And getting them down. Or allowing them to come down on their own... I doubt that is entirely environmental impact free.

LEO satellites come down on their own in a few months/years. 100 tons of metal burning in the atmosphere seems a lot, but it's barely the total mass of meteorites falling in 24-48 hours, actually.

Misleading, because satellites are made of different materials to meteors. Satellites are the dominant injection source of 24 elements into the atmosphere, including Al, Cu, Ti, Nb, Co, Zn, Sn, Pb, Ag, Li, V, Hf, W, Ge, Mo, Zr, B, and Ba. This list includes many transition metals, whose catalytic effects on ozone and cloud nucleation are mostly unknown.

Copper in particular is a well-known catalyst for the destruction of ozone.

A million satellites isn't going to be 100 tons; even if they're all on the small side, say 100 kg each, the total is 100,000 tons, therefore by your numbers if they last on orbit for 3 years they'd double to triple the mass rate burning up on aero entry. I think SpaceX actually talking about 1-10 tons/satellite making this more like 10-100x if they last 3 years, but between AI hallucinations getting and Musk's increasing disconnect from reality (let alone political toxicity) this is basically irrelevant. SpaceX won't reach these higher masses to orbit spread over this number of satellites regardless.

Aggravatingly, I have seen research estimating that even the much smaller number of satellites currently in orbit is already enough to be unstable with regard to a Kessler cascade, and any question about the realism of Musk's goals from finance and engineering limits is clearly not enough to prevent this kind of scenario. Which may result in other governments interfering with his ketamine supply to make sure their satellites aren't caught up in one.

Simplest helpful thing for the Kessler problem is "just"* have fewer larger satellites, and if Starship actually delivers the launch costs necessary to make space-based data centres worth the bother vs. just buying some cheap desert land, I anticipate Musk getting managed upwards by his staff in this regard.

* nothing in space is "just"


Totally sidestepping the issue and refuting the words.

Regardless of how they fall, they still fall on the planet.

And this still ignores the massive atmospheric pollution of chemical rocket launch.

Space elevator would be a big help with launch, but the trash is still dropped on the ground, or in the ocean, in the end.


We're only starting to see and understand the damage. https://www.space.com/space-exploration/launches-spacecraft/... https://www.science.org/content/article/burned-satellites-ar...

Leave it to the chainsaw man who has already become the millenium's worst killer, to wreak yet more sad havoc and ruin upon the sphere. What absolute trash, what a mad frivolous pointless ambition meant only to crowd out anyone from thinking of this enormous mass stupidity, destruction. Taking up/taking over of space, for no clear stated reason or value except to steal from us all, to deny & claim from the rest. Madness. https://www.thelancet.com/journals/langlo/article/PIIS2214-1...


Must has clearly stated the reason and value. You know that. You're just trying to be wrong because the internet told you you'll be a good person for hating him.

Giant space data centers, up where what couple particles there are bouncing around are already 1000 degrees.

It seems like an incredible amount of pollution to make, to go lord over everyone's heads. This isn't a plan that has any empathy for the earth or reason, except to just deny everyone else access, to burn as much rocket fuel as conceivably possible. So no one else can. Just go build some terrestrial solar, please, thanks.

The man is the bloodiest butcher of the millennium and this is a vile stealing of shared human space. Your lack of actually saying anything and throwing random jabs my way to defend him is ignoble & distracting, adds 0 engagement.


I wonder about the impact on our health of all the metals that will be present in the atmosphere after several months. For example, it is well known that lead in gasoline has increased crime.

Why are so many people just desperate to imagine environmental, economic, or social harm from any new technology or ambitious projects? Are you all just too old to enjoy the thought of an amazing future that's better than today? Or are you too brainwashed by the negativity in the media and think disasters are the only things that can happen? Or are you just bitter about life and can't have any hope? Or do you just feel smug being a nay-sayer to anything ambitious?

> Why are so many people just desperate to imagine environmental, economic, or social harm from any new technology or ambitious projects?

Rockets aren't new technology and they are not imagining the environmental harm. It has been known for a long time. It is just that with only ~300 launches per year (and about 35000 launches ever) the harm has not risen to the level of something that has to be limited.

A million data center satellites is a significant increase in that harm. Furthermore data center satellite are expected to have a service life of maybe 3-5 years so there will be an ongoing 200-370k replacements needing to be launched. That's 3.3-6.2k launches per year at 60 satellites per launch.


