I work at Google and I was immediately skeptical of Stadia (I don't work on that product, obviously). Partly from being a gamer myself, thinking about latency, but also because:
* Google has a reputation for abandoning services, and games bought on Stadia would be locked there. What happens if/when Stadia goes under? Who knows, but there's a decent chance of, "tough shit, all your games are gone."
* It's hard to get momentum when you're targeting hardcore gamers, who mostly already have consoles/PC's, thus removing one of your biggest advantages.
