2030 — 2040
Fault-tolerant quantum, physical AI, nuclear fusion first light, and the AGI inflection point.
Best estimates. This decade will likely see the most disruptive technology shifts since the invention of electricity. Specific dates carry ±3 year uncertainty.
Milestones
~2032
First Fault-Tolerant Quantum Computer
A quantum computer with sufficient logical qubits to run Shor's algorithm on commercially relevant key sizes. RSA-2048 at risk. Post-quantum cryptography migration becomes critical infrastructure.
~2033–2035
Nuclear Fusion Net Energy Gain at Commercial Scale
Following NIF's 2022 ignition demonstration, private fusion companies (Commonwealth Fusion, TAE, Helion) targeting commercial pilot plants. First grid-connected fusion power by mid-decade best case.
~2035
AGI Debate Becomes Empirical
AI systems capable of matching human performance across virtually all cognitive tasks. Whether this constitutes "AGI" depends on definition, but economic and labour market impacts will be unambiguous and large.
~2035–2038
Brain-Computer Interfaces Go Consumer
Following Neuralink's medical trials, non-invasive BCI devices reach consumer markets for augmented cognition, gaming, and accessibility applications.
~2040
AI Designs Next-Generation Chips Autonomously
AI chip design tools advance to the point where the next node's architecture, physical design, and verification are completed primarily by AI systems with minimal human intervention.