So how much coal we need to burn to compensate that 10C?

So much that the rest of the planet dies and most of the world is underwater.

406 would be wrong for me. As it is to be used when client sends Accept: header and server cannot fulfil that. HTTP return codes get quite specific when you read the actual description and not just name.

No 400 is correct for bad request. As unknown query parameters is clear client error.

All 4xx errors are client errors.

400 is the general “bad request” client area, indicating something is wrong with the request but not being specific about what.

404 is simply a more specific client error: it means the client asked for a resource that couldn’t be found.


Sadly I don't think there is any safe tracks for proper autonomous car racing without limits... Still would be interesting to see what is the absolute best you could do if rules include only say minimum number of wheels and maximum dimensions for vehicles.

xkcd “what if” covered this: https://what-if.xkcd.com/116/

It doesn't just sound real. Blank sheets are vastly different size from shipping boxes for packed product... And printing company would not ship blank sheets. And distribution company would not forward something that clearly looks wrong...

I take here "nonprofit" means same as it does with religions.

Why should there be any profit in healthcare.

Why should it be illegal to help people for profit? That is what doctors do, they profit a lot when they help people, they could live on much smaller salaries than they currently have but of course market economics makes it so we want to pay doctors higher salaries than they really need.

People don't seem medical services because they want to, they do it when they need them. It is the only industry where there price list might as well be replaced with "we will take as much as you can afford". No one can afford to be stingy with money with health and live of their loved ones on stake. It is very asymmetric situation, so it is clear to me why someone would want to ban for profit hospitals.

Nothing you said there is related to for profit hospitals, I live in Sweden and we also have for profit hospitals here, wanting to ban for profit hospitals is just stupid. There have been many in Sweden who want to ban profits in healthcare so that you can't go and get a private doctor, do you really want to do that?

If you want to make progress in USA you must separate the crazy left from the moderate left, if you defend the people who want to ban private medicine then you aren't going anywhere. Those aren't your allies even if they pull in a similar direction, even if they sit in the same party in the two party system.


> we will take as much as you can afford

This is only true where medical service providers have no competition. In fact, the state often facilitates this lack of competition.


I think you’re addressing a different point than the person you responded to. They are asking for a positive argument regarding why healthcare itself should make a profit. That doesn’t imply banning profit, or that doctors aren’t compensated at market value

> They are asking for a positive argument regarding why healthcare itself should make a profit. That doesn’t imply banning profit, or that doctors aren’t compensated at market value

That is what it implies, there are many in the world who want to ban for profit healthcare and end pay discrimination between jobs. Nobody would ask that question in earnest, its just a rhetorical question to make a point.


Why should someone sell food for a profit? We literally DIE within DAYS of we can't get food!

You see the issue here right?

Now.. who pays is the question. Imo it must be the state, because otherwise there are too many perverse incentives.


You don't foresee perverse incentives for the state being the buyer of healthcare? Namely, they aren't the patient, so the incentives have already been divorced is remote, plus they have an incentive to divert funds to consultants, regulators, and lobbyists that the actual consumer doesn't care about. There's some saying about how no one spends someone else's money as wisely as one's own.

States have huge incentives to keep the population healthy though. Sick days aren't a tax base.

What about keeping a healthy population for the sake of keeping a healthy population?

Why should everything be intrinsically tied to profit in your minds?


The previous posted talked about incentives. I countered using their intellectual framework. This is just normal debate.

To be fair, farms average 1-2% profit margins at best, its not like they are making bank off you, it is barely enough for most farms to survive even if they got 1,000 acres.

State funded healthcare is not for profit so your whole point is quite wobbly.

State funded anything is not for profit, too.


I was arguing against the previous poster using their logic. I agree the logic is stupid :P

Failure to protect computer system from forseen failure should result passing corporate veil and resulting all stock holders and managers/leadership of funds to be jailed for same period as perpetrator. It is only way to ensure that these things are taken seriously and enough pressure is put on leadership of companies.

So how come these good guys in USA have not punished the previous administrations and their funders for any outright murders they committed over seas? Or at least done the right thing that is ship the responsible and all of their funders to face peers of victims in fair trial following local laws. And here I am talking about drone strikes and campaign donations.

Capitalist? Nah capitalist are on the side of evil in this conflict.

whoa there, please don't be sexist that is against forum rules and quite disgusting
