In another balance, I take guard when people say "I'm doing Node, and machine learning, and this, and that."

The reason is there seems to be a large number of programmers who "want to be good programmers" that do this. All that it really results in is a shallow understanding in many things with an accompanying attitude that they're smart, well cultured, or have seen a lot of things.

Dabbling in many different things is killing your learning curve because of all the context switching and you don't ever get awesome at any one thing. Putting those technologies or frameworks on your resume and blog like Foursquare badges doesn't mean anything. What have you done? Then and only then do I care about what you know.
