I may be wrong on this, but I thought it was most scientific to view everything as 'theory' rather than 'fact' because science is still developing and there are always new theories to supplant the older ones as we grow in understanding.
Yes. There isn't any thing as scientific fact. The distinction is usually between theory and hypothesis, and the video belongs to the latter category.
I personally don't buy into the "quantum thought" hypothesis. It is based on the assumption that human brains can do computations using qubit-based operations, which is very tentative. For example, quantum computing devices, as currently postulated, would be able to factor huge numbers in log(O) time, while non-quantum computers factor numbers in O factorial time. Humans factor in O factorial time - even idiot savants gain their ability from fast math thinking (i.e. a tiny coefficient in front of O!), not a log(O) algo.
Quantum computing also doesn't explain "consciousness" any better than ordinary computing. In fact, doesn't the "yes/no" bit fit human thought better than the "up/down/left/right" qubit?

But that is off topic...
