Moore’s observation

1965

In 1965 Gordon Moore noted that the number of components on a chip had doubled on a short cycle and guessed it might continue. It was a forecast, a coordinating myth, and a business plan — not a law of nature. For decades the industry used it as a schedule: shrink, yield, sell. When physics got hard, the doubling slowed. Treat it as history, not destiny.

How the mechanism is arranged

An observation, not a law of nature: transistor counts on a chip doubled on a roughly two-year cadence for decades.

How it works

Shrink transistor features with better lithography and device design.
Raise yield so more chips per wafer are good.
Sell the extra transistors as new products, funding the next shrink.

Why it mattered

Gave electronics a shared roadmap.
Made exponential language ordinary in a factory.
Hid, for a time, that exponential curves end.
