I hope that snaps, flatpaks, AppImages, etc., will make a big difference in terms of adoption and ease of use. As @[email protected] said, if complications arise while trying to install or use software, then you're basically screwed unless you have a really good tutorial or deep knowledge. I've been using various Linux distros as daily drivers for the past ~10 years, and in that time, I still haven't figured out why there's such a big emphasis on compiling software. Your average Windows user has probably never even heard of compilation let alone been required to compile software in order to use it. For better or worse, the emphasis in Windows is on shipping binaries that the user can simply double-click to run. And if we want to reduce frustration for new Linux users, we can't expect them to know how to compile software. Snaps, flatpaks, and AppImages definitely move us in the right direction even if there's a lot of internal debate about which of those is best.
It's also nice to see big flagship projects like Gnome finally really taking off in terms of quality. Of course, the Gnome desktop environment won't appeal to everyone aesthetically, and it's generally much more resource-intensive than Cinnamon, KDE, XFCE, LXQt, etc.; but distros like Ubuntu, Fedora, Pop!_OS, etc., look really great and work really well out of the box for most people. Same with Linux Mint. And I personally don't care for KDE, but it's another DE that's pretty solid.
