That said, we do still talk about Edison, Carnegie, and Rockefeller, over a century later. A millennium? Probably not, but the point is valid, even if off by roughly half an order of magnitude.
So you'd expect that someone who rises in the general consciousness now to actually be far more impactful than the 'ancient greats'.
This must be the first entrepreneur/capitalist/CEO that has been mourned on such a global scale, and that in itself is remarkable; there's no one who comes close. Maybe Warren Buffett, but outside of the US he's not that well-known. The only person I can think of from modern times might be Walt Disney, someone who was similarly creative, demanding, and left a cultural and commercial legacy behind.
