What a great inventor😉

Incredible how one person can devise so many different inventions… ðŸ’
It’s almost like there are underlying truths & arts that exist across disciplines.
The personal story is not so uplifting. A bit the same with von Mises.
Edison most certainly did not invent the things he is given credit for. He ran a research lab where he hired other bright scientists. When those people came up with ideas; he’d commercialize them and take credit for them + patent.
If anything he was a brilliant technical entrepreneur rather than an inventor.
