| These kinds of caps have for years been a dampener on human flourishing. My observation has been that those in stagnation or decline tend to attach themselves to these desires to hold the status quo. Anti-energy, anti-housing, anti-industry and so on because they've reached a local maxima in their ability to live and have chosen to spend their life in leisure. But there is the rest of the world, and if I'm told that the Africans should not have access to high-speed satellite Internet[0] so that the Europeans can use one specific method of looking at the stars, I don't find that convincing. In time, as we expand, space-based observation will become fairly feasible for everyone. And the satellites we have will decay to the Earth should we fail to keep them up there. We will build Earth orbital structures and swarms, and we will build Sun orbital structures and swarms, and we will go to the stars, and it will be better for humanity as a whole. 0: https://www.economist.com/middle-east-and-africa/2026/07/02/... |

| I think that "Africans should not have access to high-speed satellite Internet" is something you've just made up; the article you link talks about African people turning to Starlink because of local infrastructure issues, and the original article notes that the current satellite count is currently around 14k satellites. 100k is more than enough satellites to provide high-speed satellite internet globally. The article makes mention of specific endeavours, like the night-time mirror satellites, which are particularly disruptive to astronomy, and the general risks of high numbers of satellites. The ability to do Earth based astronomy is something that is of value to all the peoples of Earth, and is mainly funded by the western nations because of their current position as the people with more money. |

| ▲ | JumpCrisscross 2 hours ago | parent | next [-] | | > commercial launch engineers are optimizing for the lucrative satellite business, not larger and higher payloads Commercial satellites are getting bigger and heavier. Launch that can put big and heavy in LEO can put big and slightly less heavy higher up. Add to that things like in-orbit propellant transfer and there is a good chance astronomy sees a golden age in the coming decades (in countries with space access). I’m not dismissing the problem. Just this analysis as meriting any conclusions. It’s a start. But it’s only part of a full model of how these changes would affect astronomy. | | |

Some sort of modular telescope array that could be launched in pieces and self-assemble in orbit. Something that improves in capacity as more pieces are added. Everything seems to have stalled in this field, as if it's just waiting for a Starship which may never come. | | |

Building a scaling production system for Falcon right now would be silly. And if Starship never works out, we probably don’t see millions of satellites. It’s a fundamentally tied problem, which is why I say the analysis is incomplete. |

Here's a visual to consider the implications of things you can do with actually one million satellites of the kind of size scale being discussed: https://raw.githubusercontent.com/BenWheatley/blog/refs/head... | | |
| ▲ | JumpCrisscross an hour ago | parent [-] | | > Yes, they really would be this closely spaced: Earth's circumference is 40 million meters Satellites don’t orbit on the ground, which makes the 40m spacing nonsense. And nobody proposes putting a million 120 kW satellites in a single orbit. They really would never be that closely spaced. To approach those densities in a single orbital shell you’d need hundreds of billions of birds in orbit. Spread across all of LEO (and only LEO) we’re talking orders of magnitudes more satellites (like, quadrillions). | | |
| ▲ | ben_w 4 minutes ago | parent | next [-] | | > Satellites don’t orbit on the ground, which makes the 40m spacing nonsense. Hence why the horizontal scale bar says "40 m to 43 m": Going to 500 km doesn't add much to the orbit's circumference. > And nobody proposes putting a million 120 kW satellites in a single orbit. One of my tentative conclusions is that it would be an improvement if they did. It's in my blog post because I'm considering all possible arrangements of ways to do this. Current list: • Spread them out by altitude while still keeping them in sun-synchronous low earth orbit like SpaceX plan
• Put them all of them in a single sun-synchronous low earth orbit so none of them can hit each other
• Spread them out like Starlink currently is
• Have swarms, where each group has many satellites significantly closer to each other than the usual safety separation, like Google's Project Suncatcher
• Have fewer, bigger satellites, like Starcloud
> To approach those densities in a single orbital shell you’d need hundreds of billions of birds in orbit. Spread across all of LEO (and only LEO) we’re talking orders of magnitudes more satellites (like, quadrillions).Matters less than I expected when I started writing. How much so depends on what I end up adding by treating gaps in "full" (up to the safety margin) orbits as the thing of interest and seeing if someone's done a version of this on spherical geometry: https://math.stackexchange.com/questions/270937/how-can-you-... | |

