But it can be liberating to see how thoughts pull the levers of emotion — and how negative emotions in turn set the stage for patterns of thinking th… - Sam Harris

Tegmark: That’s right, and there’s a more elemental example. In a certain sense, your genes have invented you. They built your brain so that you could make copies of your genes. That’s why you like to eat — so you won’t starve to death. And that’s why we fall in love — to make copies of our genes, right? But even though we know this, we still choose to use birth control, which is the opposite of what our genes want.
Some people dismiss the idea that there will ever be anything smarter than humans for mystical reasons — because they think there’s something more than quarks and electrons and information processing going on in us. But if you take the scientific approach, that you really are your quarks, then there’s clearly no physical law of physics that precludes anything more intelligent than a human. We were constrained by how many quarks you could fit into a skull, and things like that — constraints that computers don’t have. It becomes instead more a question of time. And, as you said, there’s a relentless pressure to make smarter things, because it’s profitable and interesting and useful. The question isn’t if this will happen, but when. And finally, to come back to those ants. Suppose you’re in charge of a huge green-energy project, and just as you’re about to let the water flood the hydroelectric dam you’ve built, someone points out that there’s an anthill right in the middle of the flood zone. Now, you know the ants don’t want to be drowned, right? So you have to make a decision. What are you going to do?
Harris: Well, in that case, too bad for the ants.
Tegmark: Exactly. So we ought to plan ahead. We don’t want to end up like the ants.

The paradox is that we can become wiser and more compassionate and live more fulfilling lives by refusing to be who we have tended to be in the past. But we must also relax, accepting things as they are in the present, as we strive to change ourselves.

The men and women on death row have some combination of bad genes, bad parents, bad ideas, and bad luck — which of these quantities, exactly, were they responsible for? No human being stands as author to his own genes or his upbringing, and yet we have every reason to believe that these factors determine his character throughout life.
