Planned Obsolescence in Humanity Itself

We, like all organisms, are designed for planned obsolescence. Aging seems built in, no accident of nature, and I suspect it’s not just for population control, but serves the general interests of the perpetual experiment that is evolution. The churn must keep churning. This means more births, and removing earlier variants, in a perennial, persistent way, to produce newer experiments in evolution. DNA seems to be varying itself, yet carrying a message into the future.
