> That PR, would have taken me at least a couple of days and up to 2 weeks to fully manually write out and test

What is your accuracy on software development estimates? I always see these productivity claims matched again “It would’ve taken me” timelines.

But, it’s never examined if we’re good at estimating. I know I am not good at estimates.

It’s also never examined if the quality of the PR is the same as it would’ve been. Are you skipping steps and system understanding which let you go faster, but with a higher % chance of bugs? You can do that without AI and get the same speed up.
