<div class=""><span style="float:none;display:inline!important" class="">Yes, some parts may be simple, and even occupy a large fraction of the brain. Even so other parts may no be, and even if they occupy a small fraction of the brain, it may take a long time
to figure out how to create systems that substitute effectively for them. I discuss this more at: <a href="https://www.overcomingbias.com/2016/03/how-good-99-brains.html" target="_blank" class="">https://www.overcomingbias.com/2016/03/how-good-99-brains.html</a></span></div>

<div class="">### I wholeheartedly agree with the premises you outline in your blog post above but I would disagree with the overall conclusion. </div>

<div class="">Indeed, here we encounter issues related to distinct levels of the organization of matter and information. The lower parts of the brain encode knowledge learned in the course of evolution, stored genetically, they are not malleable in individuals
(i.e. allow only very limited individual learning) and as noted previously, are not very modular. The cortex encodes relatively small amounts of evolutionary knowledge which allows the construction of an individual learning engine that relies on highly modular
structure. ...</div>

<div class="">But, luckily for the AI designer, the genetically complex brain parts are not important for being smart. They are there to integrate information from your gut and tell the gut to move, not to recognize images and perform rocket science. What we
call intelligence resides in the cortex and its interaction with some forebrain ganglia, the genetically simple parts.

What is the evidence that one merely needs to model the cortex well to have a machine that can do most jobs as well or better than humans?</div>
