Example 1: anyone who refuse new architecture or tech cause it is new (and that exists a lot outside startup world).
Example 2: anyone who jump into new tech even when it is irrational and not ready or simply not suitable for task at hand.
Example 3: all engineers who talk with utter conviction about history or art or political/social problem - after they spent like an evening on wikipedia and cherry picked whatever fit their pre-existing simple worldview.

All exists and are frequent.
