  1. Our readingThe case for sweating every line of code was premised on humans doing the modifications, and it now survives only because tokens are scarce.

    Their wordsThat was premised on humans doing the modifications. I think it is an open question to which degree this still matters. Now, it does matter, and the reason I say that, at least for the moment, is that tokens are still scarce. At this moment in time, we are all token limited.

  3. Our readingAI acceleration threatens 'less software': without the constraint of scarce hours, even 37signals will likely build too much.

    Their wordsSo, this is why I'm quite skeptical about all this new AI acceleration we're having is even us, I think it's quite likely that we could use it wrong to build too much software, to get too far away from less software, learnable software. It still has to fit in the mind of a human.

  5. Our readingThe prediction that 90% of code will be AI-written by the end of 2025 deserves skepticism, though manual programming may yet become a horse: ridden for love, not transport.

    Their wordsThe Anthropic CEO seems to think that 90% of all code by the end of the year is gonna be written by AI. I am more than a little bit skeptical about that, but I'm open-minded about the prospect that programming potentially will turn into a horse when done manually.
