It's not even really true for theoretical science. Most of physics (materials, condensed matter, etc.) doesn't function by producing a few huge discoveries that leave everyone else with nothing to do. Most of physics discovery is incremental in nature.
Negative index metamaterials, giant magnetoresistance, high temperature superconductivity. . . these things created tremendous numbers of jobs in their areas, many including permanent positions.
Even Einstein doesn't really demonstrate this stuff about the second Einstein effect. In many cases - special relativity, brownian motion, Bose-Einstein condensates, possibly even general relativity - Einstein was
the "second Einstein".
It's complete nonsense that has no basis in fact.
