Wisdom in fragments

While a quantum computer could certainly cause significant economic and social disruption if used to break encryption, it does not pose the same kind of direct, physical threat to humanity as nuclear weapons. The situation is somewhat mitigated by the existence of quantum-resistant or post-quantum cryptographic schemes.

Having recently spent two years working on AI safety and ethics at OpenAI, I have been deeply engaged in examining the moral and societal implications of artificial intelligence. With AI, we face a profound civilizational question: as AI systems become increasingly capable of performing tasks previously done by humans, what role will humans play in an AI-driven world?

My initial motivation for studying quantum computing was a desire to understand the fundamental computational limits of the universe. Even in the absence of practical applications, I believed this pursuit was worthwhile as the most rigorous test of quantum mechanics to date. In fact, I often joke that disproving quantum computing sceptics is the primary application of a quantum computer, with everything else being a bonus.

The strangeness of reality was apparent long before the advent of quantum mechanics. The history of science is a sequence of revelations, each showing that the true nature of things is not what it seems to the casual observer. Quantum mechanics, however, takes this weirdness to a new level.

A quantum computer is very similar to a classical computer, with one key difference: it takes full advantage of the laws of quantum mechanics. The heart of quantum mechanics is the concept of amplitudes. An amplitude is a new kind of number, related to but distinct from an ordinary probability. Amplitudes can be positive, negative, or even complex numbers.

Start doing things not for the end product, but for the impact on your heart, your brain, your life, and your health. Recognize that you've been conditioned to hate yourself and your creativity for the sake of a culture that does not care about you.

Look at Jeff Bezos telling his 1.5 million employees to 'wake up every morning terrified and stay terrified all day.' They're not getting rich; they're barely scraping by. Yet he wants them living in terror so he can get even richer. That's crazy. That's a crazy society and a crazy life.

As far back as we know, humans have spent a lot of energy making what I call 'pointless, precious things.' Archaeologists recently uncovered a life-size sculpture of a bison, 14,000 years old, in a cave in France. That must have taken real effort by people likely living a Palaeolithic lifestyle. That's part of why we've been so dominant on this planet.

In the 1960s, NASA commissioned a study to identify creative geniuses for hiring, and found that 2% of the adults they tested fit the bill. A few years later, someone thought to give the same test to four- and five-year-olds—and 98% of them qualified as creative geniuses. The researchers blamed the school system.

Fear is like being shot out of a cannon. Imagine a car has fallen on someone I love—I get this clear, calm, intense bolt of energy. In that heightened state, I could lift the car off them (as has happened before in rare cases). Anxiety, on the other hand, is like being haunted. You never actually see what's scaring you—it's just a story in your head that never goes away.

Einstein famously said time is what a clock measures, which was a half-joke but also the best answer he could give. A clock measures the 'distance' it travels through spacetime between events. That's fascinating, but it still doesn't tell you what time actually is.

Quantum mechanics is a consistent mathematical structure, not that difficult to understand in itself, which nature has chosen. The confusing thing is that nature chose something that doesn't feel intuitive to us. It has a reputation for being mystifying mainly because of its history rather than what it really is as a theory.

Many biologists I speak to would say it's almost incomprehensible that something as complex as us has even appeared at all—we might just be very lucky. Or maybe it normally only takes a few hundred million years to go from life to intelligence, and we were just slow. We have a sample size of one.

The paradox is that in the Milky Way galaxy, with something like 400 billion stars and trillions of planets, it's estimated there may be around 10 billion potentially Earth-like worlds. And the galaxy has been around for about 13 billion years. If a civilisation had developed ahead of us and become spacefaring, it's very hard to see why we haven't noticed any evidence of that.

Whatever you think it is, it self-evidently exists, because the universe means something to each of us. But I would argue that whatever it is, it's an emergent property. So it exists here on Earth because there are complex biological systems. Without those complex biological systems, it doesn't exist. There is no meaning. We bring meaning to it.

These scorecards just lead us down a path of dissatisfaction, when in reality most things that truly matter for happiness can't be measured in any meaningful way. We should be more mindful of living in the moment rather than keeping tally marks that don't really serve us.
