It’s convenient. Can’t hurt to get used to it, for sure, in that it’s useful to not have to go through dependency hell installing things sometimes. It’s based on kernel features I don’t see Linus pulling out, so I think you’ll only see it more.
As someone who runs nix-only at home, I mostly use its underlying tech in the form of snaps/flatpaks, though. I use docker itself at work constantly, but at home, snaps/flatpaks tend to do the “minimize thinking about dependencies and building” bit but in a workflow more convenient for desktop applications.
My eve online circa 2008-10 was on Linux, as well as other not-entirely well remembered attempts dating back to around 2005, when I was more interested in spinny cube desktop. Fglrx and I were well acquainted, but not quite friends.
