To be fair, SpaceX hasn't cut costs by an order of magnitude. They've made things significantly cheaper, but the list price for a barebones Falcon 9 is about $50-60m, while an Atlas V is around $100-120m.
Well, they’re targeting launching much more mass than F9 for a much lower cost with Starship (<$10M). So not done yet, but it seems like they have a good shot at it. And if they pull off orbital refueling, then they can take those huge amounts of mass to geo and beyond.
Yeah, you're right, I put some "haven't quite happened yet" stuff in there, but the point I was making was that there was a time when discounting the man was the rational thing to do, at this point I think he's proven his ability to do what he says he's going to do, and the ones I stretched a little are well on their way to happening.
