Computers are inherently asynchronous, we just plaster over that with synchronous interfaces. We put a lot of effort into maintaining these synchronous facades - from superscalar CPUs translating assembly instructions into “actual” instructions and speculatively executing them in parallel to prevent stalls, to the kernel with preemptive scheduling, threads and their IO interfaces, right up to user-space and the APIs they provide on top of all this. Surely there has to be a better way? It seems ridiculous.
