You make very well expressed and thought provoking arguments!

And while I can recognise myself in a lot of what you’re saying, I think that us millennials are just now beginning to reach the age (28 to 42 this year, by the definition I follow) where we have some weight to affect that system from the position in it that we grew up in.

Any of us who wants to make our own space: work on a good website, start a coffee shop the way we want it, run a node in a federated social network… I feel it’s not until now that any of us have had the skillset, long-term motivation and economical position to be able to do any of those things seriously. Building a better internet is what we are doing right here and now :)

True. Doing that wouldn’t be easy right now.

However, it doesn’t necessarily need to get back to Earth. If we have power up in space, it gets much easier to run mining operations on asteroids, the moon etc. As soon as we have both power and minerals, we can also start putting factories in orbit instead of on Earth, reducing energy need down here.

The stuff those factories produce can be dropped down to Earth, OR we use that stuff in space to build even more infrastructure. In fact, at this point it becomes feasible to build really nice space stations that people can go live on if they want. Eventually, we’d even have the production capacity to build O’Neill Cylinders.

Now we can just continue building and mining in space, while developing or preserving Earth as we like.

It sounds like they should be more careful with how they store their methane.

I do want to stress though, that I think that space technology is the single most important subject we can focus on, except maybe medical. If extravagant trips for billionaire’s can fund a bunch of it for now, that’s fine by me. Only really means that governments should be doing more.

Every day, the sun emits roughly a billion times more energy than the earth uses. That is, all our technology, all our food, all animals, all plants and all the energy needed to create all weather combined consumes about one billionth of the sun’s output. The rest is sent into deep space.

This waste of the sun’s energy is so vast, that we as a species absolutely want to start capturing more of it as soon as possible, rather than squabbling in the mud for fractions of the 0.0000001% of the sun’s output the earth uses today. Obviously we need our planet to survive until then, but getting proper infrastructure in orbit and beyond is such a massive game changer.
