That's exactly the sentence that made me pause. I could hook up an implementation of Conway's Game of Life to a Geiger counter near a radioisotope that randomly flipped squares based on detection events, and I think I'd have a non-algorithmic simulated universe. And I doubt any observer in that universe would be able to construct a coherent theory about why some squares seemingly randomly flip using only their own observations; you'd need to understand the underlying mechanics of the universe's implementation, how radioactive decay works for one, and those just wouldn't be available in-universe, the concept itself is inaccessible.

Makes me question the editors if the abstract can get away with that kind of claim. I've never heard of the Journal of Holography Applications in Physics, maybe they're just eager for splashy papers.
