I don't get this view. They really did show compelling, game-changing features for the end-user, if you watched their talks and demos. They showed lots of potentially game-changing features for developers too, which impact the products, which impact the users.

Most of it is vaporware at this point though, and what we have in Stadia today is basically an early MVP.
