This is false. Here's an exhaustively researched 4.5 hour video on the topic if you're interested in what Edison was really like (an incredibly hard worker who was much kinder to his employees than was usual for the time, and who changed inventing from an art into a science), and the by-all-accounts positive nature of his very brief working relationship with Tesla.
Edit: I am absolutely gobsmacked that this comment is getting hammered so hard in a science community of all places.
I guess the misinformation-fueled hate boner for Edison is just too strong for the truth.
Got one not from a channel that wholesale publishes sponsored work?
Edison was a monster by every contemporary and modern account. I don't know who paid him to narrate nonsense, but let's not rehabilitate one of the worst humans on the planet.
I love it when you get millionaire (who would likely be billionaire) bootlickers in comments like this because you can almost always go back and check their replies. Low and behold, within the first few posts you immediatey get MRA shite.
