how does visionary feel?

Actually I was starting to think "visionary" goes very much in the right direction myself, FB.

Maybe we'd contrast visionaries (dynamic/dramatic/non-linear predictions) with futurologists (linear predictions)?

What would be the opposite of "linear"? Perhaps this could be tied in with Chaos Theory, where you get past a certain quantitative value and there is a qualitative change, i.e. it's more like changing over to a different graph/formula than following the same formula.

(At this rate I'll get a chance to incorporate all of my interests in this thread )
