A bad CEO can make everyone unhappy and grind a business to a halt. Surely a good one can do the opposite, even if that just means facilitating an environment in which key workers can thrive and do their best work.
Edit: None of that is to say Sam Altman is a good or bad CEO. I have no idea. I also disagree with you about iOS, it’s not perfect but it does the job fine. I don’t feel like I’m eating glass when I use it.
