For a while it seemed that having deeply held, nuance-free opinions about technologies was a sign of being wise and experienced.
The slightly lighter version of this was having near-absolute convictions but leaving a tiny exception for extreme cases to try to demonstrate that you weren’t being unreasonable.
These would usually follow trends when something would spread like a meme. Recent examples include “Everyone should use SQLite for everything” and the ironically closely related “Just use PostgreSQL for everything”. The typical pseudo-nuance would be “unless you have FAANG scale” to imply that there is no nuance until your user base includes most of the developed world.
