First off, I am sex positive, pro porn, pro sex work, and don't believe sex work should be shameful, and that there is nothing wrong about buying intimacy from a willing seller.
That said. The current state of the industry and the conditions for many professionals raises serious ethical issues. Coercion being the biggest issue.
I am torn about AI porn. On one hand it can produce porn without suffering, on the other hand it might be trained on other peoples work and take peoples jobs.
I think another major point to consider going forward is if it is problematic if people can generate all sorts of illegal stuff. If it is AI generated it is a victimless crime, so should it be illegal? I personally feel uncomfortable with the thought of several things being legal, but I can't logically argue for it being illegal without a victim.
