Actually Orwell has been dead since 1950, but we need him back. In Orwell's time Communism was a virulent ideology spreading world wide and fast. Communism was so compelling as to cause people to risk their lives spying for the Soviet Union. The Rosenbergs were caught passing secrets of the Manhattan project to the Soviets and were executed for it.
Orwell's Animal Farm and 1984 did more to kill off Communism as any other event during the Cold War. The two novels spelled out the evil at the heart of communism in simple terms clear to the average reader. Anyone who read either book could never be a true believer in Communism ever again.
Today we are afflicted with two dangerous ideologies. Communism, which I had thought really dead since 1989, is making a come back in the US. The Bern is preaching communism. He calls it "democratic socialism" but it's Communism. And ISIS and company is preaching a horrible fanaticism that leads people to massacre innocent bystanders, Christians, Kurds, Yazidi's, anyone not a Shia Muslim.
We need another Orwell to point out the evil at the heart of both these dangerous and horrible ideologies.
