Yeah, right. Why do they only have a handful of these cars in each city, when supposedly wait times are super high for them? Why don't they just put more of these in service, if they're just Teslas? I suspect the answer is because they're being remotely monitored and operated 24/7, and they don't have the staff to tend to them. But only Tesla knows, and they've spent the last few years absolutely destroying their rep…

Well, yes, exactly. They’re doing a cautious roll out. If they didn’t you’d be canning them, and you’re canning them anyway. It feels awfully like you don’t want them trying to roll out new tech at all. Funny take for someone on hacker news to have.

That’s hilarious.

They’re not doing a cautious rollout. Tesla has repeatedly shown nothing but contempt for their customers and their safety. And they lie constantly, about everything.

No, they’re doing a fake rollout. They painted themselves into a corner with their technical approach, and this fake “unsupervised” robotaxi thing is just the latest way to prop up the stock price and stall while they try and figure out how to make this work.

And no, I do NOT want Tesla to roll out “new tech”, since they have proven that they lack the seriousness and engineering rigor to do so safely. Fuck Tesla, and fuck the regulators who let them drive their shitty cars on public roads.

Hope that clears it up for you.

> If we hadn't gone to space at all and focused on Earth first we wouldn't have GPS I'm not sure if you're actually suggesting it or not with this statement, but we didn't need manned space flight to have GPS. We started launching satellite-based navigation systems a little bit before Yuri went to space, though the system wasn't in fully operational service until after a few human spaceflights.

I'm saying if we'd decided that Earth-bound spending was more important and we should dig (and then maintain) wells in Africa instead of ever going to space, we wouldn't have useful things like GPS.

Let me start off by mentioning I'm generally for spending on space science programs and think the US should generally be doing more of it not less.

But I'd once again push back against the idea that GPS wasn't "Earth-bound spending". Its entirely an Earth-bound thing. GPS is useless on the moon, its useless on Mars. It doesn't help space probes go to other plants. It doesn't help our space telescopes. We didn't really learn new things about going to space by building our GNSS (although IIRC we did confirm some concepts related to time dilation). We didn't build new rocket designs to put them in orbit. They weren't the first things we put in space (although they were some of the earliest things). They were not space science systems. GNSS are inherently Earth-focused spending (global being a key word there).

We didn't build Transit or GPS or GLONASS or Galileo to explore space, we did it to measure things on the Earth. GNSS are very much Earth-bound spending, and would have happened regardless of us putting a man on the moon or sending probes to Mars or beyond.

We didn't even originally build the rockets launching a lot of this for science reasons or for looking towards exploring space, we originally built them to blow up people far away from us. The Atlas LV-3B for Mercury was a modified ICBM. The Gemini Launch Vehicle was essentially a modified Titan II, a nuke-capable ICBM. These rockets were being built and launching payloads regardless of if we put people on them and did science with them. IMO its a good thing we also did science with them, but its not like they were originally built for public science like NASA programs.

Ok, this is not a reasoned argument anymore is it?

What do you think isn't reasoned? You came up with an extremely arbitrary choice. I pointed out that if you were in a position to make that choice, you have much better options somewhere in between. Then you talked about the more general idea of moving all industry off the planet, and sure that's nice but this is not the industry you want to start with, it should be one of the last ones you worry about. If someone's…

You're still not getting it. You still have to ask permission from places. That's the point. In orbit, nobody is going to care. And you're using words like "should" - should has no place in this discussion. It's an "is-ought" thing. You're saying "they should behave this way" and I'm saying, "they're going to behave this other way."

You haven't reasoned through any of this, you're saying that they "should" do something because it will be cheaper/better/whatever. And that's not how it works - it was never how it worked, but it was less obvious in prior times.

There aren't really any better options. Your bottlenecks are power, land costs, technical stuff, and bureaucracy. In space you basically shortcut all of those problems except the technical ones, and (and this is unbelievably important too), it brings the costs of other things you're doing on orbit down. Sure you "could" build data centers in Arizona or whatever, but they're not going to because they'd have to ask permission, it'd be a permitting nightmare, etc.

