Nah you are very correct, I just feel that our compilers can still do a better job with the general purpose code because they are usually completely blind to the systems the compiled code runs in (as in, I/O takes orders of magnitude more time for example and this can be used to auto-parallelize code; but I know compiler authors will never auto-spawn threads). I feel this can be improved a lot but for various (and likely good) reasons our tooling is not as good as it can be.

Good points. I wish I knew more about compilers sometimes, and this is one of those times.
