Regarding love of complexity and C++, they’re sitting on the C++ committee. Complexity is their bread and butter. :)
I also kinda doubt “Trillion dollar ultra low latency / high throughput high frequency trading/AAA+ games running on 4 x 4k monitors at 200+ fps” people are such enthusiasts of the bleeding-edge of C++. The standard library and the style of programming popular in the committee isn’t very concerned with high performance it seems.
