I'm almost certain that React will evolve with the native APIs. Or maybe that's wishful thinking, but Facebook has been pretty on the ball with these things. React's greatest advantage at present, in my mind, is React Native.
Not yet, but I find the theory enticing. The author's major complaint - with which I sympathize - concerns standard implementations vs. frameworks like React. With React native, the point is rendered moot as there is ostensibly no comparable solution. Let's see if it lives up to the hype.
