In context, I'm pretty sure it was just saying "Unlike computation, bandwidth, and memory size, we haven't seen much improvement in latency, and even if we focused on it, we have a very clear limit we can't get past".

I.e., latency is -always- going to be an issue, for everyone doing anything distributed; it will never go away, or become so small as to effectively be ignorable. You can trim the fat, which can improve the real-world experience of certain things, but it doesn't actually solve, or even simplify, the hard edge cases. It just may make them rarer.

The idea that latency is currently bounded by the speed of light is what stops people from fixing the fact that it is not. This is my objection.

What is the upper bound on latency?

Stating the problem might provoke people to work on fixing it?
