JUST RECORDED: Elon Just Announced Something Way Bigger Than Tesla

Kind: captions Language: en We're going to profoundly important announcement to make which is the most epic chip building exercise in history by far. This is really going to take things to the next level. So, yeah, a level probably people aren't even contemplating right now. This is not in the I'd call this an sort of an out of context problem. It's not in their context. So, we're going to adjust the context by a few orders of magnitude here. Let's see. It's a joint effort. I'm pressing the button. But the button's not working. Oh, there we go. Okay. But yeah, we aspire to be a galactic galactic civilization. So, I think the future that everyone or most people I think would agree is the most exciting is one where we are out there among the stars. Where we are not forever confined to one planet. That we become a multi-planet species. Like the best science fiction that you've ever read. Or Star Trek or Ian Banks or Asimov or Heinlein. And we want to make that real. Yeah, not just fiction. Turn science fiction to science fact. That's the glorious exciting future that that I certainly look forward to. And it's worth considering like how would you rate civilizations? You know, there's So, there was a physicist, I think he was Russian, in the '60s, Kardashev. He thought about at a high level how would you consider any given civilization? And he said, "If you're type one, you're using uh most of the energy of your planet." And we actually still have quite a ways to go to be properly a type one. We're still using a tiny fraction of the sun's energy that reaches our planet. Let's see. Yeah, there we go. But the Earth only receives about half a billionth of the sun's energy. So, the sun is truly enormous. The sun is 99.8% of all mass in the solar system. So, sometimes people will ask me like, "What about you know, other power sources of power on Earth? What about fusion on Earth?" That is unfortunately very small uh because the sun is 99.8% of mass in the solar system. And Jupiter is about 0.1% and Earth is in the miscellaneous category. We are I think it's Carl Sagan, I think might have said, "Earth is a is like a tiny dust mote in a vast darkness." Very very small. The sun is enormous. So, the way to actually scale civilization is to scale power in space. This is necessarily true uh because that we we actually capture such a tiny amount of the sun's energy on Earth because we're just this tiny dust mote. The Another way to think of it is roughly like electricity production on Earth of all of civilization is only about a trillionth of the sun's energy. Which means if you increase civilization power output by a million, you would still only be a millionth of the sun's energy. It's awe-inspiring to consider that. Just how tiny we are in the grand scheme of things. And we often get caught up in the sort of these sort of squabbles on Earth that are really very minor things in the when you consider the grandness of the universe. And so, I think it's it is important actually to consider the grandness of the universe and what we can do that is much greater than what we've done before as opposed to worry about sort of small squabbles on Earth type of thing. Not much point in that. Yeah, we want to be a civilization that expands to the galaxy with spaceships that anyone can go anywhere they want at any time. That would be epic. And have a city on the moons, cities on Mars, hopefully the solar system, and send spaceships to other star systems. That sounds like the best possible future. So, to do that, we need to harness the power of the sun. And so, a ter fab, while it is enormous, a terawatt of compute per year is enormous by our sort of civilizational standards, it is still just one step along the way of being even a Kardashev. You're still have a long way to go to even be a Kardashev two levels civilization and you're not even registering as a Kardashev three. So, it's a very big thing by current human standards, but still small in the grand scheme. And it's but it's very difficult for humans. So, to to accomplish this very difficult goal really requires a combination of efforts of SpaceX, xAI, and Tesla working together to create this epic uh ter fab project. And uh Tesla and xAI and SpaceX have all done amazing things uh that people did not think would be done before. So, there's a giga giga Texas fab here. Uh there's the Optimus robot that's being built. There's a global supercharging network. It's really quite a lot. And it wasn't that long ago when people thought electric cars wouldn't amount to anything. And there were basically no electric cars for sale when when Tesla started. And people said it was impossible and now Tesla's making 2 million electric cars a year. Yeah. And then xAI, although it's a new company, now part of SpaceX, has also built the first gigawatt scale computer cluster which in record time. Jensen Huang at Nvidia said he'd never seen anything built so fast in his life before. A great compliment for Nvidia. And then SpaceX, I guess you can read it for yourself or you already know. In the reusable rockets, uh people said that reusable rockets weren't possible and even if you did do