Non-existence doesn't exist within existence. The parasitic few who suggest "Tesla" shaped it by choice of reaction out of ALL existence, and each ONE who doesn't just consent to the suggested idol "Tesla", can use it as inspiration to shape comprehension about ALL perceived. We all perceive the same reality; the parasites use suggested words (idolized meaning) to deceive us to ignore reality for suggested fiction.

Resist the temptation to believe vs not believe (reason) the suggested his-story of Nikola Tesla and instead try to be inspired by how the few use words to describe functions of movement; while trying to hide the movement from those they suggest the descriptions to. Their only trick is to invert movement by suggesting affixed meaning, so that we think about affixed meaning instead of adapting to ongoing movement (inception towards death) by choice of reaction.

Tesla existed and is responsible for much of the modern world. Building on the work of Faraday he pushed alternating current pretty much to it's limits. He was utterly wrong about the free energy thing though. That stuff is impossible for reasons of geometry and market forces.
