Considering that, when I was growing up, I expected to be living in a post-apocalyptic world of nuclear-bomb craters and anarchy (assuming I lived at all, which didn't seem likely), the future exceeds my expectations.
But even if we discount that particular horror, I think it's mostly better than I expected. Oh sure, there were the tales of flying cars and rocket-belts, but even as a kid I didn't expect most of that super high-tech stuff to come around in my liftime. Teleporters, talking robots and laser guns were things of the far-future, not something I would ever experience.
Mostly, I expected the world to continue more or less the way it had been, with incremental "under-the-hood" advancements; our cars would use less gas (or maybe use hydrogen), we'd swap out nuclear fission for proper fusion, and they'd make it so our record players would never skip and scratch. We might have self-driving cars (but only on highways where they laid down special control tracks) but I'd still be driving to work every day. Constructing a building would still take a lot of brute, manual labor. Food would still come from the supermarket, and oranges would be a special treat that were only really affordable at certain times of the year. But I was fairly certain that my adult life would be pretty recognizable to myself as a child.
And, largely, that has held true, but that's not to say there haven't been welcome changes. I would never have imagined the immense advancements in computing technology: a computer in my pocket that not only lets me talk to people anytime, anywhere, but gives me access to a huge worldwide database of information? 60" television screens so flat that against the walls they almost look like posters? Computers I can talk (and sometimes talk back) and they understand me? The ability to have almost any item shipped to me from anywhere around the world and have it in my hands the next day? All the music and movies and books I could ever want at my fingertips? Fresh blackberries in February? Things like this didn't exceed my expectations; they weren't even on the radar!
Sure, there are some areas we've fallen short, but we're coming close and none of these hopes -like switching to fusion - were really anything that would affect me directly. If there is one major disappointment, it's that we've almost gone backwards in our space exploration; after NASA's heydays in the 60s and 70s, we all expected things to continue apace; 2001 (the movie) didn't seem so far-fetched (well, except for the talking computer, but that was just fun sci-fi). Giant space stations, bases on the moon, manned flights to Mars, Venus and Jupiter; surely all these things would be accomplished by 2020. After all, we got to the moon in 20 years, right? That space would become a nearly forgotten side-show was as inconceivable to me as my owning a handheld computer.
Then again, I can still look up and marvel at a giant airplane that seems to hang by magic in the sky, or take a moment to appreciate that I can make light appear in my house simply by flipping a switch. I already live in a future unimaginable to my ancient forebears, with more power and knowledge at my fingertips than had even their gods. So what if I do not have a robot companion or the ability to visit Alpha Centauri; I'm still living in a high-tech wonderland and it amazes me every day.
(That said, ask me if the political and social advancements of the world today have matched my expectations; you'll get quite a different answer. Our tech is awesome, but I expected better from us as a people).
