The truth is tautologically unhelpful: choose good technologies.
Most people have trouble separating snake oil and fads from good things, so old/boring is a safe heuristic.
Nix is not boring, but it is honest. It's hard because it doesn't take half measures. It's not an easy learning curve gaslighting to you to a dead end.
But taste in choosing good technologies is hard to teach, especially when people's minds are warped by a shitty baseline.
