And Web Components won't stop frameworks from finding highly specific ways to be "useful" in a way where you need to do everything in them.
The solution is to know how to architect your app and stop believing marketing BS. Otherwise you'll keep fleeting to the Next Big Thing (tm) and never realize why it always ends the same way.
