If this works, humans can't possibly compete. Not on the scale that virtual people can. This is simply another step towards a kind of singularity.

I suspect the most competitive virtual supermodel would be that created by a person (say, some schlub) who desperately needed to be such a supermodel and could handle themselves in that situation: projecting their own desired identity through the mask, to animate it.

Or, created by an AI which itself is a needy schlub that craves validation and can handle itself as a supermodel. There's no reason this hunger should be exclusive to humans only. And an AI would have greater bandwidth for learning what the public wanted from 'it as a supermodel'.
