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.
