> centaurs (human+AI) in chess/go were better than either humans or AI just for a short time.

I was having a conversation about this with a friend last weekend, and we'd assumed that centaurs were still better than either top humans or top computers. I'm unable to easily find this info on google, could you share where you saw that centaurs are no longer better than top computers?

I saw it here, perhaps, in articles about competitions where both humans and computers were allowed (computers-only teams won). I too can’t find anything relevant on google.

True, but while the 'best' chess is played by computers, few people care to watch Stockfish playing with itself. Meanwhile the human-powered chess world is enjoying a surge in popularity.
