2040 — 2050
Post-silicon computing, molecular manufacturing, human longevity extension, and intelligence explosion scenarios.
Speculative. Based on extrapolation of current research trajectories, expert consensus, and technology roadmaps. Actual outcomes may diverge significantly.
~2040–2045
Post-Silicon Computing Architectures
Silicon transistor scaling reaches fundamental physical limits. Neuromorphic chips, optical computing, carbon nanotube transistors, and 2D material (graphene, MoS2) devices begin replacing silicon in leading-edge applications.
~2043
Molecular Manufacturing Prototype
Nanoscale assemblers capable of arranging individual atoms into functional structures demonstrated in laboratory conditions. Feynman's 1959 "plenty of room at the bottom" becomes engineering reality.
~2045
Human Longevity: Biological Age Reversal in Trials
Senolytics, epigenetic reprogramming, and AI-designed therapeutics begin demonstrating measurable biological age reversal in human clinical trials. Life expectancy projections begin to be revised upward materially.
~2045–2050
Intelligence Explosion Scenarios
If AGI is achieved by ~2035 and can recursively improve its own design, the resulting acceleration of AI capability could make all previous technology forecasting irrelevant. The 2040s may look as different from today as today looks from 1850.
