Maybe you can't copyright infringe in space, but it's still infringement when the result gets back to earth.
Keep the result in space, and use large telescopes to look at it!
Very confused by this plan. Data centers on Earth are struggling with how to get rid of waste heat. It's really, really hard to get rid of waste heat in space. That seems to be about the worst possible place to put a data center.
You are confusing engineering challenges with show stoppers. Cooling in space is a well studied problem with a few possible solutions. They all boil down to needing a lot of mass to radiate heat out to the universe and ways to conduct heat. We've been doing that at small scale for decades. SpaceX is already operating a fleet of many thousands of satellites that they built and engineered. They'd be well familiar with…
Who is going to pay the money to rent capacity in space when they could rent the same capacity on Earth for a fraction of the cost?
The really crazy thing is you don't need to know more then basic (non Hollywood) physics to know how dump this is 1. every gram you need to send to space is costly, a issue you don't have at ground level 2. cooling is a catastrophe, sure space is cold, but also a vacuum, so the cooling rate is roughly the infrared radiation rate. This means if you are not careful with the surface of a satellite it can end up being ve…
I don't know if data centers in space make sense or not, but I'm really not liking these comments that say something is "too expensive" or "too hard" without actually crunching the numbers to verify if it actually is. It's like you point out a number of completely obvious problems with the scheme and immediately, without any detailed analysis or expertise (I know this, because surely you can't have expertise in all o…
Sure, until you need to replace or upgrade it. How long does a server on earth last for, how often does it need maintenance / replacing? And how long is the expected or desired lifetime for a server in space? Then calculate weight and cost etc.
> Maybe the running costs are cheap enough to offset this.
"Maybe" is hope, you can't build a business on hope / wishful thinking. And the running costs for data centers on earth can be reduced too if you build them the same way as a sattelite - solar panels + battery + radiative cooling gives you enough data to compare. But servers / data centers aren't built that way because of cost vs benefit.
> If achieving the cooling is only very hard and requires careful material engineering, then it can be worked out and they will get it done.
See, it's possible for sure - we HAVE computers in space, powered, cooled, running 24/7. The questions are whether it makes economic sense, both launch costs and running / maintenance costs. That's straight math, and the math isn't mathing.
> I suppose they could make something like the International Space Station, which would get regular traffic back-and-forth exchanging and servicing hardware as needed.
Sure, but the ISS itself cost ~100 billion to build and operate - probably more, this is based on a ten second search query. While I'm sure launches are cheaper than ever and will be even cheaper in the future, it's still tens of billions to build a data center in space, plus you'd need astronauts, supplies, hardware, etc - all a LOT more expensive than the equivalent processing power on earth.
> These are collective problems for the whole of humanity and will not concern an individual actor such as Elon Musk who wants to send more satellites into space.
True, so we as humanity should offer resistance to plans to launch thousands of objects into space unless they have a clear and definite benefit. I'm not worried about Starlink, it's a benefit to all the areas that don't have (open) access to the internet and they're in low-earth orbit so they'll fall back within 5 years. But I just don't see the benefit in putting datacenters in space, not when it's so much cheaper and more viable to put them on earth.
I'm convinced that >30% of this comes from ideas leaking out of fiction such as like Neuromancer , and percolating through the minds of wealthy people attracted to some of the concepts. Namely, the dream of being a hyper-wealthy dynasty, above any earthly government, controlling an extraterritorial Las Vegas Fiefdom In Space. (Which in the book, also hosted a powerful AI.) Then they work backwards, trying to figure o…
This idea came from musk wanting to fold his X and xAI investments in with his (likely successful) spaceX IPO.

The French government issued a child porn warrant for the CEO and it isn't even a topic for discussion. That's what doesn't make sense to me. It's silly to talk about solar panel prices like reality matters at all to his cult of followers. It doesn't have to make sense. The less sense the better.

I’ve come to think of interviews with people like Sam Altman as “freestyle science fiction.” They’re just saying stuff off the top of their head. Like you say, that often entails vague ideas from other sci fi percolating up and out, with no consideration of if they actually make sense. And like most freestyle, it’s usually pretty bad.

Simply put no, 50MW is not the typical hyperscaler cloud size. It's not even the typical single datacenter size. A single AI rack consumes 60kW, and there is apparently a single DC that alone consumes 650MW. When Microsoft puts in a DC, the machines are done in units of a "stamp", ie a couple racks together. These aren't scaled by dollar or sqft, but by the MW. And on top of that... That's a bunch of satellites not e…
How much of that power is radiated as the radio waves it sends?
Earlier quoted context omitted.
It sounds hard but it shouldn't not make sense. 1. Solving cost of launching mass has been the entire premise of SpaceX since day one and they have the track record. 2. Ingress/egress aren't at all bottlenecks for inferencing. The bytes you get before you max out a context window are trivial, especially after compression. If you're thinking about latency, chat latencies are already quite high and there's going to be…
> There is probably plenty of scope to optimize space radiators. It was never a priority until now and is "just" an engineering problem. Well, it's a physics problem. The engineering solution is possibly not cost efficient. I'd put a lot of money that it isn't.

The story here is even simpler. SpaceX is going public this year. Elon made a monumentally shitty investment in Twitter and then poured a stupid amount of money into xAI at the peak of the cycle. By having SpaceX buy xAI, he gets to swap worthless shares in that company for more SpaceX liquidity. Simple as that.
Exactly, and there needs to be some economic justification for a giant rocket. There is no money to be made by going to Mars, and AI data centers in space could attract investors (who are just riding the data center hype).
I find this to be the most obvious game plan here. Makes total sense from financial engineering point of view.
You _might_ get to develop nice tech/IP to enable other space based businesses at the same time. "we sold them on X but delivered Y". So it's a bit of a hail mary, but makes total sense to me if you want to have a large budget for inventing the future.
Once you can demonstrate even a fraction of this capability of operations ... I think you can sell a "space dominance" offering to Pentagon for example and just keep pedaling.
"We are going to build the perfect weapon" does not necessarily entice as large engineer population as "we are going to Star Trek".
Another thing - if Moon is going to be a thing, then _properties on Moon_ are going to be a thing.
In theories of value in post-ai societies scarce assets like land are going to become more valuable. So it's a long term plan that makes sense if you believe Moon will be a realestate market.
I would not assume cooling has been worked out. Space is a vacuum. i.e. The lack-of-a-thing that makes a thermos great at keeping your drink hot. A satellite is, if nothing else, a fantastic thermos. A data center in space would necessarily rely completely on cooling by radiation, unlike a terrestrial data center that can make use of convection and conduction. You can't just pipe heat out into the atmosphere or build…
It could also just be ignorance and talking out of his ass to look smart. Like when he took over Twitter and began publicly spewing wrong technical details as if he knew what he was talking about and being corrected by the people actually working on the product.
