People do it with the autocomplete as well so I guess there's not that much of a difference wrt LLMs. It likely depends on the language but people who are inexperienced in C++ would be over-relying on autocomplete to the point that it looks hilarious, if you have a chance to sit next to them helping to debug something for example.

For sure, but these new tools spit out a lot more and a lot faster, and it’s usually correct “enough” that the compiler won’t yell. It’s been wild to see its suggestions be wrong far more often than they are right, so I wonder how useful they really are at all.

Normal auto complete plus a code tool like Claude Code or similar seem far more useful to me.
