This just feels like the wrong way around, I go to stackoverflow for stuff chatgpt can't answer. If anything, the right tool would be something which turns chatgpt threads into a stackoverflow question. (I don't actually think that is a good idea, just that it would make more sense)
Stack overflow gives you more than the answer, it gives you multiple answers for variations on what the OP wanted and therefore more options to try out. I guess this is useful when there are zero options provided or only crappy ones.
