If you post a question, Stack Exchange with all their clever AI produces a list under your title called "Questions that may already have your answer". This makes a lot of sense for Stack Overflow, where duplicate questions are to be avoided. It makes a lot less sense for Code Review, where the fiftieth "Tic Tac Toe in Python" is as welcome, and deserves bespoke review, as the first.
While there may be some advantage to some users who click through a few of them and learn a few tricks about their problem or asking a good question, I suspect that on balance it causes more confusion and leads instead to users either not posting at all, or posting not-an-answer answers to and resurrecting long dead threads.
