My youtube review of Lenny Susskind's excellent video lecture on the world as a hologram

The question Lenny should have asked in that lecture is whether we are 3D images whose information is scrambled all over our past and future 2D horizons relative to observers outside them in the multiverse?

Lenny is a very clear and good teacher. We worked together at Cornell with Johnny Glogower in the early 1960's on the problem of time and coherent phase of oscillators in quantum theory. The lecture is excellent and clearly explains important cutting edge ideas. I do have a number of comments below.

1) alleged first law of physics (technically unitarity of the S-Matrix) that the total number of bits is conserved. Is this really consistent with the second law of thermodynamics that the entropy of a closed system generally increases? Is it consistent with the evolution of complexity of matter including life and knowledge as the universe expands? The universe was very small at the moment of inflation followed by the hot big bang. Are all the bits we see today already hidden in the big bang?

With the emergence of new order as in spontaneous symmetry breaking of the vacuum for virtual particles and the ground states of real many-particle complex systems - is the S-Matrix fundamentally non-unitary? At least the question needs to be asked and made conscious. Lenny's description of horizon thermodynamics & complementarity is excellent - how Alice's bits get scrambled all over the black hole horizon as seen by Bob far away from her. Bob's light will burn up her if he tries to look etc.

We are outside black holes, but we are inside our cosmological horizons. Lenny only talks about our observer-dependent past particle horizon. That's half the story. Tamara Davis shows that we also have a future event horizon and that the Hubble sphere where expansion rate is c is different from both horizons. Wheeler-Feynman-Hoyle-Narlikar­-Cramer-Aharonov all show that the future absorptions of light are loops in time with the past emissions.

Dark energy accelerating our universe may be advanced back-from-the-future Hawking radiation emissions from our future de Sitter horizon of energy density hc/Lp^4 that is gravitationally redshifted down to hc/Lp^2A where A is the area of our future horizon at its intersection with our future light cone. The competing cosmological blue shift is tiny at z = 1/2 compared to the advanced gravity redshift of z ~ A^1/4/Lp^1/2 ~ 10^30.5