them, they wouldn't be economically feasible. So, we did them and then we made them economically feasible. And now we've landed over 500 times. And that then we did the the Falcon Heavy and now we're doing Starship. And Starship is a critical piece of the puzzle because in order to scale compute and scale power, you have to go to space, which means that you need massive payload to space. And Starship will enable that. So, this gives you just a sense of scale. We've got Optimus there. Optimus for scale. And Optimus is about 5'11", so it gives you a sense of the size of the Starship V3 rocket. The Starship V4 will be much longer actually. The Starship V4 will make Starship V3 look like short. So, we'll expand with Starship V3 to 200 tons of payload to orbit from 100 tons with start with V3. And then you can see that just the that's just a rough approximation of the AI the mini version of the AI sat. So, that's roughly 100 kilowatts. Uh it's showing the solar panels and the radiator to scale. For some reason there's been a bizarre debate about radiators in space. It's safe to say SpaceX knows how to do heat rejection in space with 10,000 satellites in orbit. Might know a thing or two. So, you can see the radiator is actually quite small relative to the solar panels. And we call that the mini sat since that's uh just 100 kilowatts, we expect future satellites to probably go to the megawatt range. No. So, in order to get to the terawatt of compute per year, uh you need about 10 million tons to orbit per year and at 100 kilowatts per ton. We're confident this is feasible. Like no new physics or impossible things are required to to get there. So, I'm confident actually that SpaceX will get to uh 10 million tons to orbit per year. And then we're building up to a terawatt of solar. So, that solves the we'll we'll solve the solar problem, the power generation. So, then the the key missing ingredient is therefore a terawatt of compute. So, this announcement is about solving the key missing ingredient. To give you a sense of what we're talking about, the current output of AI compute is roughly 20 gigawatts per year. This chart explains why we need to build the ter fab. Because all of the rest of the output from Earth is about 2% of what we need. So, if you add up all the fabs on Earth combined, they're only about 2% of what we need for the terawatt project or ter fab project. We we certainly want our existing supply chain, to be clear, we're very grateful to our existing supply chain, uh to Samsung, TSMC, Micron, and and others. And we would like them to expand as quickly as they can. And we will buy all of their chips. I I have said these exact words to them. And there's a maximum rate at which they're comfortable expanding, but that rate is much less than we would like. And so, we either build the ter fab or we don't have the chips. And uh we need the chips, so we're going to build a terawatt. And we're starting off with an advanced technology fab here in Austin. And I I believe that Governor Abbott is in the audience. I'd like to thank Governor Abbott and the state of Texas for their support. So, in the advanced technology fab, we will have all of the equipment necessary to make a chip of any kind, logical memory, and we will also have all of the equipment necessary to make the uh lithography masks. masks. So, in a single building, we can create a lithography mask, make the chip, test the chip, make another mask, and have an incredibly fast recursive loop for improving the chip design. Uh to the best of my knowledge, this doesn't exist anywhere in the world. Where you've got everything necessary to build logic, memory, and do packaging, and test it, and then do the masks, improve the masks, and just keep looping it. We're not just going to do conventional computing in this. I think there's some very interesting uh new physics that is potentially that that actually I'm confident will work. It's just a question of when. So, this is going to really going to push the limit of physics in compute, and we're going to try a bunch of wild and crazy things, which you can do if you've got that fast iteration loop. That I can't emphasize enough the importance of being able to make a chip, test it, and then make and then change the design, do another one, and have that in a single building. The I I think that our recursive improvement with that situation is probably an order of magnitude better than anything else in the world. Yeah. So, broadly speaking, we expect to make uh two two kinds of chips. The one will be optimized for edge and inference. So, that will be used primarily in Optimus and in the cars, but especially in Optimus because I expect the robots uh humanoid robots to be made 10 to 100 times more than the volume of cars. Vehicle production on Earth is about 100 million vehicles a year, and I expect humanoid robot production to be somewhere between a billion and 10 billion units a year. So, that's a lot. So, yeah, Tesla's going to make a very significant percentage of those is our goal. And then, we need a high-power chip that is designed for space, that takes into account the more difficult environment in space, where you've got high-power you have you have high-energy