The Short Version
The evidence supports that classical transistor-density doubling has slowed significantly and become less predictable, but it does not support the claim that Moore's Law has "effectively ended" as of March 2026. Multiple authoritative 2026 sources — including imec, TechInsights, and industry roadmaps — describe ongoing 2nm-era scaling and characterize the trend as evolving or transforming rather than terminated. The claim overstates a real slowdown into a definitive, time-stamped conclusion that the available evidence does not warrant.
