Oh I agree that GPUs should be more commodity. We might see alternative ASICs rather than GPUs come out though. I'm personally more interested in seeing that succeed than just confining the solution space to gpus and discrete gpu competition. I'm just not keen on trying to predict what will win (I really don't know) I just have criteria I would be looking for before trying to implement support for it in either my deep learning framework or trying to support anything for customers.
