Sure a fully solid state box where only photons and electrons do move
is highly desirable, but heat dissipation issues and the sorry state
of nonvolatile memory (rotating bits) require forceful movement of
cooling medium and translation of dumb but cheap storage past smart
but expensive reader contraptions. Mercury delay lines, hard drives,
photonic storage media, it's all the same.

When magnetic storage will saturate, we'll move on to manipulative
proximal probe, and then, hopefully, to purely solid state storage and
computation, all components being molecular.
