As a web developer for over 15 years, I can safely say that bad decisions will continue to be made. Such as, CSS-in-JS. Expect the worst. And it's not completely Google's fault although they should never have bothered to invent WebComponents, this sort of thing comes from the hubris of CTOs and technical leads who are the ones pushing these various technologies, and the acolytes who desire these positions following suit. Believe it or not, some people like to use certain tech to satisfy their own personal itches and not because the tech is actually demonstrably better.
