One weird thing I've become increasingly skeptical of is promoting/advocating for classes of things rather than specific examples. For example, "blockchains", "sharing economy", and even increasingly on the fence about "public goods".

its usually a sign of romantic attachment to a philosophy which leads to cases of "solutions in search for problems"

Conversely problems in search of solutions get no love because people hate the problems so much they won’t even engage with them
