This video is specifically content that's not popular, but appears to be rendered (live) with a human artist's own selection (perhaps randomly chosen, perhaps more algorithmic) of cutting, filtering, defocusing, etc. Maybe this difference is more subtle than I imagine. But I think it's clear that although this is probably content that The Robot Did Indeed See, it is not a representation of Twitter's or YouTube's algorithms' interpretations of that content.
The algorithms that generate the visuals and sound are generally traditional ('cept for the eyeballs: OpenCV) but use machine learning to make decisions. So the "AI" are editorial rather than generative. See the website for more details..
There are various machine learning algorithms in the mix, but primarily in the back end.. they generate the section labels, talking heads and eyeballs, differentiating sound/music for the sound mix, etc. They also filter "spam" videos. Many of the "AI" algorithms are behind the scenes or not the focus of attention (since it's what the robot saw, not how.) The lower third supers on the talking heads are more what you were probably expecting. But it's something very specific (not my algorithm) and explained on the site.
