I think it is a fair possibility. A few years ago, everyone was raving about jQuery, because it was solving "real" browser problems. But now the DOM APIs are better, and you might not really need jQuery .
I don't know the specifics, but just throwing out ideas in the air, probably browsers in the future will ship with a virtual DOM implementation. Then, probably, we will have some thing like youmightnotneedreact.com :D
