  Could it be that the matter from the electrons in high Tc superconductors is
of a radically new kind that may be called "many body entangled compressible
quantum matter"? Much of this text is intended as an easy to read tutorial,
explaining recent theoretical advances that have been unfolding at the cross
roads of condensed matter- and string theory, black hole physics as well as
quantum information theory. These developments suggest that the physics of such
matter may be governed by surprisingly simple principles. My real objective is
to present an experimental strategy to test critically whether these principles
are actually at work, revolving around the famous linear resistivity
characterizing the strange metal phase. The theory suggests a very simple
explanation of this "unreasonably simple" behavior that is actually directly
linked to remarkable results from the study of the quark gluon plasma formed at
the heavy ion colliders: the "fast hydrodynamization" and the "minimal
viscosity". This leads to high quality predictions for experiment: the momentum
relaxation rate governing the resistivity relates directly to the electronic
entropy, while at low temperatures the electron fluid should become unviscous
to a degree that turbulent flows can develop even on the nanometre scale.
