These posts are never, never made by someone who is responsible for shipping production code in a large, heavily used application. It's always someone at a director+ level who stopped production coding years ago, if they ever did, and is tired of their engineers trying to explain why something will take more than an hour.

It is also often low-proficiency developers with their minds blown over how quickly they can build something using frameworks / languages they never wanted to learn or understand.

Though even that group probably has some overlap with yours.
