It doesn't seem like any of his proposals would have even remotely the impact of Apple's work in 1984. Actually, even compared to the concept of a touch screen phone that works as they developed in the iPhone. Maybe I'm missing a joke here, but I'd say that he's not in a place to criticize if he thinks that "object-oriented drawings" or "wiki namespaces" are going to be more useful innovations than even the tiniest detail of what Apple, or, hell, Microsoft is doing.