These guys are also thinking about opportunity cost. So, say you can build AGI++ you just need more compute. What is the opportunity cost of building terrestrially if it takes you 4 years to build this with an extra year for legal requirements?

Admittedly it is not my field, but back of the envelope calculations in a sun synchronous orbit with the radiators pointed towards deep space seem pretty plausible with about 1.3 to 1.7 ratio of solar area to radiator area. Like, it's not "great" but if you're not flying around the sun every 72 minutes or whatever and you can keep your panels sun on and radiate into deep space, the numbers aren't bananas.

Is that ratio just for collecting the sun's energy. Or does it include using it?

I sized for an H100, so using it.

You need a cell tower every 20 miles or so, less for a performant one. There's not dark fiber at that density in remote regions (remote is, by definition, lacking infrastructure). There's a better chance of power, and for the cases there's not, solar/battery is fine for a cell tower, especially one designed for lower power remote installations.

The initial cost for a dark fibre on a power pool is very low and can give you low latency and high bandwidth. Starlink antenna needs a lot more energy and has a high montly cost. That shouldn't be very economically for long.

Launches need permission too.

My "should" is a summary of the incentives if they acted reasonably. Without a crystal ball, don't be so confident they'll do something different.

And here's a version with no is or ought: Anyone whose goal is avoiding datacenter downsides, that could say "we forbid polluting and power grid draining datacenters here" but chooses to say "we forbid any datacenters here, go to space", is a moron. And anyone that doesn't have the power to say either is irrelevant.

> You haven't reasoned through any of this, you're saying that they "should" do something because it will be cheaper/better/whatever. And that's not how it works - it was never how it worked, but it was less obvious in prior times.

Companies almost always do what's cheaper. Your logic is incomprehensible here.

> There aren't really any better options. Your bottlenecks are power, land costs, technical stuff, and bureaucracy. In space you basically shortcut all of those problems except the technical ones

If the satellites self-powering counts as not buying electricity, then so does self-powering on land. Land in the middle of nowhere is very cheap, and so is the bureaucracy per acre when you're buying large chunks. It's less bureaucracy than rocket launches. And the technical stuff is a lot simpler on land than in space; suggesting you avoid technical stuff by using rockets is crazy.

> Sure you "could" build data centers in Arizona or whatever, but they're not going to because they'd have to ask permission, it'd be a permitting nightmare, etc.

A baseless claim.

When you're happy with the middle of nowhere, building on land only requires a handful of approved sites on the entire planet. That's very achievable, and achievable faster than it takes to set up the production lines.

>Launches need permission too

Do you think the US government that's fawning over StarShield and the Golden dome is going to prohibit it? Of course not. And the permissions required for a launch or series of launches are VASTLY different than the permissions required to get something built. I spent my old life dealing with the FAA a lot. It's painful, but it's not terrible. You basically do their job for them by following their evaluation rules as you write your proposed operations up (they publish those in something that used to be called the 8900.1), then you wait and they stamp it or it goes through a series of revisions, but the time it takes is not immeasurably bad. Other departments and divisions of the government are not like that.

>And here's a version with no is or ought: Anyone whose goal is avoiding datacenter downsides, that could say "we forbid polluting and power grid draining datacenters here" but chooses to say "we forbid any datacenters here, go to space", is a moron.

I guess time will tell who is right. Still, the permitting costs and the time it takes will be the deciding factor in the long run. We're (that is the collective we as a people) are going to do this. We will have compute in space. Mark my words.

And "is a moron" is a bit of an overstep, unless you want to call the vast majority of people morons, which may be fair, but they're datacenters are the current zeitgeist's nuclear power plants in my experience.

> Companies almost always do what's cheaper. Your logic is incomprehensible here.

Opportunity cost is a big thing, and again, how many companies have you worked for? How many companies have you run? Just a window into my world. I just spent like 3 hours on the phone with the IRS today. It was cheaper for me to do that than to pay someone to do that, so I did. But I'll tell you, if I have to do this again I'm going to have my CPA do it. Time has a value too - it's almost more valuable than money. If you have to wait for the permitting process or just start launching datacenters ASAP, what's the "smart" choice? Well... I'd rather pay more now, and have that big compute without the headache than wait. I reckon it's not all or nothing either, we'll have space based datacenters and orbital datacenters and probably remote / rural datacenters too? But I bet we'll have them all.

