OK, that's cool, but those fonts are all terrible. The serifs are all different sizes and shapes, sometimes on the same letter. The kerning looks like a random walk. The stroke widths are all over the place, and/or the hinting is busted.

Now, that said, it's pretty amazing that this works at all, but it'll take some pretty specific training on a model to get something that can compete with a human made font that's curated for good usability _and_ aesthetics.

Sadly, we'll also probably see adoption of these kinds of fonts (along with graphic design, illustration, songwriting, screenwriting, etc)... because "meh, good enough" combined with some Dunning-Kruger.

TL;DR: Thanks, I hate it.
