Thomas Edison’s filament‑bulb demonstration took place on the streets of New Jersey in **1879**, launching the Second Industrial Revolution.

Steve Jobs’s iPhone demonstration in **2007** started the mobile revolution.

Elon Musk’s Roadster demonstration was noted as potentially starting the “Jetsons revolution?”.

I reflected on these demos, downgrading Doug Englebart’s 1968 demo as more subservient to the broader computing and mobile platform revolutions.
