After the wars, everyone pretty much putters around nomadically or in scarcely holding together cities until the Vulcans show up - and suddenly they have all this insanely powerful technology and everyone has a purpose in rebuilding their planet and now getting out into the galaxy. It seems logical to me in the context of that history, society would evolve to where most people don't need to screw around on a Facebook during the day because they're stuck in their cubical job that they're only half interest in.
It turned out Douglock was really just Warlock reanimated by the Phalanx back in the '90s with Ramsey's memories. At some point, Douglock was used by the Red Skull for an attack on S.H.I.E.L.D. - with the trauma jarring Warlock to remember who he was. After his brief 1999 solo series, Warlock went back out into space to amend for the actions of his Technarch species. After the events of Annihilation: Conquest, he returned to Earth.
In Magik's case, it's not really Illyana. After Inferno, Belasco bent time / space to resurrect the Darkchylde for his own purposes. Eventually, she ran into the X-Men and has been working with them / causing problems in the last couple years as, well, she's without a soul. With the most recent New Mutants series, she actually managed to secure back a soul. So in a fashion, she is a new "Illyana."
Doug Ramsey is also fully alive again, after being resurrected by Selene for the purposes of killing people during some random storyline.
