It's hard to self evaluate productivity. In a much simpler domain (decoding a cipher with a tool vs. by hand), I thought I was going much faster, but the stopwatch showed it was about the same: https://bobbiechen.com/blog/2020/5/28/the-making-of-semaphor...
Not feeling tired afterwards is a real improvement though, and I think that feeling is reliably self-reported.
AI is very effective at the boilerplate-heavy tasks that I hate and very ineffective at the architecture and debugging tasks that I love. We work well together.
