Clearly this is true. However, while the benefits of o/s effort are down
on top end hardware, one of the strengths of Linux is that it runs well on
small, or embedded, or old, or totally obsolete hardware. So there is a PR
and social benefit from the efforts already invested in making the code
use the hardware carefully.
