"In 1990, with John Sculley's blessing, I left Apple with Marc Porat and Andy Hertzfeld to co-found General Magic and help to invent the personal communicator."
Sculley really wasn't the right person to lead Apple. He should have been begging them to do it in-house.
I don’t disagree with that assessment of Sculley but I’m not sure if that would have helped anyone. What the movie makes clear is that General Magic very badly needed adult supervision (all these “geniuses”! doing absolutely nothing of value! together!), and I’m not sure Apple of that era would have been capable of providing it in a productive way.
