I think the moral is that you shouldn't try to write software for which you don't have the hardware to run on, not even if the code could run itself by emulating the hardware. A rock runs on physics, Euclid's rules don't. We have morality to run on our brains, and... isn't FAI about porting it to physics?

So shouldn't we distinguish between the symbols physics::dynamic and human_brain::dynamic? (In a way, me reading the word "dynamic" uses more computing power than running any Java applet could on current computers...)
