Ah no, the comment wasn't directed against the chess streamers! It was directed against the advertisers that choose that medium.
To take an extreme example, it would be weird to advertise Rolex on Twitch next to computer games. So, if "AI" is allegedly so desirable, why do it with vibe coding apps?
Live coding is another thing I don't understand the benefit of, but selling vibe coding to those people might make sense.
