In the absolutely epic space opera "Hyperion" (and its sequel "Endymion") the author Dan Simmons theorizes -- through the plot, not through a monologue! -- that AI creatures would offer us tech that we could never invent -- impossibly minituarized personal computers (the size of a discrete and thin silver bracelet, an earring or even smaller implants under the skin, and which are basic AI by themselves), and real-time worm-holes through which humanity finally achieves inter-stellar civilization status.
However, the author is very realistic (pessimistic?) about such an AI community -- actually there's billions of them living in a place humanity can't ever reach or even guess where it is, with internal politics as foreign for the people as our societal dynamics are a mystery to the bacteria around us. Anyhow -- the tech they give to humanity is heavily backdoored and this becomes very apparent and dangerous as the plot progresses.
I'd recommend those books to anybody with a heart and some curiosity about a seemingly optimistic future (which is actually pretty dark).
Be warned though: if you decide to read them, the first ~120 pages of the first book are DARK AND HEAVY. However, enduring it was the best sacrifice of several hours of patience I've ever done in my life. I just couldn't stop reading before I finished all 4 books.
