In my experience with Codeium, it sometimes works ok for three or four lines of code at once. I've actually had a few surprises where it nailed what I was going for where I didn't expect it. But most of the time, it's just duplicating code from elsewhere in the same file, which usually doesn't make sense.

It's also pretty good for stuff where I'd usually build some exotic regex to search/replace (or do it manually, because it'd take longer to come up with the expression), like transforming an enum into a switch construct for its members, or mapping said enum to a string of the member's name.

This is very far from taking over my job, though. I'd love to be more of a conductor than the guy playing all instruments in the orchestra at once.
