I would completely agree with this if it said "All Cook and no Woz". I say this because I think it is unfair to label Jobs along the line of all the other MBA spreadsheet CEO's. Jobs actually had a talent for products. Woz and other brilliant engineers may have build these things, but Jobs had a talent for picking the right products, the right packages and the right timing that I don't think anyone else in Tech has ever really been capable of copying. I think that tech will always be full of Woz type people, but without Jobs it's going to be hard to get those products out there. I see a lot of it in Solar energy and Farming tech where a lot of brilliant things are being build, but a lot of it remains relatively small scale because nobody knows how to sell it.

I think you could also make the case for saying that the industry is full of Zuckerbergs (maybe Sam Altmans in a few years), but I'm not sure the advertisement industry is really all that related to tech. I know it may not be the most popular thing to say, but is there really that much of a difference between selling Tobacco, Coca Cola, Search Engines or Social Media? All are popular products which haven't really changed the world for the better.
