It is useless to cowardly downvote an unpopular opinion without giving any reasons or because you don't like the style of a comment. Cosplay of political-correctness huts the truth and sometimes a form (wording) matters a lot.

Well-researched thing will always beat fast-coded-to-market crap. Erlang (despite all its syntactic ugliness), Go (especially stdlib and runtime, which is hard), Scala, Redis, nginx, Haskell (monad-madness aside), Clojure etc, etc.

Ability to produce a lot of crappy code quickly is not a substitute for a decent academic research with proper attention to details. This is the point. Postgres was a research vehicle in the past, now polished to a state-of-the-art product, just like SQLite.

How is MongoDB, by the way? Still a default choice or it has been recently obsoleted by a blockchain?
