我覺得駭客任務其實根本不是講什麼桶中腦或是人工智慧的電影
它其實是在把金融制度運作的原理透過電影隱喻性的透漏出來
因為我近期在金融研究有一些的收穫和理解
我益發覺得駭客任務就是在講金融的運作道理
比方說
我最近在研究週期對數加速定理
它就有提到
肇因於金融泡泡衍生出來的超額報酬率一定會跟一個叫做風險率(Hazard rate)
有個互相抵銷的關係
抵銷的背後原因在於必須滿足
no abritadge condiftion 或是 no free lunch principle
也就是公正的賭局期望值一定是零的這件事情
當金融泡泡越長越大, 風險率會伴隨增大
就跟駭客任務的Neo 一樣,當它後期開始可以飛天遁地之後。
Agent smith也同時變得越來越強大。
這個兩者一起變強互相制衡的概念 就是
超額報酬率(Neo)和風險率(Smith)間的那互相制衡的關係
當Smith最後強大到要毀滅母體和一切時
Neo只能跟Smith同歸於盡了
以下節錄電影我覺得很精彩的一些對話
ORACLE: Everything that has a beginning has an end. I see the end coming. I
see the darkness spreading. I see death. And you are all the stands in his
way."
NEO: Smith?
ORACLE: Very soon, he is going to have the power to destroy this world, but I
believe he won't stop there. He can't. He won't stop until there's nothing
left at all.
NEO: What is he?
ORACLE: He is you, your opposite, your negative, the result of the equation
trying to balance itself out.
NEO: And if I can't stop him?
ORACLE: One way or another, Neo, this war is going to end.
Oracle講的那個Equation我剛好最近有推導到:
基本上就是一個隨機微分方程 有對應超額報酬和風險率的項在裡面

而要滿足鞅定理(Martingale hypothsis)
風險率和超額報酬率一定要互相抵消
這個互相抵消的過程就是Oracle講的Inevietablity (不可避免性或是宿命論)
有人曾經這樣解讀過駭客任務的嗎?
能否討論一下?
