How would they make money from an operating system?

I hate to even put this out there, but "OS-as-a-subscription" (OAAS) could be a way. Your Claude payment covers all the software running 'your' computer, plus the ability to develop new 'apps' for specific needs on the fly telling the OAAS computer in human language what you need. Throw in services like email and cloud storage and some customers might find such a bundle attractive for the right price. It would suck revenue away from MS, Apple, Google. Enough to justify this valuation? No idea.
