Indeed. That's one of the few things that one can say has nothing to do with either the original Hyperloop alpha concept or the new college competition entries. Pneumatic tubes mean that they make use of pressure to push things - that's what the word "pneumatic" means. Pressure being the one thing Hyperloop (all permutations) distinctly lacks.
The lecture didn't cover anything newer than Hawking Radiation. Where's the discussion over the Firewall Paradox?
Anyway, my preferred hypothesis: singularities don't exist, crossable event horizons don't exist, there is no disjoint region of spacetime beyond them, there is no unusual quantum behavior, localized inflation maintains a continuous spacetime metric at black holes by deforming infalling partial motions to a tangential path, matter/energy that falls into a black hole is as thoroughly fried and scrambled as they would be falling into such an extreme environment even if spacetime deformation weren't an issue, but the result is nearly frozen in time, released as the black hole explodes in an inflationary blast - and the Big Bang was a colossal such event.
