I don't think React vs Unity is the debate that we all cant wait for it to happen? After all, Web has DOM tree as its fundamental data structure to fiddle with, while Games are just a series of objects that can orient/interact with each other however they like. And obviously performance reason will affect abstractions as well, e.g. the Micro/Macro Kernel debate. To say Unity isn't good enough because React is good at abstracting Web development away doesn't seem to hold too much ground in terms of logic coherence
