Semiconductor
Semiconductors are not magic — they’re doped crystals whose usefulness begins and ends at the p–n junction.

Laser
Theodore Maiman · 1960
Theodore Maiman’s 1960 laser is a milestone in quantum electronics—not because it launched applications, but because it proved coherence could be engineered in a solid, at room temperature, using flashlamp excitation. Its limitations are structural: three-level pumping demands high peak power and prevents continuous operation. Its success lies in specificity: 694 nm, pulsed, ruby, May 16, Malibu.

Amiga 500
Commodore · 1987
The Amiga 500 is a pivotal hardware milestone—not because it introduced new silicon, but because it delivered proven multitasking and colour graphics to mainstream retail at a time when competitors treated those features as optional or impossible in home systems. Its success relied on reuse, repackaging, and distribution—not invention.

BBC Micro
Acorn Computers · 1981
The BBC Micro was a procurement win first, an educational tool second. It succeeded because it met rigid broadcast and policy constraints—not because it was inherently superior to alternatives. Its architecture prioritised demonstrable compliance over user flexibility. Its dominance was guaranteed by subsidy rules, not market preference.

VR stops needing a room—and starts needing a compromise.
