I mean obviously this is very complicated and we still know very little of the brain.&lt;p&gt;Just one example (from what I understand) you can&amp;#x27;t really separate intelligence from emotions. There are researchers in emotions that explain our whole system of affect&amp;#x2F;feeling&amp;#x2F;emotion&amp;#x2F;mood&amp;#x2F;etc. as a very effective abstraction of all the inputs from our whole body (both direct inputs, cognitive processes and stored data). So without a working system of emotions I don&amp;#x27;t think you will have a working brain at all.</text></comment>
