At least the way I use AI tooling, it would be very difficult to accidentally plagiarize code outside of boilerplate I guess. The way tools like GitHub Copilot are really useful is when using your existing code as "reference", so if you use it to write a simple method, it's only going to be restructuring your existing code.
In other words, Copilot is basically just meant to be used as really smart copy-paste.
I think that it's worth trying both- Fedora is a little more involved than Mint but tends to ship the most cutting edge-stuff, whereas Mint is well-integrated with Cinnamon and fairly user-friendly.
I guess this isn't the end of the world for Nvidia users, because FSR 2.2 is pretty good, and this game will be unlikely to have ray tracing that requires a lot of upscaling anyways, but it still sucks that the only way games will run well on any PC hardware nowadays is if the developers are paid to optimize for it.
Although macOS holds a high market share, it holds a smaller percentage of Steam users than Linux right now. Essentially, there's more people on Linux known to buy games than on Mac (at least on Steam).
