Porn has driven many tech advances. I predict that models trained on specific porn genres will appear as soon as training a good model is doable for under $5000. They’ll get here much quicker if we get video to that mark first.
Have you ever seen a non-porn DVD that had multiple camera angles (a feature defined in the standard DVD spec)?
This is an urban myth.
I'll even say that the high bandwidth push in the public was highly related to that. Even HTML5 video players, adult websites were faster to implement it than big streaming websites that still used flash or similar tech.
