Charles Stross isn’t exactly a fan of Musk’s, but he outlines why he thinks Musk is on a potentially multi-trillion dollar path:

So, I’m going to talk about Elon Musk again, everybody’s least favourite eccentric billionaire asshole and poster child for the Thomas Edison effect — get out in front of a bunch of faceless, hard-working engineers and wave that orchestra conductor’s baton, while providing direction. Because I think he may be on course to become a multi-trillionaire — and it has nothing to do with cryptocurrency, NFTs, or colonizing Mars.
This we know: Musk has goals (some of them risible, some of them much more pragmatic), and within the limits of his world-view — I’m pretty sure he grew up reading the same right-wing near-future American SF yarns as me — he’s fairly predictable. Reportedly he sat down some time around 2000 and made a list of the challenges facing humanity within his anticipated lifetime: roll out solar power, get cars off gasoline, colonize Mars, it’s all there. Emperor of Mars is merely his most-publicized, most outrageous end goal. Everything then feeds into achieving the means to get there. But there are lots of sunk costs to pay for: getting to Mars ain’t cheap, and he can’t count on a government paying his bills (well, not every time). So each step needs to cover its costs.
What will pay for Starship, the mammoth actually-getting-ready-to-fly vehicle that was originally called the “Mars Colony Transporter”?
Starship is gargantuan. Fully fuelled on the pad it will weigh 5000 tons. In fully reusable mode it can put 100-150 tons of cargo into orbit — significantly more than a Saturn V or an Energiya, previously the largest launchers ever built. In expendable mode it can lift 250 tons, more than half the mass of the ISS, which was assembled over 20 years from a seemingly endless series of launches of 10-20 ton modules.
Seemingly even crazier, the Starship system is designed for one hour flight turnaround times, comparable to a refueling stop for a long-haul airliner. The mechazilla tower designed to catch descending stages in the last moments of flight and re-stack them on the pad is quite without precedent in the space sector, and yet they’re prototyping the thing. Why would you even do that? Well, it makes no sense if you’re still thinking of this in traditional space launch terms, so let’s stop doing that. Instead it seems to me that SpaceX are trying to achieve something unprecedented with Starship. If it works …
There are no commercial payloads that require a launcher in the 100 ton class, and precious few science missions. Currently the only clear-cut mission is Starship HLS, which NASA are drooling for — a derivative of Starship optimized for transporting cargo and crew to the Moon. (It loses the aerodynamic fins and the heat shield, because it’s not coming back to Earth: it gets other modifications to turn it into a Moon truck with a payload in the 100-200 ton range, which is what you need if you’re serious about running a Moon base on the scale of McMurdo station.)
Musk has trailed using early Starship flights to lift Starlink clusters — upgrading from the 60 satellites a Falcon 9 can deliver to something over 200 in one shot. But that’s a very limited market
As they say, read the whole thing.
