I'm pretty sure the hope is that this will lead to the development of a parallel track of game developers who make games that would otherwise be too difficult or expensive to make on old platforms. It makes sense on paper: latency isn't an issue because Google's network is excellent. The browser is a widespread and powerful distribution network which gives you access to both desktop and mobile. The cost of development should be lower because you don't need to buy expensive development kits and licenses/certifications. My personal view is that this isn't a technical problem but rather a bizdev problem, and Google's approach to solving things tends to be "throw out some tech and hope people use it," which is straight up not going to work with investment-heavy industries like games.
