I don't think Jobs was talking about engineering there, he was talking about business decisions. Look at these quotes from the last set of exchanges: You have the chance to set the tone for a new platform. For the new phone and tablet platform. The platform of the future! I am disappointed to see it’s the same old revenge power bullshit. By the way, what have you done that’s so great? Do you create anything, or just criticize others work and belittle their motivations? (Emphasis added) Jobs mentions several times it's a business decision for the platform made to create a good customer experience. Incidentally, I wouldn't be bothered by a scientist who had that attitude, if he was given vague criticism by someone without a physics background.
