Let me reply to you with a video:
Yes, anyone interested can try out ComfyUI, it will also run on OK GPUs but take a bit more time. The problem is it's only 5s of video, and getting something good takes a lot of tinkering with ComfyUI, not worth it IMO.
If it's one thing OnlyFans has taught us is that people like to connect with the actors, even willing to pay a subscription despite there being a huge amount of free porn available.
So at first glance you may think "who is going to want a fake g/f".
The problem with AI is that it's pretty damn good, and can be a more intelligent companion than many "real" people. It also glazes the hell out of you.
You think about how many abusive, narcissistic and self obsessed people are out there, and many people will be tempted to buy the idea that an AI companion who truly "loves" you is a good option, rather than take the risk of engaging with "real" strangers.
I mean dogs are popular companions for a reason, despite having the intelligence of a clingy 5 year old.
