The mereological fallacy committed in the very title of the article. Could be a first. Your brain does not learn anything, nor is it capable of learning. Only a (mostly) whole human person (and some higher animals and possibly insects) with a (mostly) functioning nervous system including a brain is capable of learning. A brain also cannot feel fear, in fact it cannot feel anything, nor can it sense anything, nor can it experience emotions, etc., etc. I hate to be so picky about an otherwise admirable post but this is how we end up with concepts like ‘machine learning’. Much like a brain, a machine is not capable of learning anything but for different reasons which I have written about extensively in a ton of other posts on the topic.
