The bet is that models get better faster than code gets worse. Looks like so far it's correct, as Fable can already write better code than me and most others on average.
replythe thesis of the post is that this is not true. fable can solve more problems but for complex systems it is not sufficiently diligent that you can turn the lights off.
replyThey turned the lights off in 2025. The post is simply not accurate to today, they even say so, stating that apparently no one has proof of better models in 2026 improving codebases over time. I've seen it happen but the author hasn't apparently, so it's a game of "you said I said", not anything concrete.
reply(op here btw) - the question isn't "can models make code better" - its "left fully unattended, will they turn your codebase to slop over time"
replyfrom the footnotes (sorry if this got a little buried)
> yes of course you can get gpt-5.5 xhigh to do BRILLIANT refactors. But you had to tell it to do that. And to tell it to do that you had to understand your codebase well enough to know it needed doing. We're here talking about why lights-off wont work
i suppose this would also be a good place to ask if you fall in the "high stakes production systems" camp
> If you love vibe coding, please, go on vibing. I still vibe code lots of things, I just also maintain lots of production software (and through HumanLayer, help 1000s of other engineers do the same), so the rest of this is aimed at folks solving hard problems in complex codebases.
