> communication costs dwarf almost every other cost.

That may have been true 10 or 20 years ago when networking was much slower.

[bunderbunder]

Everything else was much slower, too.

Oftentimes the biggest cost associated with communication is latency, and the one thing that hasn't changed over the past few decades is the speed of light.

The problem usually isn't so much throughput, it's latency... and the speed of light sets a lower bound on that, unfortunately.

its still true because everything else is faster, too
