When I see things like the RAND 'long-range forecasting' study, I always look to see if they specify ubiquity -- it's very different to assert that we'll have ultrasonic implants for the blind in a laboratory setting vs. being commonplace and woven into the fabric of society. As William Gibson is fond of saying, "the future is already here — it's just not very evenly distributed." Predicting what will become integral to our daily life is much more interesting/difficult than determining how long it would take to develop a specific technology's proof-of-concept.
