I just watched the editing of the google stadia video and think there are some caveats.
Just as android have APKs, I fully expect stadia to have STDs. However much of what's happened on android is useable on home grown Linux (or the source is somewhat bearable) and I'm PRAYING TO LUNDUKE that stadia apps/games/STDs works their way to the linux kernel 5.whatever.stable.
It might be a pipe dream as a lot of APKs are, but the future isnt...EOF
STDs may be the future of gaming, but lets hope not.
