I've been trying to generate AI futas for years. Stable Diffusion finally gave me the tools to make an infinite variety of proud, happy futas, and how could I keep that to myself? I'm building tools, designing systems, experimenting, and basically teaching myself (more) AI and computer vision programming. I see a mostly automated system that accepts user-supplied images (or NFTs) for custom AI porn that doesn't have to be futas, but that's where I'm starting, because reasons.
I do have a dayjob and a busy life though, but if enough people see the value of positive, non-exploitative representations of nonbinary bodies, then I can spend much more time on it.
And yes, I do plan a "futanize yourself" service.
