I think you're massively over-generalizing here to make Linux look like an unstable mess. Rolling release distros are the ones that want you to read the patch notes. Arch is the poster child for those. Stable distros like Mint and Ubuntu and elementaryOS don't brick your system with every update. They hold back updates and stick with older kernels to ensure stability. Linux is, already, very good. It sounds like you haven't used it for any length of time. Valve's work on Proton has made Linux gaming viable for a whole lot of people, but the majority of computer users don't play intense video games. They want web browsing, email, office software, that kind of thing. Linux does those just great on almost any device all the way down to Raspberry Pi boards.
