Ok, we'll expand to porn and gambling
- images - payment systems - stored video - banner advertising - performance based advertising - affiliation - live video - video chat - fora
Etc... AI is a very logical frontier for the porn industry.
Just because things can be used for porn, it doesn't mean that it was porn that has driven their progress.
I don't remember any of these being "driven" by porn. The first applications weren't porn-based. Maybe live video--a split second after seeing the tech for the first time, probably 99% of guys were thinking of _applying_ it to porn. But, even for the usual money-grubbing startups, there was plenty of money coming from non-porn sources. Probably no different than the invention of camera, tv, videocamera, etc. and you wouldn't say porn drove that.
