Travis Kalanick on the physical world as an atoms-based computer: "The vision for digitizing the physical world for me started at Uber. Treating atoms like bits started at Uber. It was sci-fi at one point. You would touch glass and a car would come to you." "CPU manipulates bits....

back in 2017 i was interning as an equities analyst at a fund in nyc, which had a 9am morning call every weekday. the purpose of this call was to discuss quarterly earnings or current events or whether we should be buying nvidia (at the time, on a tear because of the '17 crypto boom), but one morning in june the call opened with a bunch of people freaking out because some guy named "travis" had resigned. after a couple of rounds of "travis is gone" "did they fire him" "bloomberg says he resigned," i was especially confused because the firm had a portfolio manager named travis, and i looked over at his desk and he was still sitting there, not being escorted out by security or anything. who was travis? it was only after things had calmed down that i realized the people on this call were talking about *travis kalanick* of uber, a figure who loomed so large in the minds of wall street investors that even *two years before* uber ipo-ed, the news of his departure was treated like a six sigma event. everyone wanted to know: if travis was gone, what would happen to his company? even in his uber days, travis was the bits and atoms guy (watch the video clipped in the first ~2 minutes of the below podcast for proof of that). and in order to be a bits and atoms guy - as in, the kind of guy who's so discontent with the slow, staid, schlerotic state of things that he has to painstakingly reorchestrate the physical world with computers, perhaps pissing off some powerful interests along the way - some people might call you difficult. some people will not understand your vision. some people will try to get you fired. but if you're a bits and atoms guy, you never stop being one. you might retreat into near-obscurity, or spend years wandering in the wilderness, biding your time in exile. but you will not stop building. and one day you will return triumphant like a modern-day charles de gaulle, even better than ever, and ready to prove wrong everyone who didn't understand the first time around. being in a room with travis leaves you pretty pumped up. you can see why he's such a rallying leader, and why (by my count) at least six top uber execs have chosen to follow him to his new company, atoms. it isn't simply that the job isn't finished (although that's a big part of it, as travis attests). it's also because it's clear that there are very few leaders like travis out there: people who have such a holistic worldview that they can get people who would otherwise be founders themselves to join the ride and help build an extremely specific vision for the future. here are some things that stood out to me from this event: -travis is a branding/comms mastermind. he deploys memorable phrases like “food computer,” “wheelbase for robots,” “atoms as bits” and describes his vision for cheap meal delivery as "autonomous burritos." you can see why people get excited for his vision for the future. there's extraordinary complexity in what atoms is trying to do, but travis makes each step along the way feel manageable because he can distill these ideas into extremely concrete images. -atoms is building full-stack autonomation for three different divisions: food, mining, and transportation. food supplies the real estate, software, robotics, and logistics laboratory; mining supplies a commercially deployed autonomy business; and transport is intended to become the reusable movement platform connecting multiple physical industries. travis argues humanoids make sense for diverse, low-volume work in spaces designed for people. but at industrial scale (which atoms is doing), purpose-built machines should win on throughput, space, cost, and reliability. -the best way to get over your last company may be the same as the best way to get over your ex: fall in love again. travis says anger and fear of failure can carry a founder through years of pain, but they also produce long nights where very little gets done and sharp elbows felt by everyone around you. atoms is what happened when he learned to build toward a future rather than against an enemy. -doing hard things is a reminder you can do more hard things. in the q&a ben remembers travis describing attacks by chinese ride-sharing companies as proof that, if he could survive china, the rest of the world would be manageable. travis still deliberately creates problems when things become easy. but the rate of problem creation cannot exceed the organization’s rate of problem-solving. such a fun talk and q+a with travis kalanick benahorowitz.eth Erik Torenberg ! check it out.

