Wow these are extremely interesting results, specially this part:

> This gap between perception and reality is striking: developers expected AI to speed them up by 24%, and even after experiencing the slowdown, they still believed AI had sped them up by 20%.

I wonder what could explain such large difference between estimation/experience vs reality, any ideas?

Maybe our brains are measuring mental effort and distorting our experience of time?

I think just about every developer hack turns out this way: static vs dynamic types; keyboard shortcuts vs mice; etc. But I think it’s also possible to over-interpret these findings: using the tools that make your work enjoyable has important second-order effects even if they aren’t the productivity silver bullet everyone claims they are.
