2010s: The remaking and erasure of the individual. The individual (sacred in Christianity; one among the undifferentiated masses in Marxism) cut off from past, future, and fellows, has nothing left but an unsatisfied and unsatisfactory self.
The isolated individual rejects the self as having been found in “the wrong body” (transgenderism) or “the wrong species” (variously known as transspeciesism, such that one identifies as an “otherkin” or a “furry,” i.e., as a member of a non-human species). Or the unsatisfactory and unsatisfied self rejects the limitations of body and mind and so advocates for transhumanism, with the individual “augmented” by various technologies in a man/machine hybrid

2020s: Narcissistic cannibalism—the unsatisfactory, unsatisfied yet self-obsessed individual is running out of realities to reject, alter, or destroy. Caught in the grip of enraged and insatiable disappointment, the empty self demands that remaining realities be destroyed more completely, more absolutely. So now we see the narcissist step into a kind of cannibalism. That which is affiliated with the failed human project must be absorbed into the empty and implacable self.
The narcissistic cannibal, caught in an unbearable present, aims his appetitive rage at the past and the future. We see this repudiation of the past in the recent advocacy o
f human composting. The human body and all that it represented may be broken down into its component parts and then absorbed by the hungry living. At the same time, we are being urged to cannibalize our future by reducing our children to the status of sexual consumables by normalizing pedophilia.

The human rejection of God and man, the destruction and even the devouring of the past and future—these lead to the nihilistic dynamic.
