The near-future is comprised of three parts: 90% of it is just like the present, 9% is new but foreseeable developments and innovations, and 1% is utterly bizarre and unexpected.
(Oh, and we're living in 2001's near future, just like 2001 was the near future of 1991. It's a recursive function, in other words.)
However, sometimes bits of the present go away. Ask yourself when you last used a slide rule — or a pocket calculator, as opposed to the calculator app on your phone or laptop, let alone trig tables. That's a technological example. Cultural aspects die off over time, as well. And I'm currently pondering what it is that people aren't afraid of any more. Like witchcraft, or imminent thermonuclear annihilation.
Yes, I know witchcraft accusations are a major problem in some parts of the world even today: and there's a 1950s cold war replay between India and Pakistan, with hundreds of H-bombs on each side and a hot line between New Delhi and Islamabad. But witch hunting is passé in New England and Scotland and the Germanies, and nobody really expects Vladimir Putin and Barack Obama to start playing nuclear chicken like it's 1974.
So what happened?
Peel back the obvious explanation ("the cold war ended!") and there's an interesting technological rupture underneath.
