All of these distros strive to solve the problem with having multiple versions of libraries and programs coexisting without conflicts, but Gobo took a different approach. What Gobo doesn’t do is the declarative system configuration. In Nix you don’t need to worry about breaking your system because you can easily restore the previous version of your config. In traditional distros you would need to set up package manager hooks to make snapshots and create snapshots manually every time before changing something in /etc
It’s beyond my mind that x86(-64) survived to this day. It’s so inefficient
Edit: to clarify: I know nearly nothing about processors, so maybe the architecture isn’t really that inefficient. All I know is that after Apple switched to its own ARM-based chips, the programs could run faster using the same or less energy. Even with the compatibility later
