I disagree for several reasons.
First off, streaming music and streaming video games are like apples and oranges. Yo don't need much to successfully stream music: an internet connection, a player, and a speaker of some sort. You don't need much bandwidth to have acceptable sound - even with crappy data connections. You can also take it anywhere and it's fairly unobtrusive.
Gaming, on the other hand, requires much more data, and at least a controller to have a decent experience. It takes at least 10 Mb to get a decent experience on Stadia. Problem is you're not going to get this often, if at all, I a public Wifi like Starbucks. Even at hotels, the "premium" internet offering often doesn't break 10 Mb. So the only reliable connections will be a cell connection or a private wifi connection. Not very portable.
Similarly, the experience overall isn't going to be that great. Who wants to game constantly on a 6" phone screen, as is often shown as the use case? Even when playing on a PS Vita, the experience was just OK. Not something I'd want to do for hours on. A PC/laptop makes more sense, which brings us to the next point.
Even if this is meant to be primarily a home service, there are a lot of problems with the idea. First off, MS is late to the party. There are already other services or there offering streaming, like Nvidia, Google, and Sony PSNow. They all have problems. Nvidia tried using games people already owned and just did the platformv thing and devs got pissed because they want to double dip. Stadia is struggling. PSNow has a lot of content, but it's missing a lot, and games come and go. It's more of a supplement for additional content, not an outright solution.
Secondly, content is getting stovepiped just like it is in video. Before, Netflix was mostly a one stop shop, and you might need Hulu for current programming. Everyone got Amazon with Prime. That covered it for most people. However, content providers got greedy. If you want Disney content, you have to go directly to them. Same with CBS, HBO, and more.
We're seeing that with gaming services. Ubisoft and EA have theirs, as do others. That's a lot of subscriptions to manage. How many people will be willing to pay monthly? What about buying games vs streaming them? If you buy them, they're yours. I'd you rent them, they're gone once you unsubscribe.
Streaming games may have a place, but it's too murky right now. Too many issues, and it's hard too see a consistent profit coming from these. Consoles will be here for a long time to come.
