I'm a Linux noob that started with CachyOS earlier this year to jump to an atomic distro recently. like a month ago give or take. I chose Bazzite though. context, am gamer, my PC is mostly for gaming and entertainment.

idk if I like it though. it's one thing to learn all the normal Linux things I can do, and sometimes need to do, but to add the atomic / immutable concept layer is a bit discouraging to me.

I'm thinking of going back to a non atomic, but wanting to try fedora based Nobara next

They have not, they do accept AI contributions, however their policy is a bit more restrictive than Debian's in that Fedora at least requires contributors to disclose LLM use in pull requests.

There are a few distros that do reject all AI code, which you can find in these two lists:
