What have I got wrong?

Sci-fi authors often extrapolate current events, inventions, and issues into the future, so they run the risk of getting it wrong. Usually, the farther they extrapolate, the safer the extrapolation, because who knows what things will look like thousands of years hence? Near-future extrapolations can easily be proven wrong later on in the life of a novel. I’m more than a sci-fi author, of course, but I’ve written enough speculative fiction that I’ve guessed a lot about what will occur in humanity...
