  • Better acceleration, steeper inclines, tighter curves at same speed, better ride quality and less wear. As someone has mentioned below, normal trains could go a lot faster than they do in practice, because the ride quality, wear and wind resistance get atrocious, and the tracks need to be exceptionally straight. Making a maglev go fast is more feasible, though you still have the wind resistance issue obviously.

    Yeah the artificial intelligence gurus are deluded. And don’t get me started on Kurzgesagt, those fucks think a couple of billion dead due to climate change is reason to be hopeful, and that Bill Gates’ investing in carbon capture is going to save the rest, because, err, magical thinking he gives them money.

    Launching spacecraft from earth and putting them into various orbits needs a lot of energy. It’s just going to be cheaper to mine stuff on earth or recycle. With fully automated robots and something as close as Mars and mining something super rare and valueable maybe, but it gets exponentially stupider when you need to send humans or go to another solar system.

    I appreciate the stab at the US empire, but if I may be serious for a moment: It makes no sense to come here to steal our shit when there’s countless stars and planets in the universe. I don’t even think it makes the least bit of sense for humans to ever go to Mars and mine minerals there, given the logistics involved. Any alien smart enough to come here is going to be smart enough to realize that going to the pub is way easier and more fun.
