Dreaming introduces noise into our system. There's a compelling hypothesis in machine learning called 'overfitting,' where systems become so tuned to recognizing patterns that they falter when faced with new, unexpected scenarios. Some computer scientists are exploring ways to inject noise into computational models to keep them adaptable.

Paying a negative interest rate on currency, or on electronic reserves at the central bank, may seem barbaric to some... But it is arguably no more barbaric than inflation, which similarly reduces the real purchasing power of currency.

You have to go into a very quiet place in your mind, away from the noise of the world, the noise of doubters, insecurities and your own self. You have to quiet your disbelief and create open mindedness to your own ability to succeed and overcome.

Stress doesn't come from what's going on in your life. It comes from your thoughts about what's going on in your life.

Governments need to use their money to develop the future, not recover the past. We have to take this chance, if we don't, we're really going to be in trouble.

When considering the prevalence of this disease, we're speaking of 7 million diagnosed patients in the US. But how many Americans currently have the initial stages of Alzheimer's already festering in their brains? I concur with the higher estimates, suggesting around 40 million people.

As I progressed in my career, there were always moments where I asked myself whether I was good enough for that next challenge. I was often the youngest person in the room, and typically the only brown face in the room. I took the fact that I felt I wasn't good enough as a challenge.

Fusion – or 'identity fusion' to be more precise – is basically a form of group alignment in which essential features of your personal identity are felt to be shared with the group. What this means is that there are basically two ways of becoming fused. One is to undergo an experience that becomes a core feature of who you are – such as a painful or frightening ordeal.

Freedom without struggle is an illusion. I love problems. How we deal with problems defines who we are and what values we stand for.

Early customers are animated by belief, not utility. They buy for aesthetic reasons, not practical ones. There's an aesthetically superior future they co-create with the founders. You only want to talk to people who are primed to move to that different future with you.

We try to make decisions through a kind of committee-based approach around what species we're going to bring back, where we're going to invest our dollars, and what fits our core ethos. If it's not going to be beneficial to humans, if we can't do it at arm's length from humans, and if we can't do it in a way that's good for animals, then we just don't touch it.

Even in those very difficult moments, I had enough freedom to choose who I wanted to be in the face of that circumstance. For all of us, the challenge is to rise above our experiences and make choices to choose light over darkness.
