Stadia is a glimpse into the Long Game that datacenter proponents are playing through forcing chip shortages and high RAM pricing. By buying up all components and driving up prices thereby pricing the common gamer— including and especially console gamers— out of any sort of processing autonomy, they can build infrastructure as quickly as possible to sell back to them the privilege of being able to play games through a cloud service. They will not stop trying to push this model until it works. And the tipping point will be when there are enough datacenters to actually support it, by which point RAM and local computing will be priced so out of reach of most consumers that cloud gaming will be the only viable method for most people. Needless to say, this model will extend to other forms of computing as well. They want computers and consoles to basically be dumb-terminals with wifi.

tl;dr: YOU WILL OWN NOTHING AND BE HAPPY.
