That depends.
If you have a high end gaming pc, probably not, but if you have a regular laptop or want to play on your tv, then I'd say yes
Edit
Should add that you need a solid internet connection

Do you care if you actually own your games? Or are OK with google owning the games, they just allow you to play them?

I trust steam to continue existing and providing access for a very long time. I do not expect that stadia will still exist in 10 years. If the service ends up failing, they aren’t going to have gaming hardware sitting around for you to use it.
