In 2023, Carvana ran an ad campaign that showed you a video of "your car" thanking you and talking about your time together:

A little creepy, but very much in this vein.
We probably haven't even scratched the surface of what will be done with this tech. When video becomes "easy", "quick", "affordable", and "automatable" (something never before possible on any of those dimensions) - it enables countless new things to be done.
Its still just video though. Its not a new type of media. My guess is it will play out same as self publishing on amazon. Ultra specific generas that monitize the infinite long tail.
