That is exactly my point xris , if we could find the illusive butterfly we could turn it into a deadly weapon, let it flap in a precise calculated location and just sit back and wait for the chaos effect to destroy our enemies

Neither am i an expert, but thats the whole idea, as you said; its never about logic and certainty.Its pure probability/unpredictability.
Probably thats why Feyman said no one can understand it since the whole concept of quantum m is about not understanding the movement of atomic level particles as according to the conventional set of laws.

Ah but i disagree, i think certain events can cause greater events but a butterfly has only the power to make us wonder why she was made so beautiful, for us to admire.She is not made to create even a chill breeze let alone a storm.
