I sometimes wonder if they're vulnerable to a coordinated effort of deliberately upvoting shit assistant turns and praising in the next user turn - how much does that actually contribute to future training, if at all? I had a very basic React question about useState while porting some vanilla code last week which all models of all stripes I've tried it on have been confidently and completely incorrect about, up to stating the code absolutely will not work, even when I take a turn to assert that I ran it and it does, so there's plenty of shit in there already.
