Per the footnotes at the bottom this builds on the work of Hardy a few years ago, who demonstrated that QM could easily have been derived by Victorian era mathematicians as a generalization of probability theory available at the time.

While not everything in the book is perfect, it also reminds me of Penrose's Road to Reality, which painstakingly takes the question "what is a number?" to build up a sophisticated understanding of what that means and then explains how this impacts Physics in a very real way.

We've made so many advances in recent decades we sometimes forget to step back and reformulate our teaching methodologies to incorporate what we know, simplify the teaching, and make the ideas more accessible earlier, so we can put more minds to work on extending them. That's a shame.
