Gordon Moore

Gordon Moore (1929–2023) was the quiet chemist of Silicon Valley — the calm one in every room full of brilliant egos, the man everyone trusted — who once, when a trade magazine asked him to predict the future of electronics, drew a line through four data points and accidentally wrote the operating manual for the next half-century of civilisation.

Four dots and a ruler

In 1965 Electronics magazine asked Moore, then head of R&D at Fairchild, for a puff piece on where chips were headed. He plotted the number of components on a chip against the year — he had all of four points — and noticed it was doubling every year. So he extrapolated the line a cheeky ten years out and predicted 65,000 components per chip by 1975, plus home computers, "personal portable communications equipment", and cars full of electronics. In 1975 he revised the doubling to about every two years, and his friend Carver Mead gave the observation its name: Moore's law.

Here's the delicious part: Moore's law isn't a law of physics — it's a self-fulfilling prophecy. Once everyone believed the industry doubled density every two years, every company had to plan for it: fabs were financed, tools ordered, and products roadmapped against the line, because falling behind the "law" meant being lapped by whoever kept up. A casual trade-article extrapolation became the semiconductor industry's shared metronome and capital-allocation schedule for five decades. Moore himself found the fuss bemusing — he said he mainly wanted to get across that chips were the route to cheap electronics.

The calm half of Intel

Moore was one of the "traitorous eight" who walked out of William Shockley's lab in 1957 to found Fairchild — characteristically, the least dramatic walker-out — and in 1968 he and Robert Noyce left again to start Intel. Noyce was the charismatic mayor; Moore was the steady long-range navigator who decided which technology bets to make, memory then microprocessors, each timed against his own curve. He also coined the less famous Moore's second law: the cost of a chip factory doubles too. He was right about that one as well — a leading-edge fab now runs past $20 billion, which is why so few companies still own one.

The fisherman's ending

Moore never acquired the billionaire lifestyle that his stock certificates suggested; his great extravagance was fishing, which he pursued on rivers from California to Alaska with the same patience he applied to silicon. With his wife Betty he gave away more than $5 billion — to basic science, to astronomy (the Thirty Meter Telescope), and above all to conservation, protecting rivers and forests on a scale to match the industry he'd helped build. It's a fitting final graph: the man who taught the world exponential growth spent his last decades investing in the things that shouldn't have to double — quiet water, old trees, and time to think.
