I wanna see this guys awesome contribution to software in code. We all know and have seen Carmacks code in public. What has this guy written in public. If his master piece is closed source, better not to put him on a pedestal.
I dont really partake in programming "wars", but the idea of launching a set of separate processes instead of separate threads to do a bunch of IOs has always seem to be weird to me. Yes, I have built software using Python. Yes, I have done things as you suggest. Now I use asyncio, since the syntax has matured and I finally understand coroutines, runners, tasks etc. Lets see where the GIL less Python takes us.
