According to Prof. Hoffman, this model of the universe is highly parsimonious in that it can model data from the Large Hadron Collider using a single parameter, while the best incumbent (Quantum Field Theory) needs millions.
The implication is that everything we see and experience are not fundamental, including space and time itself. The fundamental unit of reality is consciousness.
This has far reaching implications into every other scientific and non-scientific human endeavor, from neuroscience to philosophy. It's no exaggeration to say that if he's right (and he claims the math shows that he is) it may be the most important discovery in human history.
Even Albert Einstein appears to have intuited this when he wrote:
"Time and space are modes by which we think and not conditions in which we live."
As for that lack of a falsifiable claim, agree, not only that, but one that would allow for a preponderance of evidence.
Donald Hoffman was interviewed and topic of falsifiable observations came up and as far as I am able to tell he avoided the topic; search for “falsifiable” in this link:
It's a good question, and as a layman I don't have the answer. However, since it's able to model experiments in the Large Hadron Collider, I would assume that it makes predictions about the positions and velocities of high energy particles.
In any case, Dr. Hoffman's theories are mathematically rigorous. I think it's worth listening to the podcast before dismissing.

I can't really comment on that as 1) I only skimmed a couple sections of the paper and 2) my field is more applied math than pure. I'm not attacking or dismissing anything, just asking how the claims made are substantiated.

Do those models cover experiments which have yet to be run, and more importantly are they predictions which differ from those of the standard model?
There are a lot of neat theories which model experimental work we already have results for, the problem is using said theories to make falsifiable predictions which are both realistic in terms of actually finding a way to do experimental verification and are different from predictions made by the standard model. Nobody really loves the state of physics as-is, but moving on to something else requires meeting those two conditions which has been an insurmountable hurdle as of yet.

Ideally yes. But if you have two theories which make the same predictions, and one requires orders of magnitude fewer parameters than the other, then the former is, if nothing else, a valuable new perspective.
The analogy that comes to mind is the elaborate system of epicycles in the geocentric model of the solar system. These were quite accurate -- even more accurate than the first heliocentric model (if I recall correctly). But the heliocentric model was far simpler in that it required fewer parameters (and as we know it turned out to be the correct one).
It's still early days for the cosmological polytope. It's right to be skeptical, but the greatest scientific advances are usually considered ludicrous at first by the broader community. It's those who allow for the possibility that the new theory may be correct that will design and carry out experiments to provide evidence either way.
Yes, that's exactly my question too. "Consciousness" is often ill-defined for experimental purposes and notorious for being abused through vague "deep-ities" to make unsupported assertions about "the meaning of everything."
