I think what that is demonstrating is that models are commodity objects. The model factory may have a value. I think it would need a specialized context. It would need a market large enough to support it and small enough to keep the context out of the mainstream.
My guess is this will always be a moving target. The consumer will choose models based on their value proposition.
Hmm. I see a lot of people trying to build products on top of models trained by other people, which seems very vulnerable.
