Good for you. But Haiku (OS) is MIT licensed and therefore easily forked, and at this point the AI you dismiss as "Special Needs Wintermute" (much as I agree with the sentiment "You need to be able to explain your work without just pasting in what [it] says") is being used to find and resolve critical issues in OSes that actually get used outside of hobbies, and even when the AI was a lot more meh than it currently is, it has been useful for such hobby projects* when used by people capable of explaining as you demand.
* I like hobby projects, no shade here. But it is a hobby project, just like the people trying to keep RISC OS modern, or my suggestion about MacOS classic. There's no obvious reason to pick these things over "just use some flavour of linux" in the present world, unless you're a nerd like us.
Ironically, it being a hobby project might actually be a good reason to keep the AI away: the effort is the point.
