This quote by Carver Mead struck me as pretty relevant to thinking about the fulcrum that is forming before us:
"The quantum world is a world of waves, not particles. So we have to think of electron waves and proton waves and so on.
Matter is 'incoherent' when all its waves have a different wavelength, implying a different momentum.
On the other hand, if you take a pure quantum system - the electrons in a superconducting magnet, or the atoms in a laser - they are all in phase with one another, and they demonstrate the wave nature of matter on a large scale.
Then you can see quite visibly what matter is down at its heart."
