I disagree that the reviewers lacked long term vision. Nearly all of seem to have been burned by the promise of videogame streaming before, and the current state of Stadia only inspires cautious optimism at best.
You're right that everybody wants to live in a world where videogames stream anywhere at 4k+ and 60+fps with minimal latency. But OnLive was 2010. Gaikai was 2012, followed by Playstation Now in 2014. This space isn't a greenfield for lack of trying.
Furthermore, with initiatives by Microsoft (Project xCloud) and EA (Project Atlas), there's no reason to accept Google as the standard bearer for game streaming. There's plenty of companies that could be coming up with the experience we've been waiting a better part of a decade for.
