No, sister lady. It'll be good in South Korea and Japan. US? Europe? Not so much, probably. Some of us will get decent quality, like the Project Stream testers. Maybe me if I'm using Ethernet at home. But a lot of people are not going to be able to use Stadia.
Tin foil hat? We had facebook vs google+, now stadia vs that one service that no one can remember, to play from your house using another computer to run your game, but with my coutry internet? pfffff
Can it support 4k resolution at 60fps uninterrupted without constant DRM? Does it have mod support? Can it play intense action games like DMC5? No? How unofrtunate.
Given that Google is one of the biggest fiber internet providers in the USA, they MIGHT have the infrastructure to make this work. Maybe give Google Fiber customers a discount on Stadia?
Also, remember that Google is one of the largest providers of fiber internet in the USA. They are already building the perfect infrastructure for this service.
