Hopefully people are buying what they need to solve their problems.
Sometimes that means you need a relatively expensive interconnect.
That also means that you end up buying a more expensive node.
Sometimes that means you don't have all the space in the world, so
buying 40 cheap machines instead of 10 more expensive ones is a no-no.

That would be just as meaningless as the current top500. Why? Because
our object in life is to get our work done within our constraints, not
to get the highest GFLOPS/$.
