Irrational exuberance?

At a time when the smell of fear is in the air, I wonder whether my current optimistic state could be seen as another kind of irrational exuberance. Never the less I will boldly assert that:
1 The current financial crisis will be shorter lived and have less economic effect than many are currently predicting.
2. We are on the edge of one of the most productive and expansive periods of human development in the whole of our history.
(I’ll leave all the caveats for another time)
