  Room temperature superconductivity has been the most prominent, highly
ambitious, but still imaginable, acme of materials physics for half a century.
The struggle toward this revolution was foreshadowed by a Victorian novelist
and championed,unsuccessfully, by dogged physicists in the 1960s to 1980s who
had a workable theory but uncompliant materials. Discovery of superconductivity
of H$_3$S at 200 K in the 160-200 GPa pressure range has renewed anticipation
of yet higher values of the critical temperature T$_c$. With the several
reports of metalization of hydrogen, and theoretical extensions enabled by
modern algorithms and unprecedented computational hardware and spurred forward
by the Materials Genome Initiative, it is possible that the room temperature
precipice has thereby already been breached in a silent revolution. This
concise note draws analogies of this development with an earlier revolution.
