When I worked at Facebook, I used to give a talk to all the incoming product managers about science fiction. My message was that the role of product managers—and tech companies broadly—isn't to come up with new ideas. The ideas and inspiration needed are readily available in literature.
Instead, as tech practitioners, our role is to consider the technological tools currently at our disposal to determine which of these sci-fi ideas are ready to be built and to build them. The challenge is to have the judgement and sensitivity to determine the next logical step and the drive to make it happen.
