benefits over a traditionally made part?

          I’m thinking of say cooling channels built into walls of rocket combustion chambers, or car brake/axle assemblies, and some of the „organic“ designs that are lighter and stronger than a cast/machined part.

    • EA-3167 an hour ago

      Absolutely. Engineering is defined by it learning from history, it's an art build up from thousands of years of human attempts to alter the world around them. In a modern sense engineers inevitably require a certain amount of schooling, certification, and most critically of all professional and ethical standards.

    He cites Brooks as proving that communication friction is quadratic in headcount. The exponent does not need to be exactly, or even nearly, 2; 1 + epsilon is already fatal. This is very closely related to Coase's ceiling.

    Solo programming is like managing a team of developers that can only communicate and contribute in one temporal direction.

    Sometimes two or more developers may appear to coexist, but it's actually a simulated concurrency achieved by rapid context switching

    Every time you close a file to open another, you are setting up a different context, therefore you are different agents.

  • mpyne an hour ago

    Man I love and agree with nearly everything about this post except that I wouldn't take the advice to follow waterfall or PMBOK literally.

    The post laments that it's hard to find Dr. Royce's original waterfall paper. That's probably true, I have my copy from a compilation book “Ideas that Created the Future: Classic Papers of Computer Science” edited by Lewis [1].

    I do agree that it's important to do things like scope out your demands of your AI agent, check-in on progress, give as clear a requirement and test cases as you can. But you've always been able to do that with agile methods, and LLMs are fast enough that you don't need to go full waterfall (and if anything it would be counter productive).

    Dr. Royce's paper talks about literally thousands of pages of documentation being needed for any reasonably useful system. Good luck fitting that into even a 1M context window :P.

    But the main point to thesis, that you can't just let your coders loose to do whatever and expect the right results even pre-dates Fred Brooks. I'd argue it goes all the way back to the beginning, to the comments about Baggage's computing machine where British politicians asked if it would generate the correct answers even with incorrect inputs.

    The answer then is the same answer today: of course not, and expecting anything different is foolishness.

    There’s a good list of reasons why we do this, but it leaves out the biggest one, at least for me: building stuff is fun. Reinventing stuff is fun. It’s the most natural hammer to reach for whenever I encounter a nail. Not necessarily the best, but such is life.

  • skydhash an hour ago

    As someone that has studied engineering, designing a solution is very different than managing the resources around the design and implementation of that solution. Books like The Mythical Man Month and Making Things Happen deals with the management side, (from a team level) and The Pragmatic Programmer is from a personal level.

    But TFA is ignoring the actual engineering side where you have to grapple with some primitives and assemble them in a way that do something valuable. And so in a way that is cost effective. That part is always answered by hand waves.

  • nojokepoke 25 minutes ago

    The author missed one key motivation: giant fucking ego. I don’t know why every damn software engineer thinks they are gods gift and can derive anything from first principles. The OP hinted at it with the physicist XKCD but I think it is far more dominant in software because the payouts for mediocrity are just astronomical.

  • slopinthebag an hour ago

    I don’t quite understand the management analogy. Agents aren’t people, they’re code generation machines. Part of managing is delegating and trusting the output of your employees without having to verify everything yourself. But if you’re “managing” an agent, how does that work? You can’t exactly hold an LLM responsible if it fucks something up.

    Or are people really just yoloing and not even verifying that the code generation is correct? I know it’s a bit of a meme, but are people actually doing the meme in irl where there are actual consequences??
