I think this is a very naive take.

* We can't really live on another planet in the solar system. * Look at how far the next star is and realise that we won't get there anytime soon (probably at all). * What's the point of surviving on another planet, without any other species? * Without considering the risk of nuclear war, we are in the process of destroying life on Earth.

The resources we put on that project are mostly wasted. We should try to live on Earth, I hear it's a nice place.

>> I think it's one of the reasons we have to be self sustaining on other heavenly bodies.

This is not a joke. But every time anybody brings it up a mob shows up saying that we must make it work here on Earth, and we should all go to hell if we can't. But we only need a few madmen in power for the rest of us to not matter.

Stone age? Hardly. More like 18th century.

I am more worried that we do not have that many attempts at rebuilding, because coal and oil are finite. OTOH a slower 2nd iteration might actually work better than this one.

> I personally think we're a button click away from going back to the stone age.

One reason to use less oil now is to perhaps preserve it in case we need to 'reboot' civilization in the future in case of a future cataclysm.

We were only able to reach beyond (near-)subsistence living because of cheap energy, first coal and later petroleum. All the easily accessible stuff is now kind of gone, so if there's another collapse (which may be more likely to be global in nature: see pandemics), then depending on how much knowledge we lose it could be hard to get back to the say level without the previously cheap/easy energy.

In past collapses (Europe: Western Roman Empire, Black Death) we were able to eventually recover because we at a simply technological level that could keep going even with the loss of a lot of knowledge.

> I think it's one of the reasons we have to be self sustaining on other heavenly bodies.

I think this will be impossible given advanced countries can't even be self-sufficient on Earth.

Is there oil on those heavenly bodies? Probably no, so you're importing your lubricants and seals/o-rings. Advanced fabs? No? Well you're importing your electronics. What kind of silica is there, because if you don't have the right kind of sand, you're mot making your own solar panels. How much radioactive material (uranium, plutonium, thorium, etc) is around if you want to try nuclear power.

> And also why wars or proxy wars between nuclear powers is extremely foolish and should be stopped with great urgency.

The strict interpretation of that foreign policy is that any nuclear nation is free to invade any non-nuclear nation and abuse its citizens.

Where do you draw the line? If for example an ally is invaded by a nuclear nation. Should you intervene or just call peace?

Does the rule-of-law between countries have any relevance?

So like usual I offer up "what's your alternative" ? Is it to ignore Russian's invasion of countries? Ignore Iran's chaos it wants to sew constantly in the Middle East? It's easy to say "just be peaceful" but history shows that countries are not peaceful towards one another, they constantly want to take other's resources, or force their way of life on others, or settle some vague issue they have with another country (or people there). I think most people would love if countries would just stop attacking others. right now we don't have the tech to live on "other bodies", that is pie in the sky. I would love if nation-states just stopped the nonsense and were good to one another and their inhabitants, but that has never been the case.

> I think it's one of the reasons we have to be self sustaining on other heavenly bodies.

But who will inhabit those other bodies? Humans? The same species that destroyed earth in your scenario? What makes you think that living on Mars would suddenly make everybody peaceful and enlightened?

Humanity en masse are superficial ignorant pretentious idiots. They are so pretentious that they pretend they are not pretentious and they care a lot ('It is utmost important for us [arbitrary lie here]'). Except Trump kind of people. They honestly and proudly announce that they give no fuck about anyone but themselves.

Yeah, this is also a big concern of mine. Nuclear weapons haven’t been used since ww2, but there also hasn’t ever been total war between two nuclear powers.

The current climate in Russia and the Middle East may change that.

Yeah, we should just stop all wars. Great idea! How has nobody thought of this before???
