I do think with advanced porn technology we could see some serious societal issues. Especially if they are controlled for profit by a single megacorp like all the dating websites.

But ultimately AI girlfriends are just porn, even if you'd have like an advanced version in virtual reality with cyberdildonics going down on you every night. I suspect most dudes will have no problem separating the fantasy because... aehm men won't get addicted to one AI girlfriend because they'll want a whole harem of them lol.

So if you had a local AI software running on a solar powered PC and graphics card, it would even be a completely ethical form of pornography, since it's both sustainable and you do not contribute to the demand for young women to do for money what most wouldn't do just for fun.

AI porn fundamentally changes the dynamics of the industry, basically a few open source software / open weight models made not for profit could completely "democratize" the access to porn. I honestly think being able to cut out the transactional aspect of porn is a major moral stepping stone of human evolution. Similar to a technology that could fully replace meat and make animal slaughter superfluous.
