Some of that is sort of nonsensical (like the idea that observation creates reality)
As far as I could understand he just talks from psi-empistemic point of view about wave function collapse. Although now we don't have any way to determine whether psi-epistemic or psi-ontic point of view is 'correct' (as like as define what precisely does mean 'correct' for this question), I don't think that you can just call one of these views nonsensical, especially without support arguments.
