Or perhaps the brain works nothing like a CPU.
(The very idea that it does is actually laughable, akin to medieval fantasists imagining that flying machines must have huge white wings with fleshy feathers.)
- aavaas 8y agoYes, a brain does not work like a CPU. As noted by another user in this thread, understanding brain is a considerably harder problem. "CPUs are deliberately engineered so that their different functions are nicely decoupled and easy to reason about but brains are the result of a very messy evolutionary process" -SilasX
- amelius 8y agoEngineers are also the result of a very messy evolutionary process ;)
- Sharlin 8y agoBeing the result of a messy evolutionary process doesn't give you any special insight into other messy evolutionary processes.
- makomk 8y agoI think it's partly the regular, simple, easy to understand structure that makes the approach outlined in this paper fail so badly. Because CPUs are made up of a number of simple, regular pieces connected in a way that's generic and easy to reason about, each of which is general enough to be used across many kinds of programs, knocking out individual transistors and observing the effects on the output of complex programs doesn't tell you much. Which parts of the CPU are used for a particular "behaviour" depends on the whims of the programmer and the compiler's optimisation passes as much as anything else.
- adrianN 8y agoI don't think that "maybe we could understand the brain if we had a very detailed picture" is the same as "the brain works like a CPU".
- ajuc 8y agoNobody is claiming it does.
