In addition to the paper and Twitter thread mentioned by fasteo elsewhere on this thread[a], this video of a lecture by the author is well-worth watching too:
Among other things, in this lecture the author shows, step by step, in non-technical language, an example with coin tosses in which changes in wealth are non-ergodic (in the sense he explains), such that the expected value of winnings over time is not informative of the time average growth rate of wealth.
