The Great Chain of Technology
Why are these inventions connected? Each solved problems created by the previous generation. Printing press needed distribution → Steam engine provided power → Telephone needed wiring → Light bulb enabled evening work → Airplane enabled travel → Penicillin healed injuries → Transistor enabled computation → Internet connected computers → Smartphone made it portable → CRISPR makes us masters of genetics. This isn't a random list—it's the story of civilisation.
