  • Spending your free time building things is super enjoyable …

  • … Anthropic and OpenAI handed out some freebies to hook people to their addictive slot machines.

  • Everything is broken

    • 98% uptime becoming the norm instead of the exception, including for big services.
      • … user interfaces have the weirdest fucking bugs that you’d think a QA team would catch.
        • … seem to be accelerating.
    • … how much code is now being written by AI at Microsoft. … Windows is going down the shitter. Microsoft itself seems to agree …
    • … claiming 100% of their product’s code is now written by AI consistently put out the worst garbage you can imagine.
    • … software companies small and large, saying they have agentically coded themselves into a corner.
  • How we should not work with agents and why

    • … next generation of LLMs will fix it. Pinky promise!
      • … among my circle of peers I have yet to find evidence that this kind of shit works.
    • … clankers aren’t humans.
      • A human makes the same error a few times. Eventually they learn not to make it again.
      • An agent has no such learning ability.
        • It will continue making the same errors over and over again.
    • … requires you to actually observe the agent making that error.
    • … only so many mistakes the human can introduce in a codebase per day.
    • … orchestrated army of agents, … mistakes suddenly compound at a rate that’s unsustainable.
    • … realize … e2e tests you had your clankers write are equally untrustworthy.
      • … only thing that’s still a reliable … is manually testing the product.
        • Congrats, you fucked yourself (and your company).
  • Merchants of learned complexity

    • … agents. … are merchants of complexity.
      • … seen many bad architectural decisions in their training data and throughout their RL training.

        • Guess what the result is?
  • Agentic search has low recall

    • … agents can also no longer deal with it. … codebase and complexity are too big, and they only ever have a local view of the mess.
  • How we should work with agents (for now, I think)

    • … scoped so the agent doesn’t need to understand the full system.
    • … loop can be closed, that is, the agent has a way to evaluate its own work.
    • … output isn’t mission critical
    • … rubber duck to bounce ideas against …
      • … compressed wisdom of the internet and synthetic training
    • … provided that you as the human are the final quality gate.
    • Karpathy’s auto-research … will happily ignore any metrics not captured by the evaluation function, …
      • code quality,
      • complexity,
      • correctness,
    • … let the agent do …
      • boring stuff,
      • stuff that won’t teach you anything new,
      • try out different things you’d otherwise not have time for.
        • … evaluate what it came up with, take the ideas that are actually reasonable and correct, …
    • … slowing the fuck down is the way to go.
      • Give yourself time to think about …
        • … what you’re actually building and why.
        • Give yourself an opportunity to say, fuck no, we don’t need this.
        • Set yourself limits on how much code you let the clanker generate per day,
          • in line with your ability to actually review the code.
    • … architecture, API, and so on, write it by hand.
      • Be in the code.
        • … write the thing or seeing it being built up step by step introduces friction …
        • … better understand
          • what you want to build and
          • how the system “feels”.
      • … where your experience and taste come in,
        • something the current SOTA models simply cannot yet replace.
    • … end result will be systems and codebases that continue to be maintainable,
      • at least as maintainable as our old systems before agents.
    • … your product now sparks joy instead of slop.
    • … build fewer features, but the right ones.
    • Learning to say no is a feature in itself.
    • … still have an idea what the fuck is going on,
      • and that you have agency.
  • All of this requires discipline and agency.
