That is kinda my point though. None of those are kernels, device drivers, hypervisors, virtual machines, interrupt handlers, bootloaders, dynamic linkers; and writing such things in Go would be an uphill battle against the language's own design, much like the Go runtime itself. Being a GC'd language almost completely fences Go off from even being in the running for these, except for hobby projects trying to prove a point.

Universal applicability may not be necessary to write a Ruby installer, but it certainly is to have any hope of taking C's crown.
