When you tell people these things, they get a little fatalistic about it. They tend to think, 'Well, I guess there's not much I can do about that.' I would call that a bias. It is wrong just as often as it's likely to be right. We really need to interrogate and deconstruct that assumption. It's rarely true, and it can lead people to internalise some of these effects in a way that can be pretty damaging and totally unnecessary.

Everyone has a little bit of warrior in them. We all grow up and have a little piece of us which wants to be a superhero, who goes and fights the bad guys. In real life, fighting is tough, you have to overcome your fears – nobody really wants to get into a fight! Escaping that fear is the reason so many people who get into combat sports.

Super intelligence would be the last invention biological man would ever need to make, since, by definition, it would be much better at inventing than we are. All sorts of theoretically possible technologies could be developed quickly by super intelligence — advanced molecular manufacturing, medical nanotechnology, human enhancement technologies, uploading, weapons of all kinds.

I realized that while others may not always do things precisely as I would, they might accomplish 80% or 90% of it, and that was acceptable. A defining moment came when I relinquished control over the marketing brochures, my annual pet project.

History is not linear, like the chapters of a book… History moves through seasons, and so winters are inevitable.

You feel like a product when you're on these things. You feel like you're selling yourself. But what's amazing is that when you get people in person, actually interacting, much of the time they don't do that same optimisation, especially if you give them just a few nudges.

There's just enough in your control where you think you should be able to perform or deliver on any given day – but when you really sit and think about it, you're basically trying to be predictive text for the ocean.

You can't control what happens to you, you can only control how you react to it. So, focusing on what's in your control and accepting for the time being what's beyond your control is a really useful therapeutic idea.

I remember at Netflix, after we went public, the parking lot changed from old Volvos and station wagons to Mercedes' and BMW's. That really made me happy; not the cars per-say, but the fact that all those families could now send their kids to school and college.
