No one is rejecting the role of leader, it's just extremely exaggerated nowadays, like everyone thinks Facebook==Zuckerberg. And the leaders don't worth x1000 (or even x1000000 for some) unless they are doing a job of 1000 people. In most cases they are not even capable of doing 99% of the work people in their companies can do. Egomaniac Musk has already published his thoughts on programming problems, only confirming how dumb he is in this field.
