People can hate all they want, but facts are facts. There is no such thing as the solo inventor anymore (arguably, there never was) – only incremental evolution that eventually is done right and combined into a product that changes or creates an industry. Automobiles existed in various forms before Ford came along. Had Edison not usurped Tesla, the history books would be crediting the latter with the birth of the modern electrical age. The Wright brothers emerged from obscurity just ahead of their competition…. if they had waited a bit longer, history would have never heard of them.
Jobs had a better track record than all of these guys combined, save for possibly Benjamin Franklin. He had vision, and he knew how to assemble the right team to execute it. It isn’t just marketing. Something must eventually be behind the marketing, and Jobs always backed it up.
