> People praising it in the comments seem none the wiser (or perhaps they're also bots).

I am pretty certain most comments made on youtube these days come from bots. Google does not understand that this is a problem - no real human wants to "interact" with bots or AI slop. They kind of cannibalize youtube here (not that the youtube comments system was great, but you can find real humans making comments in the past, now you can not distinguish between bot spam and real humans usually, though most short comments are made by bots).
