There was a debate about what to call the quantity and he ended up using the term "entropy" due to the mathematical similarity, but later I think he regretted that choice because the relationship with physical entropy more form than anything else and it leads to some misleading analogies.
Apologies, since I think I skidded off the right brain topic, and whether it's chaos or luck or serendipity I like it.
