I don't get the Tim Cook hate. The man picked by the venerated Steve Jobs has only increased the company's profit every single year since becoming CEO. Increased the company's sphere of influence in many areas of society. Increased the company's social and philanthropic endeavors. Increased the company's green initiatives and attention to humane labor practices and influenced other companies to follow suit. Holy crap that's a lot of sentence fragments. 🙂 He's done other things as well, but I think my point is clear. When judging a business, and not "my favorite company", it's hard to argue with the success of Cook's tenure at the helm.
He doesn't engender the cult of personality of Jobs, but so what? Jobs achieved success one way and Cook another. As a CEO, based on any quantitative data, I really can't think of any who've done a better job. Qualitatively, he hasn't done bad either. Neither Apple, Tim Cook, nor Steve Jobs is/was perfect; revisionist history notwithstanding. Comparatively speaking, CEO to CEO, I would put Cook's record against pretty much anyone else's.
To tie this back to the OP (apologies for the off topic rant), he is again demonstrating sound logic. Get the best battery people you can get to work on your EV. If rumor of the car is true, Cook is acquiring top level talent to try to make the project a more successful endeavor. He could have gone with the super secret double pinky swear in-house only route and more than likely failed. There's no guarantee the rumored project will be a success, but I doubt it will be because a lack of prep and planning.
TLDR; How many better CEO's are actually out there? What do people think a CEO's purpose is?
Sorry for length.
