Influenza isn’t complex, but it uses the insane growth rate of f(x) = x! , one of the fastest-growing functions out there. The greatest benefit of the #flushot isn’t keeping *you* healthy, it’s retarding that combinatorial explosion enough to save lives. Get one.
Is a brain all you need to have a functional mind? Is the body just peripheral to cognition? Many researchers think so, but advocates of embodied cognition have different ideas.
(Quick note: “Altered Carbon” is racy & gory, but also very good. It doesn’t get particularly hung up on the “Is a copy of my mind REALLY MEEEE?!” question, touches on a lot of interesting problems with technological immortality, & actually has a lot of interesting test cases & scenarios for the concept of embodied cognition.)
