First, thank you, everyone, for the feedback. There are some wonderful stories that I recognize and others that I look forward to reading.
Second, because the solicited essays and fiction will only be a small part of the course, I will have to rely on short stories (including novellas) instead of entire novels. That is part of what makes it hard to research. It's much easier to find out about novels, which have more readers and are better publicized than short stories, especially recent ones that have not yet been widely reprinted.
Third, to those of you who think I am being too lazy to do my research myself, gathering information is part of the research process, and I'd be remiss in not making use of the hive mind if it has useful information that I might not. I would much rather be called a negligent teacher than to be one. Academics study one another's reading lists and syllabi all the time. Believe me, plenty of work remains in deciding what material to include, how present it, etc.
Fourth, thank you for letting me know the history of the word "futurism". The sense I used it ("concern with events and trends of the future or which anticipate the future") is the first one in some dictionaries and is widely used at kurzweilai.net, The Foresight Institute, and other sites I have used, but I will certainly let my students know that some people prefer the word "futurology". For those who are interested, here's a Google n-gram view of "futurism", "futurist", and "futurology".
Fifth, some commenters suggested using primary sources and biography. Agreed. I was already planning to include Turing's Computing Machinery and Intelligence, Vannevar Bush's As We May Think, and the stories of Khan Academy, Iqbal Quadir, Sugata Mitra, and others.
Sixth, it was also suggested that I look at past predictions of the future. Also agreed. I assembled such a reading list for a previous course. It hadn't occurred to me to include in my question what I didn't need, because I'd already assembled it, but I see now that it would be helpful.
Thank you again for the suggestions and even for the criticisms. Soliciting opinions from Slashdot is always a story in itself.
