Google Stadia is the Google Plus of game streaming:

Lots of exuberant early adopters shaping the platform.
Eventually Google will change it to appeal to a broader audience.
The exuberant adopters will leave, adoption won't happen as quickly as Google would like.
Eventually someone in Google will stop funding it and it will die on the vine.
Tech pundits will both extol the virtues of the platform and eulogize it, or they will say it was foolishness from the get-go

Wash, rinse, repeat.
