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?

Part of it is that I feel I don't have to put as much mental energy into the coding part. I use my mental energy on the design and ideas, then kinda breeze through the coding now with AI at a much lower mental energy state than I would have when I was typing every single character of every line.