We will see who is right here.

> A baseless claim.

Try to go get something big built somewhere, I dare ya. Shit, I live in Alaska which is notoriously permissive when it comes to development, I saw people TODAY on reddit squawking about a plan for a datacenter in the high arctic. I think the high arctic is a stupid place for a datacenter for a lot of reasons (basically most reasons other than cooling and cheap dirty power) and I don't think one would be built there for just logistics reasons alone, but people who will never go to those places (by the way, I've spent much of my adult life working in rural Alaska) will scream bloddy murder and fight tooth and nail to stop that project. I guarantee it.

How what kind of bandwidth are you saying a hypothetical West Texas datacenter would be able to get? How many batteries and how much solar? If you're going to take water from an already parched area, who has the water rights? You ever tried to get something built in the desert? These are all permitting hurdles that have to be stepped through point by point and approved by team after team of bureaucrats.

If the prize is "AGI++" or whatever we're calling super-intelligence in a few years, then the delay is more costly. But again, I just think, and no offense here, but you don't understand the logistical and permitting burden of building in the middle of nowhere. If you already own a rocket company, and you're launching something close to an orbital datacenter node already (starlink), then dealing with the permitting and stress from building outside Tempe, or the uncertainty of Tunisia or whatever is a nightmare. You're just going to go "up." And like I said, you can disbelieve me all you want, but I bet this is how things go. In fact I'm planning on it.

I bought land in the "middle of nowhere" last year to build our cabin on. I bought someplace with literally no-zoning/restrictions on purpose, but even on the land I bought I couldn't just pop up a multi-thousand square foot datacenter without a lengthy permitting process. Hell, even here in Alaska the permitting process for a running water is (rightfully) no joke.

I'm not trying to be an ass, but as someone who owns an (admittedly extremely small) business the opportunity cost of wading through the morass of paperwork and approval is just not worth it if I were trying to do something big. If I already had a space company, orbital datacenters would be the natural choice if I wanted more compute.

But again, we'll see who's right here.

I know land permitting can be extensive, but my bet is that it's a small effort per petaflop if you go to the friendliest location in 5000 miles and do it in bulk.

And launching enough rockets to compare to such big datacenters not only needs flight permission, it needs a lot more launch pads. And you need big assembly lines no matter what, so you can't avoid land permitting.

The way I look at it, land for the actual datacenter isn't a delay. Start that permitting at an appropriate time in your process and it'll be done before you're actually ready to build.

But yeah, we'll see.

I'm also assuming designs with no water use for this hypothetical. For bandwidth, you can drag some fiber out there easily, and for big AI tasks you don't need a very high bandwidth to compute ratio. (If you needed tons of bandwidth space would also be a problem.) For batteries and solar, you need massive solar factories either way so this doesn't change things tremendously much.

> And "is a moron" is a bit of an overstep, unless you want to call the vast majority of people morons

I think most people would allow a datacenter that isn't using electricity from the grid, isn't consuming water, and isn't polluting the air or with noise. Am I wrong to think that?

So there is a problem to be solved. Great! The history of human spaceflight is pretty much: Problem -> Difficult to find solution -> Solution leads to better spaceflight -> Solution leads to better life for humans on Earth. Then repeat that cycle for each new problem. Think of the new medicine and hospital protocols that are waiting to be developed as biologists explore the solution to this problem.

Couldn't agree more. But I'd recommend solving the problem before shooting ten men and ten women into the Martian regolith forever and telling them to make babies. Alternatively, it's not the scale of problem you try and solve fifteen timeslipped minutes and (at least) eighteen months away. We're not even sure what the shape of a solution even looks like, apart from "Generic Future Technology Tree Numbers 4 through 9…

Indeed, and that’s why we’re starting sensibly with a lunar colony…

I think you’re also exaggerating those issues considerably.
