Betting on Moore's law to speed up your software hasn't held for more than a decade. Software keeps getting worse and hardware has largely plateau'd in what you can expect to get in single threaded performance. And besides, running a CPU for 2-5x as long to accomplish the same task is wasteful in both time and energy, both of which are scarce resources. Especially for something that is done as many times as rebuilding the Linux kernel.
