I'm not really sure I understand the author's point. I also disagree with his definition of general-purpose. My car is a general purpose transportation device. Does that mean it is an all-purpose transportation device? Of course not. It solves almost all of the problems I have related to transportation, though. But there are times I explicitly want to pick a different mode of transportation: 1. I need to cross an ocean: Choose a plane/boat 2. I need to go where there are no roads: Choose legs 3. I need to haul significant quantities: Train/Truck 4. I need to prioritize speed: plane 5. I need to prioritize attention: choose a subway/bus Does this mean the car is the best form of transportation? Also no. But it's still very much a generalized means of transportation within our current context. It handles a user's daily and most consistent needs. This is also true of our current processors. The author's definition of "General-purpose" appears to be impossible, which makes his title both true and useless.
