I read another article some time ago, cannot think how to locate it, that suggested we might have had QM far earlier if someone had seriously pondered the question of what happens if one extends P to the range [-1,1]. I'm really looking forward to physics about 20 years from now, when a lot of the current work in mathematics and complexity theory and information theory has worked its way through the physics community. Valiant's evolvability and Deutsch's information constructor work and pretty much all of Aaronson's work will illuminate bizarre new paths.