We may get that, but only if the ruling class want what the Victorians called a "folly": https://en.wikipedia.org/wiki/Folly AI is wildly, wildly divergent in the possible futures it brings. It's really important to influence what happens, but don't limit the potential downside to only as bad as feudalism (neither neo-feudalist nor re-enacted): much worse monsters exist than the typical feudal lord.

That is why I'm against the data centers If you really believe this (and I’m not saying I don’t, I just don’t have confidence in it), blocking domestic. datacenters doesn’t preserve that labour value. It just ensures whoever builds those datacenters controls production from afar. Like, if AI really replaces human labour, does Africa and Europe having few AI datacenters protect it from America and China? Of course not. Not outside a symbolic level that even then would have to exist with the implied consent of the powers who produce. | | |

| ▲ | JumpCrisscross an hour ago | parent | next [-] | | > we're already in this situation xAI’s datacenters aren’t currently measurably replacing labour. So no, we’re not. If AI becomes economically competitive with broad sections of human labor, those who control it do have the power to replace humans. But banning domestic datacenters doesn’t stop them from existing; it just stops them from existing here. If that precondition arises, that’s just a recipe for domestic deindustrialisation. If you believe AI will replace human labor, blocking datacenters is silly. You want labor (or the public) to build and control them. I’m not convinced AI will replace labor, so I’m not yet at that step. | | |

In other words, having more AI datacenters under your jurisdiction might or might not provide a meaningful ability to regulate in a way that shapes the impact of AI on the economy. (I do agree with you that it's almost certainly a good idea to have them though.) | | |
| ▲ | JumpCrisscross 6 minutes ago | parent [-] | | > the point being made regarding xAI was that even if the datacenter is local that doesn't necessarily result in any meaningful difference Oh, absolutely agree. But the datacentre in Memphis is within its jurisdiction. If Nashville decides to stick it with a tax to fund a UBI, they can. Sacramento and Columbus don't have that option. To be clear, I am not arguing for more datacenters being built the way they are being built. But if you believe AI will replace labour, you want to control those datacenters. Blocking them explicitly cedes that control. |

It is not hard to see things from this perspective when a significant portion of writing is becoming obvious slop, and your liberal friends are having a hard time getting hired or landing writing deals or selling artwork.

Someday, that will include me, but hopefully not today, and thanks to modern medicine, hopefully not any time soon. The idea that the only way an artist should be able to justify their right to survive is by shitting out jpgs on fiverr or whatever is as absurd as the idea that that was somehow meaningful work.

Instead we sat outside and watched dozens and dozens of fast-moving stars zip around on all sorts of trajectories. I'm not saying it ruined the experience (I'm not an astronomer, and it was kind of fun.) But it really brought home how fundamentally we've changed the sky. I also hope we're able to lay enough fiber in developing countries that this many satellites don't need to stay up there forever. |

By all means, build what you like, but you don't get to dump your externalizations on everyone else. There is no 'We' in your projects, you don't speak for us. |

| This is a good point. A similar thread that links your examples together is how we all want to be the last person up the ladder. The last person to move into some neighborhood or into the last apartment complex. Or into a country. The last person to have internet access. Now we want to freeze how it is. Everyone after us threatens our experience. An American with access to good internet for decades is annoyed that their stargazing session isn't what it used to be now that the city is growing and creating more light or that other people are getting to tech up. |

| In related news, earlier this year Chile cancelled plans for a gigawatt-scale solar/wind powered hydrogen production plant nearby the ESO facility in the Atacama desert after light pollution complaints from European scientists. |

