It's actually scary how badly the industry wants cloud gaming to happen. They attempt again and again, even in the face of over a decade of failures that include Google.
It solves so many problems for them. No piracy, no second-hand sales, no public libraries, no cheating, and perfect player stats. They can take the game away whenever they want, and make you pay for it again in the future.
Technical issues didn't doom Stadia. Being part of Google doomed Stadia.
Stadia was only going to last as long as the Google promotion cycle.
It's true, not all of the services died due to technical issues.
GForceNow and XBox Cloud are doing ok, Stadia problems where managemnt related more than anything else, how they forced rewrites, how they don't know how to talk to game devs (ads KPIs instead of game tech), and their whole promotion cycle.
In theory there is no real impediment to largely indistinguishable cloud gaming platforms using edge datacenters. Of course, Microsoft's ecosystem has resulted in depence on battlestations over tablets and laptops for gamers.
Programmers depend on non-system libraries largely these days.
