@gamingonlinux So many things:

- Proton, due to Valve investing on the Steak Deck
- Flatpak, for installing distro-agnostic apps
- Flathub, for having a neutral place to put flatpaks
- Containers, to make it easier to reproduce software stacks locally
- toolbx & distrobox, for making stateful containers easy
- GNOME's community outreach with libadwaita & GNOME Circle apps
- Atomic distributions, for a tested set of software & rollbacks
- More app availability (both FOSS & proprietary)
