My best friend from high school did. Almost his whole family in fact (by different and unrelated endeavors). Not only that, but when he came to the US, neither he nor anyone in his family spoke any English. Five kids and two adults in three tiny rooms in a poorer immigrant part of town. He's now worth about $20million as is his brother.
His father owns a string of businesses across the US, his mother owned a restaurant and he has a sister with an MBA and who is a lawyer in Paris and Las Vegas. His other two sisters are well off ivy league educated accountants. And they did not win the lottery and are even brown. Go figure.
There was a study or two a couple years ago that indicated this was one of the major reasons for the perceived growth in inequality. Before you'd have doctors marrying across classes because it was socially acceptable, but now you ave doctors marrying other doctors, software architects marrying software architects and ditch diggers marrying other people from the same side of the tracks.
Ham radio is also 90% male and was teh tech before computers. This number has been consistent over the last 80 years and in every country and culture on Earth. How do you explain this?
But they did not expect to live in their boat once they arrived, never venturing out. They'd have a normal life like the one they left behind. Chopping wood, growing their own crops, chasing butterflies, swimming in lakes, having lots of kids.
Bringing a rock back was not the goal of Apollo. In fact, there were many at NASA who opposed doing so because it added risk to the mission. The first astronauts were prohibited from talking to any of the scientists because it might give them ideas. The core of Apollo was focused on Kennedy's challenge and little else.
Sure they are. Why send 3 people down in a submarine looking out a tiny window when for the same cost you send 5 rovs, each with a dozen ultra high definition cameras fed to 600 oceanographers over satellite links simultaneously all over the world working 24 hours a day? And have them spend months at a time at 4,000m. All deployed by a nuclear powered drone boat that comes to port every 5 years for maintenance and fueling.
If a cramped experience is required, then build mockup of submersible and have people sit in it while looking at porthole monitors.
At what time do you pull out until payoffs are more certain? Or do you throw money at it forever because of some quasi religious belief? Maybe we should e investing a few billions $/year on time travel, I'm sure that would have a much larger payoff than space mining.

This was Gödel's problem/insight.
Most He comes along with natural gas. It's also a fission product in nuclear reactions and decay.
Could we use space Thorium?
I used He3 in my lab (He4 also (refrigerators)). It cost a couple hundred $/liter.
Maybe you've watched too much 60's scifi.
Civilization is subjective. Not all civilizations are western.
What happens in a couple thousand years, you just change your mind?
Evolution is about survival of genes (dna), not species.
There will just be a new status quo. Nothing will change except for the names of the problems.
Richard Dawkins said that aging and death was one of the best evolutionary advances.

Look where we are today.

Yes, the same thing that makes ham radio operators a male activity.
Ham radio is also 90% male and was teh tech before computers. This number has been consistent over the last 80 years and in every country and culture on Earth. How do you explain this?
How many other countries have private companies that have put satellites into orbit?
But they did not expect to live in their boat once they arrived, never venturing out. They'd have a normal life like the one they left behind. Chopping wood, growing their own crops, chasing butterflies, swimming in lakes, having lots of kids.
Most technology development is due to war.
You want to talk joules(energy), not watts. And the energy requirement is ~33MJ/kg
Why?
More gooder.
If they hadn't brought a single rock back

How many Robber Barons can you name? Who was the first Europen to set foot on north america?
they aren't a replacement for going yourself.
Sure they are.

completely uncertain payoffs
At what time do you pull out until payoffs are more certain? Or do you throw money at it forever because of some quasi religious belief? Maybe we should e investing a few billions $/year on time travel, I'm sure that would have a much larger payoff than space mining.
They're pretty close. 1 gallon of gasoline is equivalent to ~34kwh. So about $3 of electricity for $3 of gasoline.
