Pornhub has an AI R&D operation. So far, they've mostly been restoring really old porno films from 1900-1920. Presumably they have work underway on generating content directly. As they point out, they have plenty of training data.
It is always amazing how much technological impact the porn industry has. Media standards, streaming, filming, you name it. But then one of the first large internet use cases was porn.
it still is one of the largest internet use cases today, iirc ~30% of all web traffic is porn.
One of the first uses of film, too. In fact one of the earliest uses of writing -- mosr Egyptian writing fragments are either receipts or (text) porn.
