CONCEPT
Mechanical Evolution
Clarke's framing of artificial intelligence as the next phase of evolution — a process "thousands of times swifter" than the biological kind, operating on a different substrate but continuous with the same trajectory.
Mechanical evolution is the conceptual frame in which AI is understood not as a tool humans build but as a successor process to biological evolution — a system that, once underway, exhibits the same dynamics of variation, selection, and accumulating capability that produced the human nervous system, accelerated by orders of magnitude because the substrate (silicon, software, training data) is more malleable than DNA. Clarke advanced the framing in essays of the 1960s; it has been picked up since by Vinge (the singularity), Kurzweil (accelerating returns), Tegmark (the spectrum of agency), and Anthropic's own conceptual writing on AI as a self-improving process. The frame has predictive content and ethical content; both are contested.

The predictive content of the mechanical-evolution frame is that improvements in AI capability will compound across generations of models in a way that resembles biological evolution's compounding across generations of organisms, but on the timescales of model-training cycles rather
