For the other perspective see: http://en.wikipedia.org/wiki/Butterfly_effect

Small fluctuations are often rapidly magnified into macroscopic fluctuations.

Computers sometimes contain elements designed to accelerate this process - in the form of entropy generators - which are used to seed random number generators - e.g. see:

I don't think anyone is talking about impossible things becoming possible. The topic is whether considered paths in a decision can be legitimately considered to be possibilities - or whether they are actually impossible.
