Anyone who grew up reading sf, seeing all the usual movies and TV shows, and maybe reading serious stuff like Arthur C Clarke’s Profiles of the Future, will more than likely have developed certain expectations about future technology. Like this guy:
Assuming you’ve clicked through to see the whole thing in its native environment, you’ll have seen that he’s soon put right on that…
But, as often happens with xkcd, it does raise some interesting thoughts – most predictions of the future tend to assume that it’ll be like now, only more so. This isn’t surprising, because predicting technological and social changes is pretty much a matter of guesswork.
But here we are, living in the future as Wil Wheaton likes to say, and we got most of it wrong.
 I’ve still got that somewhere. I think. Possibly in a box.
 Or already seen it anyway
 Like the alleged nineteenth century projection that if London traffic continued to increase, then by the mid-twentieth century, the city would be knee-deep in horse manure. This was a perfectly reasonable prediction based on known technology.
 I haven’t looked it up, so it may be one of those things that gets repeated a lot, but doesn’t have a genuine source
 Or thereabouts
 Not to be confused with Evil Wil Wheaton, who appears on Big Bang Theory. He mostly likes to say things that make Sheldon cry.
