Let's say just like for example like MacOS. It's awesome we have so many tools but at the same time lack of some kind of standardization can seem like nothing works and you get overwhelmed. I'm asking for people that want to support Linux or not so tech-savy people.
Software-wise, it seems that the relatively fast adoption of flatpaks and other containerized formats somewhat solves the typical dependency hell that was so common in Linux just a few years back (and to some extent still is an issue today depending on your distro and use case). The hardware support side is a little harder. That's going to be up to vendors to play nice with the Kernel team and/or introduce reasonable userland software that doesn't break the golden rule. Until Linux gets more market share the latter isn't likely to happen. A nice side benefit of the emergence of immutable and/or atomic distros is that users can play around and try things with much lower risk of bricking their systems, so I'd also consider that a step closer in the "it just works" department.
