Are they irreplaceable? For myself yes. I mainly play retro games, and to me there is nothing more beautiful than a pixel, I started with an Atari 2600 and when 8bits/16bits came I was amazed. This is very personal and probably for a nostalgia factor, I also live in the 70's-80's span for music and movies.
But I must admit those sonic and doom comparison pictures above are revealing of things I might be missing.
For the new folks, yeah just give them 3D graphs, they will not regret, it is the new thing and they have the right to be amazed with new tech. They will get nostalgia later in their lives, and when techs like volumetric 3D or headsets become mainstream, they will probably regret their HD ready monitors.
