I bet Albert was right. The instantaneous effect of a measurement is definitely spooky.
Wavefunctions require complex numbers. Geometric Algebra (I've temporarily stalled at Chapter 5 btw) provides them for free as a wholly natural phenomenon, provided that noncommutation is acceptable.
Therefore...
Other clues to the intrinsic depth of Geometric Algebra hinge upon the natural emergence of Pauli and Dirac spinors - heretofore god-given guesses in physics.
