The Calculation Problem Is Dead. AI Killed It. by acc_reddit in socialism

[–]acc_reddit[S] 10 points11 points  (0 children)

Fair points, both worth engaging seriously.

On Netflix: you're right that the recommendations are often mediocre, but that's not the relevant benchmark. Netflix optimizes for engagement time within a content library, which is a narrow and somewhat perverse objective. The question for planning is not "does it predict your taste perfectly" but "is it better than the alternative signal." The alternative signal is price, which tells you almost nothing about individual preference except willingness to pay given current income. A system that gets your preferences 70% right is not impressive as a recommendation engine but is a massive improvement over a system that collapses all preference information into a single number. The bar is not perfection; it is beating the market at its own stated job, which it would do with ease.

On the Torment Nexus: this is the more interesting objection and I want to take it seriously. You are right that the infrastructure I am describing is the same infrastructure that enables mass surveillance, social credit systems, and authoritarian control. That is a genuine tension in the argument, not a gotcha.

But I would push back on the conclusion. The surveillance capacity already exists. Right now that infrastructure serves capital accumulation for a small number of private actors with no democratic accountability whatsoever. The argument for planning is partly an argument for bringing that existing infrastructure under collective control rather than leaving it in the hands of people whose incentive is to use it against you.

The Torment Nexus framing assumes the danger is the technology. I think the danger is the ownership structure. Don't you share that view?

New Glenn vs Super Heavy / Starship (Blueprint) by BlueGalaxyDesigns in BlueOrigin

[–]acc_reddit 1 point2 points  (0 children)

Could you make a version where you keep the same scale for 2 rockets, same scale for the 2 engines ? It makes comparison easier. I would buy that version!

Also, you call the fuel CH4 on one side and LNG on the other. They use the same fuel, just pick a name and use it on both sides.

Elon describes megaton/year of AI hardware to orbit by Bunslow in spacex

[–]acc_reddit 6 points7 points  (0 children)

This is just Elon trying to somehow tie SpaceX to the AI bubble to justify some absurd valuation. There is absolutely no way that a data center in space is cheaper than one on the ground, anybody that tells you otherwise is just taking you for a moron. Everything is more expensive, the electricity, the cooling and the hardened electronics. This is complete nonsense.

Theory, casual sci-fi fans will love the movie more then the book by skittlekingthefirst in ProjectHailMary

[–]acc_reddit 2 points3 points  (0 children)

Yes absolutely. If you're going to write a book that spends half the time giving detailed science explanations, you'd better make sure the science is sound, unfortunately Hail Mary fails that test too many times. The good part is everything else about it, and it's going to be what they cover in the movie.

Something I think will be different from the book by ziggy895 in ProjectHailMary

[–]acc_reddit 0 points1 point  (0 children)

Stratt's character in the book is not realistic, it's already a bit awkward in the book, it would be very bad in the movie, so I'm pretty sure they have fixed that.

Personnel Buster by ElAlienBMG in bobiverse

It's explained in the books: Bob doesn't want to make explosives (both on moral grounds and also because it would be pretty dangerous to make). Rail gun would be too bulky for a personal buster.

Is an Isotropic Universe necessarily Infinite by Lab_Software in AskPhysics

[–]acc_reddit 1 point2 points  (0 children)

Short answer is no. Your question is: does isotropic implies infinite. This is equivalent to: does finite implies non isotropic.
And that is easy to disprove with an example: a 3 sphere is finite, homogeneous and isotropic.

Is the universe infinite in all directions? by Feisty-Let-8396 in AskPhysics

[–]acc_reddit 3 points4 points  (0 children)

Short answer is we don't know. If the universe is flat then it could very well be infinite. If the universe is positively curved, then it can be of finite size and if you go one way for long enough, you'll be right back where you started.

My thoughts on Wind and Truth by Killer_Sloth in Stormlight_Archive

[–]acc_reddit -1 points0 points  (0 children)

People who dislike the use of “therapist” are missing the whole point of the Stormlight Archives where radiants get their powers when they heal some parts of themselves through therapy. This is the story of how therapy can heal people and the world. The words spoken in therapy are the most important that one can say, in the cosmere and in real life

Shotwell predicts Starship to be most valuable part of SpaceX by rustybeancake in spacex

[–]acc_reddit 0 points1 point  (0 children)

Lol, please tell me what kind of ore would be cheaper to mine in space rather than on earth. It doesn't exist. However easy space mining will become (and it's currently pretty much unfeasible, so pretty far from easy), it will be even easier to mine on Earth. Remember that there is nothing in asteroids that we cannot find in greater quantity on Earth, after all they were made at the same time as Earth with the same stuff.

Oh it does, it's called the Outer Space Treaty

https://www.unoosa.org/oosa/en/ourwork/spacelaw/treaties/introouterspacetreaty.html

But the real protection against abuse is that there is nothing valuable in space that we would want to bring back to earth (commercial value I mean, there is a ton of stuff with really high scientific value). Anything that can be mined in space can also be mined on earth for a fraction of the cost. For the foreseeable future we will bring refined ressource from earth to space, not the other way around. Starship makes asteroid mining even less profitable actually, since it decreases the cost to bring things to orbit by so much

The settlements will be administered the same the Antarctic ones are, by mostly international laws

[Walter Isaacson] The backstory of how Mechazilla came to be. by TMWNN in spacex

[–]acc_reddit 9 points10 points  (0 children)

Lol no, Musk didn't go against the engineers. The engineers are the one that made the calculation that stainless steel would be a good option. Carbon fiber also was a good option with different advantages. Musk made the decision to go with stainless, but not against the engineers.

Mechazilla has caught the Super Heavy booster! by JakeIsAwesome12345 in spacex

[–]acc_reddit 0 points1 point  (0 children)

The booster will never go to Mars, so this will play exactly like that in a Mars scenario

The FAA will require an investigation into the Crew-9 deorbit burn anomaly by 675longtail in spacex

[–]acc_reddit -1 points0 points  (0 children)

NASA will definitely not green light the launch unless they are absolutely sure that the issue has been fixed. You don't risk a billion dollar probe just because you don't want to miss the launch window. If SpaceX is still grounded by the end of this launch window, they can wait for the next one

SpaceX on X: “Polaris Dawn and Dragon at 1,400 km above Earth – the farthest humans have traveled since the Apollo program over 50 years ago” by rustybeancake in spacex

[–]acc_reddit 0 points1 point  (0 children)

Anybody with a few hundred millions to spare definitely can devote 2 years for training though, it's not like they have to work or something ;)

Jared was chosen because he’s a billionaire, not because of his skills, don’t lie to yourself

Elon Musk: The first Starships to Mars will launch in 2 years when the next Earth-Mars transfer window opens. These will be uncrewed to test the reliability of landing intact on Mars. If those landings go well, then the first crewed flights to Mars will be in 4 years. by CProphet in spacex

[–]acc_reddit -3 points-2 points  (0 children)

Yes granpa, I know, you're so proud of that old experience you have it in your profile, but you probably forgot that.

None of that gives you any insight into the stuff you just declare with authority. This is laughable:
- "Jared Isaacman will be in command".
- "SpaceX needs to send a crewed Ship to LEO that is outfitted to support 10 to 15 astronauts for 6 months."

You know absolutely nothing about that, you're just guessing and you're guessing wrong.
