Are you kidding me? This is pretty fucking arrogant. My $DAYJOB is FreeBSD kernel hacking.

Reusable piped programs are great for some things, especially a productive shell language. No, composing processes is not great for all things, and certainly not where performance is required. This is why FreeBSD is a monolithic kernel instead of a microkernel with processes, for example.

Spawning a program is incredibly slow, even ignoring disk read times, compared to 3 levels of low-branch-factor search in any language.
