I never said it wont be the Netflix of gaming but I think its rather funny that this thread is calling it that now, when majority of the world don't even have access to it or know of PSNow. I am guessing because MS came out and said that xCloud is aiming to be the Netflix of gaming, all of a sudden PSNow is considered a bigger streaming service so its the real Netflix of gaming because its one of the first even when Sony is actually using a much smaller infrastructure to the MS, Amazon and Apple. That's why the title is a little misleading to me.
Many sites have described PS Now as the Netflix of gaming e.g. Trusted Reviews back in June 2018 (link). It's a practical term in order to explain the concept of the service (you stream your games, just like you stream your movies). That's why Microsoft uses the same term which you don't seem to have a problem with.
I agree that it's too early to say what service will become the Netflix of gaming regarding to market share and popularity. That's why I struggle to understand why you're ready to give xCloud a bigger chance of becoming that.
