Here's what I'm now realizing... Putting energy generation in space (via orbital solar arrays) doesn’t just solve the power bottleneck for 100 TW of orbital data centers. It likely triggers a cascade that will relocate entire categories of energy-hungry activity off-Earth. I wonder what other energy intensive industries will greatly benefit from moving to space? @aaronburnett - has your team thought about this?

SpaceX Musk compensation incentive goal: 100 TW "operates data centers in space that provide at least 100 terawatts of compute capacity." Remember the famous Terafab chart showing 1 TW labeled "Expected compute demand from Tesla + SpaceX"? The Musk milestone is 100 TW. Have they gone insane? Actually no. We could hit 100 TW of demand in less than 10 years. Today global AI data center power capacity is about 30 GW. Let's check this against growth in the CPU growth era, 1980-2000's. The growth rate then was 58% per year (growing at 1.58x per year). By that measure, 30 GW will grow to 1 TW in 7.7 years (2034). And 100 TW at 17.7 years (2043). BUT, AI compute demand is growing much faster than the CPU-era growth. About ~3.4× per year. That’s more than twice as fast as the historical 58% rate. So the demand for 1 TW equates to only 3 years and 100 TW only 7 years. Even in the most optimistic case (e.g., 1.5× FLOPS/W efficiency gains every year from Blackwell/Rubin-class chips), we still hit 1 TW in ~4.3 years and 100 TW in ~10 years. And I think inference compute demand is going to accelerate from here!

@elonmusk Full Self-Driving Supervised! That’s like saying I'm driving alone, but my mom is sitting right next to me. If we still need hands on the wheel after 10 billion miles, why not just call it a taxi.

@SawyerMerritt 10Bn FSD miles only took 30 days, when estimated at 41 after 9Bn. How about sponsoring a contest to guess the date/hour/minute for 11Bn?

@Object_Zero_ @chamath @gustaf Condescend much? I read @chamath question to mean could a new material, which is sooo much more efficient for solar panels be discovered/invented that the 500:1 panel:data footprint implodes to 50:1 or less, changing the future of energy for everyone.

Chamath our energy problem is mechanical work, not compute. We have Moore’s law for compute, we don’t have anything like Moore’s Law for mechanical work. Carrying grocery bags requires a certain amount of energy, and no new material science of better chips ever changes that. The data center demand is transitory, the autonomous machine demand is the real crunch ahead and it’s 20-50x what we face today.

This 100MW data center in UAE is the largest solar powered datacenter in the world. There are currently 1,300 data centers in the world that are bigger than this one, but this one is the largest solar powered one. That’s 10 square kilometres of solar panels you can see. The datacenter itself is 0.02 square kilometres, so a solar powered datacenter is ~500x larger than a data center using any other form of power. A five hundred times larger site. UAE has some of the highest solar irradiance anywhere on Earth, it is an inhospitable desert. Averaging 9.7 hours of sunlight per day with average irradiance above 2,200 kWh/m^2. If you build this somewhere else, you need more solar panels because your irradiance will almost certainly be lower. Even if the world had an infinite supply of free solar panels, solar power will not be free. Anyone who has ever done major capital projects, who looks at where data centers need to be in the next 5 years and the next 10 years… we know it aint solar. Sorry. You struggle to even build a train track that’s 100 miles long and 10ft wide anywhere in the West, there is zero chance of build 100 square mile solar farms for GW compute. This is why people are talking about space compute. Deploying into space is one strategy to solve the constraints. But there are faster and more scalable strategies, that get you to mass deployment of multi GW data centers. There are strategies that also allow you to power the 10 billion robots and their newtonian actuators, that immediately follow the inference demand cycle. Step back and look at the full cycle of this industrial revolution… There will be billions of chips, but there will be trillions of actuators. This biggest part of this revolution is the embodiment cycle, and it’s big by a factor of 20 or 50x over the stuff that comes before it. There is no analogy in human history for the scale of this economy, of the demand it will place on energy and commodities. The humans own the Earth, and if you exist inside their legal system, they won’t let you turn the surface of their planet into glass. But they do want your chips and your actuators to serve their needs and desires. There is a way to do all of this, and so it will happen.

@thejefflutz @PeterDiamandis This is an uncharacteristically ridiculous post from Peter. In literally no universe will they be making 576 robots a day in four months from now. Although I do have to admit if this were an Optimus story my take would probably be different.

@PeterDiamandis Sorry but this is not a valid method of quantifying preproduction scale … this is like someone being asked about their height and responding they’re at 5x improvement over their height as a baby. There are so many other factors to consider

Figure Robot Production is SCALING... They just went from building 1 Robot/day to 24 Robots/day. Manufacturing scaled 24x in 120 days. The humanoid production curve looks exactly like the early days of Model T assembly lines... and soon will scale to iPhone rates.

Treasury Secretary Scott Bessent@SecScottBessent

It is unusual for soon-to-be-former Fed Chair Jay Powell to stay on at the @federalreserve. For someone who speaks so often of norms, his unilateral decision to stay flies in the face of tradition. Kevin Warsh will bring about a new day at the Fed, with accountability, management, and sound policymaking in the lead.

Halter announced today the launch of direct-to-satellite connectivity using SpaceX's @Starlink for its smart cattle collars, a world-first that removes the need for cell towers or on-ranch infrastructure. "Using Starlink enables ranchers to manage cattle anywhere they can see the sky. Combined with a suite of new tools for reproduction, animal behavior, and precision pasture management, the release significantly expands what is possible for cattle ranch management. Beef ranchers in remote and rugged regions that were limited by connectivity can now turn to virtual fencing to run more productive and sustainable operations - at a time when they face rising fuel costs, labor shortages, and an aging workforce pressures." Halter’s internal modeling estimates direct-to-satellite capability expands coverage of the U.S beef cattle market by 2.5x. Until now, Halter’s solar-powered, GPS-enabled collars relied on Halter’s proprietary long-range radio towers. With direct-to-satellite, the collars can communicate via Starlink, eliminating ground infrastructure entirely.

Whoah, self-driving cars compete with airlines. I never considered that till now.
Nahuel Hilal - TattooGuy@nahuelhilal

Yesterday I drove my @tesla 900 miles on FSD from Miami to Nashville and I realized it’s genuinely the better option. I fly that route 2 to 3 times a month. Flights are never under $400. Most times $600. Sometimes $800. Add Uber to and from both airports, or parking garage fees. Then factor in the delays, the cancellations, the security theater, the chaos, the guy next to you who hasn’t met deodorant yet. On the other hand: I pack healthy snacks, press one button, and the car just goes. I took calls. Replied to emails. FaceTimed my family. Ate without pulling over. Did everything I normally do on a travel day, except none of the stuff that makes travel days miserable. My biggest concern going in was range and charging. Here’s what actually happened: My bladder needed one extra stop the car didn’t even suggest. Most charging stops were under five minutes. Total cost for the whole trip was less than just the uber to the airport. And this was the base model Y. Now I’m thinking I should get something comfier and just make this the default.
