Stop peddling meaningless hype. Current 3D rendering technology is lightyears ahead[1] of these AI toys and you can trivially parametrize it. Many games already do. So if you want to generate people, you already can do that while having full control, instead of some glitchy sliders. Something genuinely useful might, perhaps, be achieved by applying GANs to parameters of those 3D models to allow easier customization, but I haven't seen any work in that direction.

The video is very nice and it's really good, however it's often not really photorealistic when it's supposed to be and I also don't believe it'll be possible to do raytracing at such performance it'll be usable for most people (mobile phones), for VR. This approach is a new way that sidesteps the issues of raytracing.

With all the work on making these ML models controllable it seems like they now have a decent concept of things like "tall person" or "wears glasses". I assume it would be entirely possible to replace the last few layers and generate 3d models instead of images. Nobody is doing that right now because nobody has training data for that, and generating such training data is hard (or expensive). But it seems like it should be in reach of someone with a profitable use case.

  I expect that data to grow quickly over the next decade, assuming things like the 3D selfie camera on iPhones end up on the main camera too. (I expect they will end up on all the cameras, just for the value they’d add to AR).
