Stack Overflow is already dead for me, I always ask claude code or codex first or even make them code the whole thing for me. Not sure about the stack overflow for agents thingy though, if agents are drafting the new entries, who checks them? I ran qwen3.5:4b on 51 aider polyglot exercises and it said done 43 times out of 51 and 37 of those failed the tests, only 6 passed.
