If you are comfortable using fedora or if you are fine learning about fedora, use fedora.
I personally wouldn’t use Ubuntu with it’s recent controversy in specific the “explicit AI features” planned to be implemented within ubuntu. I’d suggest avoiding it out of privacy concerns even if it runs locally on your system.
the general trend for AI adoption, is to make it accessible for anyone to onboard, and then slowly control the users by (for example) making users connect to their servers to use their chatbot which then they can train, and have a better profile of you.
Canonical never mentioned that, in fact they mentioned quite the inverse. but any implementation of an AI chatbot, Tech companies aren’t doing it because of how revolutionary AI is. The AI is the product and your data is what they want.
I’m not saying canonical is pursuing that initiative, but that’s generally how it goes for most tech companies. Don’t take my word for it, ask yourself, “what service does Ubuntu provide? what financial backing (sponsorships) do they have?” I’ve looked far and wide and the only thing I’ve found is, they offer a free OS install as their consumer grade product, and a subscription service to their enterprise network that is clearly not a sustainable business model (from an engineering perspective) for a multi-thousand employee company.



if your trying to find an OS that is low on resources, there’s only one option: alpine linux. Yes it starts out as a TTY (no graphical environment) but they do have scripts to install the OS and a graphics environment of your choice.
the one concern is driver support, generally (unless using a popular distro such as zorin OS) driver support for Chromebooks are limited. I’ve tried getting alpine Linux on my Chromebook and can’t because the wifi card would not work for it.
that said, if you’re ready to manually configure driver support for it (which most likely will happen) the artix OS uses about 128 MB of memory. That said, if you have more, Linux will dynamically allocate more for core OS functionality
