Seriously, the old guard of tech need to quit hiring old-guard CEOs who have little clue on leadership and innovation.
Stop the agism. It isn't that they're old guard. That idea should bite the dust as surely as the idea that the problem was an "old boys club".
It is that top executive management comes from sales and marketing.
Managers, marketing types, they're loners know nothing about technical innovation, nothing about innovation on teams, nothing about the technology, nothing about the physics.
They're detached from the programmer and engineer class, which makes it super easy for them to lay such "technicians" off.
They can drive an entire mega-company into the ground without a moment's guilt over drawing a huge salary while failing to deliver the success shareholders are paying them for.
