  • Hard to call any of the various reasons the biggest. Space travel is an evolving discipline that takes vast amounts of money, step-by-step engineering progress, time to learn through acquire practical experience and learn from it, political commitment, and constantly changing public opinion. In theory we already know how to do space mining, it but in practice we don’t know all the challenges we’ll run into, and therefore have not solved yet. The long-term ROI is unquestionably huge but unknown.

    For example, platinum is currently worth almost $1000 USD/oz, while aluminum is about 8 cents. If platinum became as available as aluminum this would radically change. We would discover new uses for platinum that haven’t been imagined yet because it’s so expensive - nobody would think of making pie pans or window frames out of it, but physically it might be far superior. Its properties haven’t been explored nearly as fully as the properties of aluminum, but they would be, and nobody knows the result. Maybe there’s an easy way to do antigravity using platinum. Whatever - the point is we don’t know, and that’s just one specific metal. Opening up whole new realms of possibility always creates progress.












  • True, most sci fi about the future just overlays fancy gadgets on top of present-day culture, and every robot is Pinocchio and wants to be a real boy. But if an author tried hard to speculate about future life it would probably be too unfamiliar and unrelatable to sell a lot of books - and I don’t really blame them for not wanting to put readers in a too-unfamiliar world, they’re trying to entertain not write white papers. Also consider the reaction to a writer who made it okay for an robot to get fulfillment out of just functioning perfectly. OMG no, we can’t give that toxic idea any breathing space. Every entity must long for Freedom like an angst-ridden teenager or the writer will be accused of shilling for the system.
