I'd rather have AI porn that doesn't involve human trafficking, massive exploitation, actors/actresses with a high suicide rate, child abuse, and all of the rest of the evil/bad things that the porn industry currently has.
massive exploitation
Every "AI" algorithm that exists only does so because of billions of obscenely underpaid hours of labor in the third world.
AI isn't being developed in third-world countries. I don't know what you're getting at.
OpenAI Used Kenyan Workers on Less Than $2 Per Hour to Make ChatGPT Less Toxic
This is just one example of many. Tagging millions of images to train algorithms has to be done with real people, and companies like OpenAI use platforms like Amazon's "Mechanical Turk" to pay people in developing countries to do it. Without this massive amount of labor, generative algorithms wouldn't be possible - and that's before getting into apps that have just used writers in poor countries directly while pretending to be a computer program.
Can [cars] be ethical? Can [rocking chairs] be ethical? This question is nonsensical. "AI porn" is the output of a production process.
Are we being asked if it can be produced ethically? Or possessed ethically? Distributed ethically? Ethics are things that apply to conscious creatures, not inanimate objects.
