"This is crunch time for the whole human species, and not just for us but for the intergalactic civilization whose existence depends on us. This is the hour before the final exam and we're trying to get as much studying done as possible. It may be that you can't make yourself feel that for a decade or thirty years or however long this crunch time lasts, but the reality is one thing and the emotions are another... If you confront it full on, then you can't really justify trading off any part of intergalactic civilization for any intrinsic thing you could get nowadays, and at the same time, it's also true that there are very few people who can live like that ."

“My experience is that journalists report on the nearest-cliche algorithm, which is extremely uninformative because there aren’t many cliches, the truth is often quite distant from any cliche, and the only thing you can infer about the actual event was that this was the closest cliche.... It is simply not possible to appreciate the sheer awfulness of mainstream media reporting until someone has actually reported on you. It is so much worse than you think.”

“Rationality is the master lifehack which distinguishes which other lifehacks to use.”

“If people got hit on the head by a baseball bat every week, pretty soon they would invent reasons why getting hit on the head with a baseball bat was a good thing.”

“There are no surprising facts, only models that are surprised by facts; and if a model is surprised by the facts, it is no credit to that model.”

“You turned into a cat! A SMALL cat! You violated Conservation of Energy! That's not just an arbitrary rule, it's implied by the form of the quantum Hamiltonian! Rejecting it destroys unitarity and then you get FTL signalling! And cats are COMPLICATED! A human mind can't just visualise a whole cat's anatomy and, and all the cat biochemistry, and what about the neurology? How can you go on thinking using a cat-sized brain?”

“In the universe where everything works the way it common-sensically ought to, everything about the study of Artificial General Intelligence is driven by the one overwhelming fact of the indescribably huge effects: initial conditions and unfolding patterns whose consequences will resound for as long as causal chains continue out of Earth, until all the stars and galaxies in the night sky have burned down to cold iron, and maybe long afterward, or forever into infinity if the true laws of physics should happen to permit that. To deliberately thrust your mortal brain onto that stage, as it plays out on ancient Earth the first root of life, is an act so far beyond "audacity" as to set the word on fire, an act which can only be excused by the terrifying knowledge that the empty skies offer no higher authority.”
