The foundation of our electric grid is based on aether theory. Had Tesla and Steinmetz subscribed to quantum theory, they would have never made these breakthroughs.

The discovery of electricity, which is modelled as a single unit in conventional (modern) physics rather than a hybrid of magnetism and dielectricity, is literally what underpins lasers and computers, since they could not exist without discovering electricity. Lasers are phase coherent, point source light. Nothing to do with "quantum". Qubits are a conventional description of superposition of states as opposed to binary bits, using particle physics as the foundation. Or, within an aether framework, simply, waves. This is why people can't wrap their heads around the dual slit experiment; their minds are infected with the idea of particles rather than phase interference of waves, so this is explained in the form of a duality rather than the obvious answer.

Atomic clocks work by monitoring resonant frequency. Aether physics posits that there are no particles, only waves. Therefore the physics of atomic clocks is still consistent within an aether framework.

Aether physics was discarded because of the uncomfortable results that would have invalidated these modern theories from michelson-morley and michelson-gail-pearson, in that the aether was detected and moving using interferometric measurements. Tesla rejected the theory of electrons and general relativity, and by his own admission, Einstein didn't operate on the same level as Tesla. The "fuzzy haired crackpot" gave the world nothing but theories, whereas Tesla and Steinmetz gave the world the AC motor on the basis of an aether as the foundation for their work.

Indeed, the insanity of particle physics and quantum (literally quanta, or quantity, trying to quantify that which cannot be quantified) has resulted in most people trying to understand the world through a framework that is illogical at its core.
