Find someone who calls himself a “full-stack developer” and smack him right across the face for being a liar or terrible. (Umm, don’t really do this: Violence is wrong.)
I’ve not run the numbers, but I estimate that less than 1 percent of the developer population can make an adequate-looking webpage and a fully optimized data storage layer, let alone business logic. Just because you made everything JavaScript doesn’t solve that fundamental problem. Most papers on quantum physics are in English; I speak English but I’m not automatically a quantum physicist. As one developer I know put it, that’s “boss-logic.”
