Before starting tasks, developers forecast that allowing AI will reduce completion time by 24%. After completing the study, developers estimate that allowing AI reduced completion time by 20%. Surprisingly, we find that allowing AI actually increases completion time by 19%

N = 16

What do you mean? I've seen people say that all the time on HN. No I'm not going to go and search for comments.

I meant actual data. You're refuting a claim backed by several cited studies in the OP.

Oh you mean when I said this?

I expect it helps people of all experience levels fairly equally, but only with tasks that are relatively simple.

No I don't have actual data, just direct personal experience of asking AI to do simple and complex tasks - it does much better on simple tasks, especially in very widely discussed domains (HTML, CSS, JavaScript, Python etc.) Ask it any SystemVerilog stuff and it gets it wrong almost every time annoyingly!
