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.
