Knowledge is great, but ignorance is bliss, I suppose :P
People really should know just a little bit about stuff they use every day.
Maybe the other developers disagree, but there are already plenty of Linux distributions that try extremely hard to be friendly and gentle, and remove needless technicalities -- and they even make it simple for developers! They could satisfy you or someone else! The developers put a lot of work into them, and that's really fantastic. But we'll probably never beat them at this; our design is a big enough departure from the traditional that it's very difficult to make it transparent. We're better off playing to our own strengths, IMO, rather than trying to polish off every single rough edge for ever user, to do something Linux distros with 10x the users and money, already offer, but better.
It's pretty understandable a lot of people would not like this trade off. I, personally, think NixOS is personally the best Linux distribution there is, of course -- but it's understandable why people would not like it, or these design choices. At all. I don't think I waste as much time as you might expect learning about Linux, but I do spend time doing things you probably wouldn't ever enjoy (like fixing upstream packages...)

All of this said, we really should have a graphical installer. I'd love one. :) I'm just saying even if we fixed that, it's probably going to be the least of your issues in the long run, more or less... The installer is the tip of the iceberg.
