idk maybe successfully founding & managing (currently) BIGGEST technological company for 3 decades,

that's main driver behind the biggest technological innovation of humankind requires you to be quite smart, don't you think?

wtf

>terms of engineering and development, that makes you think he's smart?

yes, because only engineering and development requires smartness! Do you really think it is true? wtf

>Idk I always find difficult to believe that people really think that CEOs are smart, when they commonly are not involved what so ever in any scientific leading or research, and just funnel money to a product that make them richer.

If you really believe that picking what to invest is easy, then go ahead to the stock market - you should outperform it easily then.

what the fuck is this take :D
