Vacuum tubes → transistors → integrated circuits → microprocessors → today
In the 1950s, computers switched from vacuum tubes to transistors, becoming:
– 10× faster
– 50× smaller
– 50× cheaper
Just four years later, integrated circuits leveled things up again.
~13 years after that, microprocessors scaled it all down to a single chip, laying the foundation for modern computing.
⚛️ Quantum computing is now at that same vacuum-to-transistor stage -- paving the way toward a future we might not even be able to imagine.
