Also, generating images and programs are basically orthogonal. AI could generate impeccable photorealistic images of clocks years ago, and they're much more complex than font glyphs (specifically talking about transferring a style to other glyphs; you still need to do the initial design to get something appealing, obviously*).
*Edit: Maybe AI can even handle the initial design now, not sure. What I’m saying is AI-assisted style transfer in CJK fonts is definitely old news and commercially available.
