“A burning itch to know is higher than a solemn vow to pursue truth. To feel the burning itch of curiosity requires both that you be ignorant, and that you desire to relinquish your ignorance.”

“A scientist worthy of a lab coat should be able to make original discoveries while wearing a clown suit, or give a lecture in a high squeaky voice from inhaling helium. It is written nowhere in the math of probability theory that one may have no fun.”

“An anthropologist will not excitedly report of a newly discovered tribe: 'They eat food! They breathe air! They use tools! They tell each other stories!' We humans forget how alike we are, living in a world that only reminds us of our differences.”

“Anything that could give rise to smarter-than-human intelligence - in the form of Artificial Intelligence, brain-computer interfaces, or neuroscience-based human intelligence enhancement - wins hands down beyond contest as doing the most to change the world. Nothing else is even in the same league.”

“By far, the greatest danger of Artificial Intelligence is that people conclude too early that they understand it.”

“Do not flinch from experiences that might destroy your beliefs. The thought you cannot think controls you more than thoughts you speak aloud. Submit yourself to ordeals and test yourself in fire. Relinquish the emotion which rests upon a mistaken belief, and seek to feel fully that emotion which fits the facts.”

“I am a full-time Research Fellow at the Machine Intelligence Research Institute, a small 501(c)(3) public charity supported primarily by individual donations.”

“I wouldn't be surprised if tomorrow was the Final Dawn, the last sunrise before the Earth and Sun are reshaped into computing elements.”

“If our extinction proceeds slowly enough to allow a moment of horrified realization, the doers of the deed will likely be quite taken aback on realizing that they have actually destroyed the world. Therefore I suggest that if the Earth is destroyed, it will probably be by mistake.”

“Intelligence is the source of technology. If we can use technology to improve intelligence, that closes the loop and potentially creates a positive feedback cycle.”

“Let the winds of evidence blow you about as though you are a leaf, with no direction of your own. Beware lest you fight a rearguard retreat against the evidence, grudgingly conceding each foot of ground only when forced, feeling cheated. Surrender to the truth as quickly as you can.”

“My parents were early adopters, and I've been online since a rather young age. You should regard anything from 2001 or earlier as having been written by a different person who also happens to be named 'Eliezer Yudkowsky.' I do not share his opinions.”

“My successes already accomplished have mostly been taking existing science and getting people to apply it in their everyday lives.”

“Nothing you'll read as breaking news will ever hold a candle to the sheer beauty of settled science. Textbook science has carefully phrased explanations for new students, math derived step by step, plenty of experiments as illustration, and test problems.”

“Since the rise of Homo sapiens, human beings have been the smartest minds around. But very shortly - on a historical scale, that is - we can expect technology to break the upper bound on intelligence that has held for the last few tens of thousands of years.”

“Textbook science is beautiful! Textbook science is comprehensible, unlike mere fascinating words that can never be truly beautiful. Elementary science textbooks describe simple theories, and simplicity is the core of scientific beauty. Fascinating words have no power, nor yet any meaning, without the math.”

“The media thinks that only the cutting edge of science, the very latest controversies, are worth reporting on. How often do you see headlines like 'General Relativity still governing planetary orbits' or 'Phlogiston theory remains false'? By the time anything is solid science, it is no longer a breaking headline.”

“The obvious choice isn't always the best choice, but sometimes, by golly, it is. I don't stop looking as soon I find an obvious answer, but if I go on looking, and the obvious-seeming answer still seems obvious, I don't feel guilty about keeping it.”

“The purest case of an intelligence explosion would be an Artificial Intelligence rewriting its own source code. The key idea is that if you can improve intelligence even a little, the process accelerates. It's a tipping point. Like trying to balance a pen on one end - as soon as it tilts even a little, it quickly falls the rest of the way.”

“The systematic experimental study of reproducible errors of human reasoning, and what these errors reveal about underlying mental processes, is known as the heuristics and biases program in cognitive psychology. This program has made discoveries highly relevant to assessors of global catastrophic risks.”

“There's a popular concept of 'intelligence' as book smarts, like calculus or chess, as opposed to, say, social skills. So people say that 'it takes more than intelligence to succeed in human society.' But social skills reside in the brain, not the kidneys.”

“Though I have friends aplenty in academia, I don't operate within the academic system myself.”

“To be clever in argument is not rationality but rationalization.”

“We tend to see individual differences instead of human universals. Thus, when someone says the word 'intelligence,' we think of Einstein instead of humans.”

“When something is universal enough in our everyday lives, we take it for granted to the point of forgetting it exists.”

“You cannot 'rationalize' what is not rational to begin with - as if lying were called 'truthization.' There is no way to obtain more truth for a proposition by bribery, flattery, or the most passionate argument - you can make more people believe the proposition, but you cannot make it more true.”
