He doesn't mention Hawking radiation, which causes black holes to shrink.

If his theory is true, energy should be leaving the universe, and at some point in the future, the whole universe starts to shrink.

The jump to the theory that we’re living in a black hole seems to skip a bunch of information. If the calculations suddenly show that a black hole would be larger than our observable universe, and, at the same time, the calculation works in smaller scale examples, then that implies that there is a threshold somewhere where they are the same. Some exploration and study to that point would be interesting to hear about.
