Throughout history, the beliefs and reasonings for existence drove people to do things. Something external. The belief in god and multiple. As this belief eroded, and with the emergence of the internet, smaller subgroups with specific belief systems formed, probably out of the drive for some sense in this world (along with some social-group stuff).
Because there is no actual meaning however, nothing greater humanity can accelerate towards to transcend to, no perfect harmony, consciousness goes against nature, as it can question it, moralize it. I’m neither making a judgment about nature nor consciousness, but nature didn’t intend to be questioned. To provide meaning to beings searching for it in a meaningless world. As nature does, it establishes equilibria and as such, nature, or the nature of consciousness itself, will lead to its own destruction, for it was not meant to stay.
