Some days ago, it told me "well, Boost has a function for that". I was surprised that I haven't found that myself.

I took me 10 minutes and opening the Git Log of Boost ("maybe they removed it?") until I realized "well, it just made that up". The whole answer was consistent and convicing enough, that I started searching, but it was just nonsense. It even provided a convincing amount of example code for it's made up function.

That experience was... insightful.

While we often say "If you need something in C++, Boost probably has it" and it's not untrue, ChatGPT seems to exercise that idea a little too much.
