Maybe it’s because Elon is too busy rattling off on Twitter and building trucks that rust after a couple of days.

SpaceX is not getting people into space, and certainly not to Mars. It’ll be a long time before we have someone who’s level-headed enough to make such a feat happen again. Even if resources were more limited back in the late 60’s, what made stuff work is people knowing how to use the tools they had. Now, we have all this stuff, and nobody with the knowledge to give it any use. It is rocket science, and big, fancy computers aren’t going to do anything if you can’t write the software for it.
