When it's best suggestion (for inline typing) is bring back a one-off experiment in a different git worktree from 3 months ago that I only needed that one time.. it does make me wonder.

Now, it's not always useless. It's GREAT at adding debugging output and knowing which variables I just added and thus want to add to the debugging output. And that does save me time.

And it does surprise me sometimes with how well it picks up on my thinking and makes a good suggestion.

But I can honestly only accept maybe 15-20% of the suggestions it makes - the rest are often totally different from what I'm working on / trying to do.

And it's C++. But we have a very custom library to do user-space context switching, and everything is built on that.
