Demis Hassabis explores the surprising tractability of seemingly intractable natural phenomena for classical learning systems, arguing that evolutionary and physical selection processes carve low-dimensional manifolds within vast combinatorial spaces. From protein folding to fluid dynamics, once-impossible tasks are yielding to neural networks that reverse-engineer structure from data, suggesting that “anything that can evolve can be efficiently modeled.” This conjecture reframes complexity theory, proposing a new class of Learnable Natural Systems and reviving the P vs NP debate as a question about the informational structure of reality itself.



Hassabis recounts how DeepMind’s Alpha lineage—Go, Fold, Genome—demonstrates that smart modeling plus guided search can tame problems with state spaces larger than the universe, pointing toward polynomial-time solutions on classical hardware. He envisions similar approaches cracking weather, cellular automata, and even emergent phenomena, provided we can formalize the objective functions and exploit hidden gradients. The same paradigm underlies VO3’s uncanny ability to render liquids and lighting by learning intuitive physics from passive video, challenging the need for embodied interaction and hinting that world-models can arise from observation alone.



Looking ahead, Hassabis dreams of simulating a complete yeast cell, layering AlphaFold’s static structures with AlphaFold3’s dynamic interactions to span multiple timescales, then scaling to human cells and the origin of life itself. He foresees AI-generated open-world games where players co-create infinite narratives in real time, and post-AGI sabbaticals devoted to such creative pursuits. Throughout, he stresses the fusion of rigorous science, artistic taste, and humanist values needed to steward transformative technologies responsibly while expanding the boundaries of what can be understood, modeled, and ultimately lived.
