Sure humans should expand to mars. But Musk isn't getting any credit as a visionary here by just repeating what science fiction writers and cosmologists have been saying for decades.

Perhaps that to write about made-up achievements and amazing sciencey things is hard, but it's nothing compared to, in fact, in truth, actually achieving amazing things.

I agree with the idea, humans should aim to be a multiplanetary species. Musk isn't wrong about that, the problem is his plans to do that are as I said "all sorts of retarded" because they are essentially logistically impossible. Even if we ignore economics.

Thank Yahweh that you and so many others are there to explain things to Elon "all sorts of retarded" Musk.

You want a million people on Mars within 20 years. There's only about 13 launch windows in twenty years. Assuming you build rockets that can hold 100 people each. (Which we've never done) we'd need to be sending about 770 rockets there during each launch window, that's not even considering supplies.

A million people on Mars within 20 years does seem overly optimistic. I can't imagine that hundreds of humans at a time(!) can safely travel to Mars within the next few decades. It will likely take much longer, and it will be very hard, and it will often seem impossible, and there will be failures to boot (bringing schadenfreude pleasure to useless mediocre-minds), ... and this is also why the sooner we start resolving the huge obstacles ahead, the better. Humans spend so much more thought, work, money and resources on so much pointless (or, rather, shockingly idiotic) crap (make-up, etc.), than on space exploration and colonisation.

At the moment we've managed to send a grand total of zero. And time is running out for his initial promises there. It's not going to happen. It's a pipe dream. Musk is just a marketing guy who builds hype to attract investors.

Ah, yes, of course, and thank you again for joining that chorus of geniuses warning us of what an empty-promises marketing charlatan Elon Musk is.
