Will the Mind Figure Out How the Brain Works?
In an opt-ed piece on TIME.com notable scholar of language and philosophy of mind Steven Pinker is presenting his view on the question if the brain can understand itself:
Will neurologists scan our brains down to the last synapse and duplicate the wiring in a silicon chip, giving our minds eternal life?
Personally I do not feel that 100% understanding is required actually. We do not fully understand the universe but never the less come up with all kinds of useful gadgets that fulfill their intended functions within the margin of error between the applied theories used in their design and actual reality.
As long as we understand the brain well enough to improve it even just a little we will have a runaway intelligence explosion aka technological singularity.
