I disagree, this isn't always true.
Some people's brains improving gave way to the "evil genius". This greatly affected some lives in horrible ways.
Chemistry for instance, almost worthless and very damaging in almost everyway to the human and animal body.
In fact, Im willing to bet that the more people improve in knowing, the worse things will get actually, culminating in torturous things for most people, we never had the heart to go with the mind.
people could turn shoelaces into something bad, and usually do, the dread, deceit, and just plain darkness and negativity will grow to immense levels. For we were only animals the entire time, a mixture of monkey, wolf, and rabbit. We will have to many people as a rabbit, be insane like a monkey, and eat (including eachother) like the wolf in all areas.
Just imagine what a wolf monkey rabbit would do if he had the mind to do it.
