Wouldn't the Steam digital demo system be the modern evolution of the shareware model? For free you can access a limited portion of the game to try it and consider eventually buying it.
This feels like a very high-tech solution to a problem that doesn't really exist. Why involve an LLM to install Hyprland when "sudo dnf install hyprland" works fine? I feel like you're mistaking Nix being 'AI-ready' as a feature, when in reality, you're just forced to use an LLM because Nix is too annoying to manage manually.
