Edison was one of the greatest humans who ever lived and contributed more to all of us than any other person in the last millenia.

It's popular on the far left to try armchair criticize the greatest humans, but it doesn't alter the facts.

Thomas Edison's biggest inventions include the incandescent light bulb, the phonograph, and the motion picture camera. He also created the first commercial electric light and power system and is credited with improvements to the telephone, most notably the carbon microphone.
