People who say it's not gonna work because of poor infrastructure and data caps are hilarious.
How many hours did you spend today watching Netflix, Youtube and/or Twitch? Maybe not many if you have data restrictions but there are people who can easily hit 10 hours of streaming daily. Your infrastructure may be poor but both Netflix and Twitch prove that there are millions and millions and millions of people who are not encumbered by it at all. More importantly -- paying people.
Once my ISP stops capping me at 1TB data, I'll take this dismissiveness seriously. Especially with not having cable, my kids and wife using Netflix (especially during colder seasons) quickly bump us near our cap each month.
Beyond that, even with a 100 mbps plan, my ISP has frequent enough outages where relying on the internet always being there would be crippling to my favorite hobby.
I don't know where you're located, Azeke, but in the US, ISPs have regional monopolies, which means they deliberately slow-walk speeds while kneecapping stuff like this with data caps. The same company who is trying to sell us the all streaming future also gave up on what could have solved that problem - Google Fiber. That's because they couldn't break past that same monopolization and pushing through local gov bureaucracies in order to force competition.
I'm fine with Stadia being a tertiary option on the market, and maybe Google has some black magic that'll make this work better than expected. But i'm not ready to take them at their word that they have the silver bullet that solves this problem.
