Imagine for a moment that you went into a coma and woke up 40 years in the future. Of course, there would be certain things that you’d expect to find upon waking. Like, say, jetpacks, flying cars, commercial space travel, a cure for cancer… perhaps even instant noodles which don’t taste like feet. But what you probably wouldn’t consider is how culture might have advanced. Things that are totally unacceptable now, for example, may well be so commonplace in the future as to become utterly mundane. And for people of a certain generation, it’s actually kind of like that now. Because if you measure current trends against the state of play 40 years ago, it becomes obvious just how much the world has changed in a few decades.
