One interesting feature in this paper is that the programmers who used LLMs thought they were faster, they estimated it was saving about 20% of the time it would have taken without LLMs. I think that's a clear sign that you shouldn't trust your gut about how much time LLMs save you, you should definitely try to measure it.

The study did find a correlation between prior experience and performance. One of the developers who showed a positive speedup with AI was the one with the most previous experience using Cursor (over 50 hours).
