The problem I have with tools like this (same as github copilot) is that I need to go ahead and double check if the AI did the right thing. At that point I might as well right the comment.
Completely disagree. Once you get really fluent in a language it is so much faster to write something from scratch. Especially if you have certain patterns you follow.
Code review is different because that has a different goal.
If you're writing enough boilerplate that you find it useful to have a little helper write boilerplate for you then you are writing way, way, way too much boilerplate.
If you have literally any boilerplate in comments then you probably have too much.
