Job's read and perception of where things were going is very impressive, hard to think of anyone today who could be this eloquent and persuasive...
That's basically the only reason I like to listen to the big VCs, because they're actually terribly open about their thoughts unlike virtually all CEOs. Because they also use their vision of the future as a marketing move. Someone mentioned Naval for example, that's no coincidence I think, angel/venture investors cluster quite high on my list of people talking openly about their perception of where things are going (regardless of whether it's a correct perception or not).
Nothing to do with how they conducted their lives.
Not a time waste. Look at Elon. He spends a lot of his time in engaging at Twitter
The fallacy is thinking Elon uses Twitter like any other person uses Twitter. Sitting on his device, manually scrolling through it and replying sequentially. He's probably outsourced much of this to his media teams or other people he trusts to provide relevant material to engage with.
