If Edison hadn’t deemed one of Tesla’s most crucial radio wave-based innovations to be “impractical” back during World War I– when he first proposed plans for such–countless lives could have been saved for having the advantage of being able to detect enemy submarines. Of course it would be actualized until decades later. But just to think of what damage Edison’s ego-driven meddling has cost time and again is infuriating.
When we think about the invention of electric and its distribution, people think Edison as an independent hero in the invention of the electric light while sidelining other prolific scientists like Nikolai Tesla and Michael Faraday who held major roles in the development and distribution of the new technology
He conducted commercial practices in late 19th century to 20th century. Edison's enduring legacy isn't a specific patent or technology, but his invention factories, which divided the innovation process into small tasks that were carried out by legions of workers.
