Could you elaborate what's wrong with that idea?

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.

'Collapsing the wave function' is now generally thought of as a result of entanglement between the measurement device and the system that's being observed rather than some magical quality of consciousness.

But any measurement device always has a conscious observer that reads in one or another way results of measurements (e.g. spin directed up or down) from this device. Without such observer a combined system of the device and the quantum system of interest would infinitely be in a state of superposition.

You're just another measurement device that's entangled with the system at that point, though.
