Actually I'm a forecaster, which means I'm not a futurist, I do not predict. Predicting assumes a deterministic universe.
Forecasting assumes that the cone of uncertainty is also the cone of possibility.
By thinking logically about likely outcomes, one can influence those outcomes. My job is therefore mapping that uncertainty to help people understand what is possible. Most technologies take 20 years to become an overnight success. In terms of the Internet, we're at the bottom of the S curve. Everything we've seen so far is just the beginning.
