Why there is(was) a rivalry between Tesla and Edison?
gpt
Tesla looked up Edison as an idol in his young days and he had a lot of brilliant plans. Edison felt like there would be competition with Tesla's plans so he hired Tesla and told him "I'll bet you $50,000 that you can't finish this project (maximizing efficiency of electric current)!" When Tesla finished, he went to go get the money from Edison but Edison told him "I was just joking with you! It's an American joke". Tesla immediately quit, but he went to work for Edison again because he had no where else to go for work. Edison, in return, hired him back to dig ditches. Tesla was fed up with Edison and teamed up with Edison's rival (George Westinghouse) to promote the use of A/C current of electricity. Since this would create competition, Edison told everybody that A/C current is bad and he tried to prove it by using A/C current on an electric chair to scare everybody. However, Tesla defeated Edison when he used his idea to bring electricity to the city of Buffalo in New York through Niagara Falls.

tl;dr Edison screwed Tesla over. Tesla got mad and launched a competitive way to beat Edison. Edison launched a PR campaign to slam Tesla. Tesla won by providing electricity to Buffalo, New York.
