After sixty years of devoted service, Moore's Law will die a dignified death no later than the year 2019. By that time, transistor features will be just a few atoms in width, and the strategy of ever finer photolithography will have run its course.

Ray Kurzweil

The Law of Accelerating Returns

Annotation

Kurzweil was roughly right that traditional scaling would hit physical limits around this period — Dennard scaling broke down in 2006, ending the era of automatic clock-speed increases — but Moore's Law in the strict transistor-density sense proved more stubborn than expected. TSMC shipped 5nm chips in 2020 and 3nm in 2022, and Apple's M2 Ultra packed 134 billion transistors onto a single die. The 'dignified death' turned out to be a long, inventive hospice of FinFETs, gate-all-around architectures, and chiplet packaging.

What Actually Happened

Moore's Law did not die by 2019. Dennard scaling broke down in 2006, ending automatic clock-speed increases, but transistor density continued advancing through FinFETs, extreme ultraviolet lithography, and gate-all-around architectures. TSMC shipped 5nm chips in 2020 and 3nm in 2022. Apple's M2 Ultra packed 134 billion transistors onto a single die. The semiconductor industry kept finding engineering workarounds that extended density scaling well past Kurzweil's deadline.

Why did I pick on the next nine years instead of the next 900 for finding a solution to the population crisis? One answer is that the world is rapidly running out of food. And famine, of course, could be one way to reach a death rate solution to the population problem. In fact, the battle to feed humanity is already lost, in the sense that we will not be able to prevent large famines in the next decade or so.

At present weapons are being changed every ten years, and even more frequently. In another fifteen years or so, people will use for shooting not rifles but some kind of lightning, some sort of a machine emitting a holocaustal electrical stream. Tell me: what can we invent in this line so as to surprise our neighbors? What if in fifteen years every great power will have secretly stored away one such surprise for any kind of eventuality? Alas, we are merely capable of imitating and purchasing ammunition from others, and—at best—of repairing it at home. To invent such machines we should have to have our own independent, and not purchased, science, not an imported but a free one—one that has taken root in our soil. As yet we do not possess such a science, nor do we even have a purchased one.
