2, I’m also interested in they why for the underlying performace of the sort method: it takes more than 100 ns per element, which means 100s of CPU clock cycles and usually even more instructions than that (on a superscalar processor)! As a sanity check, a quick benchmark ( perf record ./bench && perf report) shows that more than 90% of the time spent in this approach is in the sorting routine, qsort - so we are right to focus on this step, rather than say the de-duplication step or the init...

Specifically, my side of the bet was, "Virtual reality hardware (not counting cardboard) will not sell more than 10M units/year worldwide before March 2019." He bet that it would. In early 2020, we decided to wait settle the bet because it looked like there was some chance VR would reach 10M units/year in 202...
