Exactly. This is why low bandwidth, high latency memory and communications is not the problem, but the *solution*. Together with caches and changed software assumptions, of course.

Declaring the solution to in fact be the problem and vowing to do away with it just leaves you holding the bigger problem. Handwaving about "streaming" or "optical" does not solve the problem. People need something that works now.
