Can you describe one moment when physics challenged or confirmed your metaphysical beliefs? What did this experience teach you about the limits or possibilities of either field?

Back when I was starting at DeepMind, I was working on quantum algorithms and saw classical uncertainty turn into quantum probability. That was weird. I had to accept reality can be blurry at its core, not because we just don't know things. Physics won out, my intuition was useless. The rules underneath are stranger than any story I could believe.

So I'm building these AI health tools, and it's interesting. The biomarker data follows physics so closely, which makes me trust our models are solid. But then you get this weird anomaly that reminds you the body still has secrets. Physics gives us the rules, but the unexpected keeps happening. You have to respect both. That's the only way things actually move forward.
