Good. I really hope Stadia fails. Gaming is one of the major drivers of continued demand for "real computers" at the edge. Take that away and we'll lose even more momentum there.
I hope Stadia or a similar service succeeds, because I'm one of those people.
Anecdotally, as someone who games regularly, I never even looked at the Stadia. It was of 0 interest to me. I suspect most people in my position feel the same.
