Can we please drop the "cool kids" cliche? It's a tired generalization.
Worse, 'cool kids' implies doing something because someone else is doing it rather than because it's the right thing to do in your organisation. It smacks of cargo cult behaviour - copying actions and hoping to get the same end result without understanding why.
I think it's actually the exact phrase we should be using. I work with helping beginner programmers learn to code and if they want to know "javascript" (they don't even know what that means) they are always asking for ember/angular/node and when I ask why they want to use these technologies or what project they are working on that would benefit from that style they blank. It's definitely cool kid syndrome.
