Man I almost had to turn that video off because of the ridiculous conspiracy theories layered within, and the misinformation about Tesla. I won’t go into it that deeply but if anyone here is a fan of Tesla and the electrical revolution then check out Wizard: the life and times of Nikola Tesla, it was an excellent biography. Long but really good.
The main thing I wanted to mention about Tesla that is, in my opinion are 2 big misconceptions, the rivalry between him and Edison; and how he was supposedly screwed by investors (mostly JP Morgan) on a regular basis. The Edison-Tesla feud was greatly exaggerated by the media of the day (not much changed there), and while Edison did steal the occasional patent design here and there (and honestly everyone except Tesla did back then), he didn’t go out of his way to bury Tesla. Tesla screwed himself because he was terrible at business, and also would spend investor money on non related projects. He did it to Morgan more than once. So when Tesla asked Morgan to be an investor in Wardenclyffe he asked for $100k (for a 150 ft tower), Morgan agreed to $150k because he knew Tesla was going to waste some of the funds. Then Tesla desides to go for a 300 ft tower and asks for more money, Morgan refuses and the project flopped. Tesla did stuff like that time and again, and was also really bad about retaining a portion of his patents. He wanted to make things for the sake of the invention itself, as well as his ego. If he had a good business partner that could have stroked his ego and kept him on track with projects that would bring a profit we would be in a very different place technology wise today.