I am a physicist and I'm profoundly opposed to any idea of non-physical explanations that contradict physics. So that's a no-no and really doesn't make sense. However, there are ways in which both emergent properties such as minds and life and so on have an effect. And as you said, also abstractions. Now the fact that the theory of good explanations led to the idea that abstractions are real things was slightly surprising to me. I wasn't expecting the link, at least wasn't expecting it to be so strong as it is. But the thing is, if you think about how to explain events, physical events like a footprint on the moon, how do you explain how that happened? Well, it happened because of human ideas, of science. And human ideas, you could say in this reductionist sense that as you rightly say is the prevailing mode of explanation and the prevailing idea is to look down on other modes of explanation, that those ideas are nothing more than configurations of atoms. So some physicists, some rocket scientists put their brain into certain configurations of atoms and those atoms then acted on other atoms which then ended up making a footprint on the moon. Now what that misses is the explanation of why certain configurations of atoms put footprints on the moon while others, the overwhelming majority of configurations that human brains, even human brains have been put into in history, do not have that effect. And it's because there's a certain type of information. And this information can't in my view be reduced to statements about atoms because if you think about what that information does, it is in brains but the same information then gets transferred into, let's say, sound waves in air and then it gets transferred into ink on paper and then it gets transferred into magnetic domains inside a computer which then control a machine that instantiates those ideas in bits of steel and silicon and so on and so on. There's an immense chain of instantiations of the same information. And it's only special kinds of information that have this property that they are preserved and instantiated in successive physical modes. So what is being transmitted, what is having the causal effect is not the atoms but the fact that the atoms instantiate certain kinds of information and not other kinds. So therefore it is the information that is having the causal effect. If a particular instantiation of that information were damaged, then processes would come along to fix it, whether or not they could fix the physical instantiation. For example, if the computer goes wrong, then we don't use the corrupted information. We go back and rescue the information from a different computer and we throw away the atoms that at one point instantiated it. So the information causes itself to remain in existence. Now I think there's no way out of that mode of explanation. And if explanation is going to be the fundamental thing about our criterion, for example, about what is or isn't real, then we have to say that information and this particular kind which we call knowledge is real and really does cause things.

Richard Feynman on the one idea that explains almost everything around you: 1. heat isn't a substance. it's motion. when something feels hot, its atoms are jiggling fast. when it's cold, they're jiggling slow. that's all temperature is... speed. 2. when a warm cup heats your hand, nothing actually flows into you. the fast atoms just bump the slow ones and speed them up. heat "spreading" is only jiggling passed along by touch. 3. atoms never lose energy. a bouncing ball slows and stops... but the motion doesn't disappear. it leaked into the floor. the ball goes still, the floor gets a little warmer. the motion is still there. just scrambled. 4. hammer a piece of metal long enough and it gets hot. you added no heat. you just jiggled it harder. pounding is heating. 5. a drop of water pulls into a ball because the atoms want partners on every side. the ones at the surface only have them below. so they keep clawing inward, trying to get in. that's what rounds the drop. 6. that same drop is slowly vanishing. atoms at the surface keep breaking free into the air, one by one, until none are left. you're watching them leave. 7. ice, water, and steam are the same atoms at different speeds. slow, and they lock in place like oranges in a crate... ice. faster, and they roll over each other... water. faster still, and they fly apart... steam. 8. pump up a bike tire and the pump gets hot. squeezing the air speeds the atoms up. let the air expand and it cools, because the atoms hit a piston that gives way and lose speed. heat and cold are hiding in a bicycle pump.

Elon Musk just measured your existence by how many times your atoms have been inside a dying star. Musk: “How many times have your atoms been at the center of a star? I think it’s like on average three or four times.” Every atom in your body has already survived the core of a star. Multiple times. Crushed under pressures that would flatten planets. Superheated to millions of degrees. Blown apart in explosions so violent they forged new elements. Then gravity pulled those scattered pieces back together. New stars formed. And the cycle repeated. For 13.8 billion years, your atoms have been fuel for the most violent process in the universe. And they are not done. Musk: “In terms of existence as measured by the number of times your atoms will be at the center of a star, we seem to be roughly halfway.” Halfway. Your atoms have been through the furnace three or four times. They will go through three or four more. But right now, in this impossibly thin sliver between cycles, those atoms are doing something they have never done before. They are conscious. For billions of years before you, they burned through stellar cores with no awareness. No memory. No sense of what they were or where they had been. After you, they will return to that state. Unconscious matter drifting through space until the next star claims them. This is the only moment in their entire journey where they can look back at the stars that made them and understand. Musk: “If you want to look at the big picture… that’s the really big picture.” The big picture is not that we are small. Everyone already knows that. The big picture is that we are temporary witnesses to a process that does not need witnesses. Stars do not need observers to burn. Atoms do not need anyone to understand where they have been. The universe ran for billions of years with no one in it. It will run for billions more after the last conscious thing disappears. But right now, matter is examining itself. That has never happened before in 13.8 billion years. You are not a person who happens to contain ancient atoms. You are ancient atoms that briefly figured out how to think. The universe did not design consciousness. It designed stars. Consciousness was the accident. And the accident is half over.
