Building with non deterministic systems isnt new. It does not take a scientist. Though people who have experience with these systems are fewer in number today. You saw the same thing with TCP/IP development where we ended up developing systems that assumed the randomness and made sure that isnt passed on to the next layer. For every game, given the latency involved in previous networks, there is no way on the network games were deterministic.

Isn't any kind of human in the loop make system non-deterministic?
