Tesla was too wrapped up in himself. If he had been a little more willing to communicate and share with other investigators (you know, that "peer review" thing), more of his discoveries might have been preserved, discoveries that are now lost.
Also, he might have avoided going down the dead ends that he wasted his later years on. So conscious of his own superiority, he couldn't take input from "lesser" men.
Ha peer review? He had enough of his ideas stolen from him ie marconi. Supreme Court ruled in the 60s that tesla had indeed invented not only radio but remote control vehicles. Marconi still gets the undue credit.
Tesla had personality disorders no doubt, but his genius is unrivaled, maybe Archimedes, Di Vinci.
Read some books about him, you will withdraw your statement.
