Nothing has, well, nothing out of it. On the software side, Nothing’s goal is to push AI into absolutely everything (Playground idea amongst other things). On the hardware side, their devices look awesome, but looks can only go so far without software.
GrapheneOS’s philosophy is the polar opposite of Nothing’s approach - many features are missing (and GrapheneOS users don’t really care about those), such as Google’s spyware and random AI slop through the OS itself.
