to believe in stadia, you need to engage in magical thinking that allows you to believe that google has somehow managed to solve network latency and america's laughable internet infrastructure and just forgot to tell everyone.
I mean... Google has metrics, presumably. They can measure these things. They know what proportion of their traffic has adequate bandwidth and latency for their services.
Well, knowing Google, there might have been no requirements in the design doc, measurements are politically risky to bring up at a late stage of the project and perfecting code quality, rewriting, renaming and rebasing is a much safer occupation.
The US is not the world. The average person in parts of Europe and Asia has a much better internet connection.
In Germany I have 8 Mbit/s
Bandwidth has nothing to do with latency. A low-Earth orbit satellite connection could have 20 Mb/s bandwidth, but the latency on the round-trip for the packets could be 800ms, technically still under a second...but completely unplayable.
That's not the problem. You can have a "watchable" [0] video stream with 1mbit/s.
It is a problem with Stadia, because Google says you should have at least 10mbit/s
