Since 10+ years ago various YT channels have been creating interesting content, sometimes on less than a normal salary, filmed with a phone and with one person acting for three characters at once. And imho they (fortunately) won't disappear if what you linked is representative for what AI enables.

None of the videos I've clicked on required AI for the content to be good, and some of the randomness has no real reason to be there.

Most of those "skits" can be done on a cheap camera with a single person being the actor. In fact, many such videos existed already in the past.

Also, they're painfully unoriginal. They're just grabbing bits that The Onion or shows like Rick & Morty have been doing and putting a revolting AI twist to it. It screams to me of 0 effort slop made for the sole purpose of generating money from morons with no creativity clicking on it and being bemused for 10 seconds
