This feels like the kind of popsci that's written for people who already agree with the author - there's nothing resembling an argument, or even a definition of "computation." There are nods to Church-Turing, but the leap from "every effectively calculable function is computable" to "life is a computation" is larger than anything you could fit in a book.

I felt reminded of Hofstadter's Goedel/Escher/Bach mysticism that somehow everything is recursion.

I might not be a strange loop but I am indeed strange.

or the idea that the universe is a computer

In any case, he did fit that into a book! If only barely.

Edit: On further reflection, I suppose he didn't, if we consider the effort to span Gödel Escher Bach and I Am a Strange Loop.
