I have been reading about edison and there are a lot of parallels between him and elon. One thing which stood out was that often a new technology needed hype and promise (aka vapor ware) to keep the interest going and capital flowing in. Edison did that with the electric bulb and was a showman.
Ofcourse charlatans do it too and hence its tough to differentiate in the begining. But as edison proved himself, the next time he made claims, people were ready to back him.
often edison would claim his invention was working, while he was feverishly trying behind the scene to make it work
I agree with @rkbabang - there have very few, handful maybe of people who have pushed technology forward to this level and here elon is doing it in multiple fields and from a position of strength compared to someone like edison
I was hearing a podcast with jensen huang and Xai stood up a data centre of 100000 GPU in 19 days where as it takes 1-3 years to plan this kind of this and no one has gone beyond 30000 GPU till date
How much more evidence do we need that this guy makes stuff happen even if some of his moonshots fail or are delayed !
