not that I disagree with you in principle but I see this the same was a "cloud" - 10's of thousands of companies could save gazillion dollars by hosting their infrastructure and yet they continue to pay insane amounts of moneys to AWSs and Azures and whatnots. While some company's future may as well be running local models I would venture a guess that vast majority will just eat the costs and pass on as much of it as they can to their customers...
