I'm not sure. I have a buddy that's one of the better engineers I know personally, and he struggled to maintain an "AI Lent" for even a month. He found he just wasn't productive enough without it.
He did a writeup: https://buduroiu.com/blog/ai-lent-end/
> I delivered more work that I was less confident about, making me more miserable in the process
Don't leave the kicker out of the story
