My point isn't to get into a skills based dick measuring contest, but rather to point out that even at huge technology companies*, is being technically adept really a requirement for the job?
Another one for discussion: is Apple a "technology" company? I put forth that a company is defined by the most difficult problem they need to solve / continually solve in order to stay in business. That tells me Apple is more of a manufacturing/ marketing company than technology.
Lisa Su demonstrated an impressive skill not every CEO could pull off and I wanted to highlight that. That's all.
Whether being technically adept is a requirement or not, I'd say no in general for tech companies (and I'd count Apple as one) but for a certain subset of the tech companies (AMD, Tesla) it certainly seems to help.
I mean it's like asking Tim Cook about a different strength cellular antenna in the iPhone. Probably he could give a reasonable answer about what the iPhone antenna is actually like and why it's like that, and how many tests they ran to confirm it's the best design or whatever. But could he talk about an alternative antenna that could have been, on the spot?