ions, photons, you got electron build-up. It's a hostile environment in space. So, you want to design the chip, you want to optimize it for space. And and you also want to generally run it a little hotter than you would normally run a chip on Earth to minimize the radiator mass. So, there's just a bunch of constraints that would you design something differently in space uh than you would on on the ground. And for the space compute, my guess is that is the vast majority of the compute because you you're power constrained on Earth. That's why I think it's probably 100 to 200 gigawatts a year of terrestrial chips, and probably on the order of a terawatt of chips in space. Just because of power constraints on the ground is is probably that's probably how it ends up. Space has this advantage that it's always sunny, which is very nice. I I actually think that the cost of AI and deploying AI in space will drop below the cost of terrestrial AI much sooner than most people expect. I think it may be only two or three years before it is actually lower cost to send AI chips to space than it is on the ground. Because in in space, you don't need much in the way of batteries because of it's always sunny. And the solar power you get you're going to get at least five or more times the solar power you get in space versus the ground because you don't have atmospheric attenuation or a day-night cycle or seasonality. And you're always uh normal to the sun. So, you're really maximizing the the solar power at that point. And this is the uh space solar actually costs less than terrestrial solar because you don't need heavy glass or framing to protect it from extreme weather events. So, as soon as the cost to orbit drops to a low number, it immediately makes extremely compelling sense to put AI in space. It becomes a no-brainer, basically. Moreover, as you go to to space, you get increased economies of scale, and things get easier over time, whereas as you try to put more and more power on the ground, you run out of space, and you start using up the easy spots, and then you get next-level NIMBY. Uh nobody wants the thing in their backyard. So, then so actually increasing power on Earth has becomes harder over time, and more expensive over time, but in space, it becomes actually cheaper and easier over time. These are very important points. Yeah. >> [music] >> What you just saw there was because of course you're asking, what's on your mind is, well, what do you do after a terawatt? Don't think small. Well, yeah, good point. Uh so, we know how do you get to a petawatt? Is the obvious next question. And you get there by having an electromagnetic mass driver on the moon with robots with Optimus, and obviously lots of humans. And with that, you can send a petawatt. You can create a petawatt of compute and send that to uh deep space because on the moon, moon has no atmosphere and has 1/6 Earth gravity. So, you can you don't need rockets on the moon. You can literally accelerate it to escape velocity from the surface. And that dramatically drops the cost once again of harnessing power, and and enables you to go 1,000 times bigger than a terawatt. So, for sure the future I want to see I want to just live long enough to see the mass driver on the moon because that's going to be incredibly epic. Yeah. That should hopefully get us to a millionth of the sun's energy, at least. Humbling to think about that. But a millionth of the sun's energy would be a million times bigger than Earth's economy, so it's good from that perspective. And then, yeah, you expand beyond that to the planets, to the other stars, and create the most exciting possible future that that I can imagine. This looks a bit like the opening in Idiocracy with the Mike Judge. Unlocking an age of amazing abundance. Yeah, obviously elements of that are sustainable energy, space travel, and AI and AI and robotics that bring amazing abundance to everyone. And it's really the it's really the only path to amazing abundance is AI and robotics, which is not to say it can't go wrong. Uh hopefully, but I think it'll probably go right, and it'll be a future that you love. And it's the best future I can think of, at least. And then, we go beyond the moon, beyond Mars, and we sail through the rings of Saturn. Now, wouldn't it be amazing if you could buy a trip to Saturn? Or frankly, if you just have a trip to Saturn. I think things will just be free in the future. It sounds nuts. You know, if you've got an AI or robotics economy that is anywhere close to a million times the size of the current Earth economy, literally any need you possibly want can be met. If you can think of it, you can have it. So, I think Iain Banks in his Culture books has it pretty much right, where there there actually isn't money in the future, and there is abundance for everyone. If you can think of it, you can have it. That's it. Which means anyone could have a trip to Saturn. It won't be, you know, just a few people. If you want it, you can have it. Yeah. So, >> [applause] >> yeah, join us on this journey, and help us design incredible chips, and make incredible chips, and build a terawatt of chips, a terawatt of solar, and 10 million tons to orbit per year. Thank you. >> [music]
