It wasn't worth it, but it's 2026, not 1991, when Linus first released Linux. AI can shit out a new OS, given enough tokens, and a VM/compatibility layer would let you run Android apps until native ports became available. The question is why would you want to do that? Computers are vastly more capable than they were when the Linux kernel was originally designed, and the needs of programs and their permissions have changed as well. https://xkcd.com/1200/ While throwing away all the learnings and starting from scratch are usually not justified, sometimes it is the right choice, if enough things have changed. Should GPS location, fine grained or coarse, and related permissions, be a part of the OS kernel or a user space daemon that other processes can query or some other thing? That wasn't a question when Linux was created but should be a core consideration for a replacement system that was created today, along with a myriad of other modern day questions that didn't exist back then. I don't think it's a loosing game, and I don't have the resources to make one myself, but I do think that the world's materially changed enough to justify building a new one from scratch.

AI generating code changes the game significantly, though there are issues with that. A new OS would have taken several millions and multiple teams, but can now be done for far less. The problem is hardware to run it on. Who'd pay $2,000 for a shittier phone with less features when a $500 used one with GrapheneOS is right there? So the market, (in)efficiently, hasn't come up with a new phone OS. Not because it isn't warranted, but because the free market isn't a perfect system.
