I love these words "As I continued that work, I've also started talking about the feasibility of creating a supercompiler." and thoughts already.

One of my ideas is a supercomputer compiler

I wrote about it here

Application performance monitoring, scheduling, control loops ala Kubernetes, parallelism, multithreading, data scheduling (shifting and sharing data to where it needs to be used), advanced caching and regeneration and container scheduling and binpacking and data layout scheduling could all be compiled by a supercompiler for extreme performance.
