Another way to look at it : if an "AI" can predict what you would code next, it means your program is probably not that innovative, and was already created somewhere.
1. In distributed computing, there are usually minimal communication because nodes communication is costly, the bottleneck can still be the hot loop on each nodes.
2. When optimizing the hot loop only, it can be quickly written in Cython or C, since the scope is usually a lot smaller, so no need to use Go.