| Well, if you build too many satellites in the swarms, at some point you will lose the ability to see or go to the stars. |

| Moving all of astronomy to space based observations is entirely incompatible with the way that instruments are funded, built, and deployed. It is only valid for a set of highly specific and well funded observatories that take decades to get off the ground and can never be updated, improved, or modified to search new scientific directions. Why don’t “we” just build more cell towers? |

| ▲ | JumpCrisscross an hour ago | parent [-] | | I am aware of no orbital solutions for a catastrophic Kessler cascade in LEO. The only place you could engineer one is in GEO, because that’s a singular orbit, not a plane much less a volume. | | |
| ▲ | stouset 26 minutes ago | parent [-] | | First, you never specified LEO, only “space”. Second, the situation is already so bad that current satellites in LEO already require active collision avoidance systems in order to avoid becoming sources of debris themselves. Starlink alone reports over 1,600 close encounters each week. | | |
| ▲ | JumpCrisscross 23 minutes ago | parent [-] | | > you never specified LEO, only “space” What I said applies to space, too, outside GEO, for the number of satellites anyone is currently talking about launching. > the situation is already so bad that current satellites in LEO already require active collision avoidance systems in order to avoid becoming sources of debris themselves They require collision avoidance to avoid being lost. There is no risk of a Kessler cascade in LEO right now and nobody who can do orbital mechanics is claiming as much. We’d need millions more satellites than we have right now to start approaching the point where atmospheric clearance falls below the rate of new-debris production. And even then, you’re talking about a problem in specific orbits for months, maybe years. In the meantime, you get to allow nature to reclaim huge amounts of land from cell towers and conduit. |

| The "let builders and capitalists do anything because the future will be better for it" isn't a technically considered position. It's a tautology. |

| > These kinds of caps have for years been a dampener on human flourishing. My observation has been that those in stagnation or decline tend to attach themselves to these desires to hold the status quo. Anti-energy, anti-housing, anti-industry and so on because they've reached a local maxima in their ability to live and have chosen to spend their life in leisure. This kind of attitude has for millenia been a dampener on human flourishing. My observation has been that those without empathy or foresight tend to attach themselves to these initiatives to obliterate our shared human heritage to satisfy their own ridiculous misconception of progress. Anti-intellectual, anti-curious, anti-social and so on because they've reached a local maxima in their ability to give a damn about what it means to live a good life and have chosen to spend their life in self-satisfied ignorance. |

| Maybe a fair allocation of sattelites would be proportional to the number of citizens with voting rights in the country. Maybe with some modifier about how impactful that voting can actually be (eg. citizen initiatives vs. just electing representatives from a preselected pool). |

| “Anti” is a kind of super-meme that took over discourse in a lot of spheres, especially anywhere near academia, starting in the 1970s. If I had to trace it to one source it would probably be the Club of Rome and Limits to Growth. Paul Erlich would be a close second with The Population Bomb. Here’s a great podcast on the latter: https://www.youtube.com/watch?v=Nn1gieFMuWI This stuff sounds right because obviously you can’t have infinite growth in population or resource use on a finite planet. That means it won’t happen. The question is “how will it not happen?” The answer right now looks like “as people get wealthier they have fewer kids.” There are other possible answers like dematerialization of the economy which is also a thing. Before the 70s this stuff would have been called far right and identified with ideologies like authoritarian eugenics and fascism. The 70s is when a lot of “volkisch” proto-fascist and crypto-fascist ideas got a lefty hippie makeover. The other big one is the idea that “natural” is inherently good. I finally see this stuff getting some challenge from all across the political spectrum, even from the left. In previous decades you only ever saw it get challenged from the right or from what were once called libertarians. |

We should raise the bottom for sure but we definitely need to cure the degeneracy of the top too Technosolutionism is a cult. We either put the caps on ourself or nature will hard cap us anyways, in a much harsher way. |
