Jim talks with Antony Valentini about the difficulties of interpretation of quantum mechanics in light of quantum gravity.  In particular, Antony discusses the failure of the Born Rule due to the impossibility of normalization (the fact that probabilities must sum to 100%) at that scale, and therefore the need to interpret the wavefunction as something more than merely the knowledge of the observer about the system.  They spend some time talking about the de Broglie-Bohm interpretation in light of quantum gravity.
