>Where is... the vibecoded OS

This perhaps isn't an issue at any meaningful industry as I think there is little room in the space for a new OS to take off, but within hobbyist circles it seems it's becoming a problem. On subreddits such as r/osdev, a lot of interesting-looking projects are being called out for their code having a lot of AI hallmarks: commit history showing an entire OS with a shell and GUI being written in a week, almost exclusively very large, non-atomic commits, comments that randomly include words from a different language, and snippets of code that are blatantly plagiarised from well-known projects in the community.

It's such a strange thing to see, because it's an area of programming that has almost zero practical need these days. We already have three big desktop operating systems that cover 99% of use cases, and there are already projects that fill most other gaps. Unless you have a really specific problem that can't be solved by patching Linux, writing a whole new OS and everything that comes with it is unlikely to be worth the time. IMHO, the only reason to write an OS in current year is for the hell of it; if you're really interesting in programming and computers, you like solving problems, and you like building large, complex systems, writing an OS can be a really fun long-term project. If you do none of the work and simply leave an LLM to plan out the system and solve all the problems, you gain absolutely nothing from it.

If we wanted to replace any of these operating systems in 10 years, or needed to, the best time to start would be now.
