"Just"... Considering that Earth-based heavy machinery needs fixing all the time (even in our much more benign temperature and presure conditions), a few humans would really have to be much more expensive than your steady stream of replacement machines.
Why billion? Those are rookie numbers. Amortize the initial investment with a trillion. Also, the iron will most likely be more useful in space anyway. Some other elements, perhaps not.
You mean the magical technology of picking up chunks of almost pure metal from the ground?:D Our distant ancestors had that. That's where they got their first iron, actually.
Well, apparently less than something like $15k/kg or so would be spiffy, as per the reasoning above. (Maybe you could go electric and pay below $150k/kg for argon instead?)
More accurately, you have twenty times more widely dispersed low-grade oxides that would require fucking up the whole crust and atmosphere that we live on/in to get to than 16 Psyche has 90% pure metallic material. How much of your stuff is practically recoverable?
It's NOT about exhaust velocity in this case. Most likely it's about thrust per rocket's business end's area which dictates the maximum height of the rocket stack that still lifts itself from the pad.
The asteroid belt consists mainly of the same stuff than the Earth Moon and the Earth's crust anyway, and the later have more of it.
Just a simple comparison of 16 Psyche with our recoverable mineral reserves betrays your deception. Just because Earth has considerable amounts of iron, nickel and siderophiles in its core doesn't mean that they're easily accessible - they're in the fucking core! You're *never* getting to the core.
The energy required to move something from the Asteroid Belt to the Earth is so high that the cost will by far outnumber the possible revenue for selling the stuff. Even if you mine an asteroid consisting of pure gold or platinum, you will pay more for the fuel to get there and back than you can possible sell the gold and platinum for on Earth.
I would love to buy me some platinum from where you're buying it. Apparently it must be super cheap compared to the price of some methane and oxygen. I would, however, not wish to buy any of your math or physics textbooks, apparently they're awful.
There is no practical reason to send humans beyond earth orbit. Robots don't need life support, they don't need expensive ultra-reliable gear, and they don't need to come back home.
Yep, it's great that we already have that AGI to control with low latency our newly invented unbreakable space mining equipment. Otherwise we'd have to send people along to control and fix things.
Perhaps, but the modern equivalent would be pointing to AGW denialists or anti-vaxxers or Apollo hoaxers and concluding that 21st century people were bad at science. I'm not sure that's how such general statements work.
Why would you label someone unable to change position when confronted with evidence as "extremely intelligent"? That sounds like contraindication for intelligence.
I wonder if they remember reading in history class that it was generally accepted that the earth was flat once upon a time.
Not only have we known that the Earth is round since the times of Ancient Greece, but we've had a reliable method for estimating its diameter since that time as well. Which makes me wonder what kind of weird history you were taught...
The current rise in temperature around the world is also adequately explained by our constant increase in energy production and consumption.
Anyone capable of producing such bullshit can't be possibly taken seriously. Anyone reasonable can compare ten terawatts with a hundred thousand terawatts and conclude that the additional direct heating caused by the former is ridiculously tiny.
We don't need to know *everything* about electromagnetism to understand that absoption spectra exist and what they do to physical systems. So, no, the nature of magnetism is irrelevant for this.
My country survived several decades, but how is your question in any way related to the claim of "no one producing anything" which I was responding to? That's a wildly different claim from yours.
I agree that the other examples are nonsense, though. "Five times lighter" would be a negative weight (the original weight minus five times the original weight)
Why the hell would it mean anything else than weight diminished by a factor of five? Even just common sense tells you it can't possibly be negative weight anyway, since there's no such thing. I swear you Americans are just trolling the rest of the world with this shit, since nobody else has any comprehension problems with that.

If that is true, then we'll have AGI in ten years or so? Awesome!
That's the stuff that you end up with, not the one you begin with.
You mean the magical technology of picking up chunks of almost pure metal from the ground? :D Our distant ancestors had that. That's where they got their first iron, actually.
In exactly the same way? The beginning and the end are always going to be the same, just the middle part is longer.
But you don't have enough carbon to reduce that metal. Carbon is much rarer than iron, for physics reasons.

Not likely. They already sent Pioneers to Jupiter and Saturn, not to Mars.
They ported LLVM to Rust already?
Arbeit macht bleifrei, actually.

Hold up, you are confusing correlation with causation here. There is yet any scientific proof yet that this is the case.
You mean other than over a century of repeatable lab experiments? And basically our entire understanding of electromagnetism?
And the socialist reality is you end up with no one producing anything
Funny how multiple countries survived multiple decades without producing anything. They must have had some secret magic...
and the illegals stop traipsing though this land leaving trash, dead bodies, fires and a basic ecological nightmare behind
A few centuries too late for that, don't you think? :-p
