> The amount of material resources in space are breathtaking. Asteroid mining has the potential of delivering multiples of the amount of elements we've mined for our entire history in single asteroids. That alone could sustain a space economy. At immense, non-economical cost. This idea is great in sci fi but we have nothing close to the technology to pull it of cheaper than mining things on earth >There also isn't our massive gravity well. If you have materials (see point 1) it is easier to build large installations. Point 1 is still sci fi > We should be able to build GIGANTIC underground habitats in the moon. Immense cost for no benefit > There was also the powers-of-ten energy use as we climb Kardashev levels. That only happens with space settlement. ... and significant advancements in energy generation / capture > Space will come more easily with cybernetics. More sci fi non existing tech > In a hundred years humans may be very very very different. Sci fi > But ultimately your comment harkens to the lack of vision of humanity, mostly I view it as a sign of increased control by the leisure elite over the world. They control the money and politics, and all they want are status and enjoyment, and the rest of the world to support them. Ok and your vision of what we need to be doing now seems to consist of liking science fiction and ignoring realistic constraints.
