Speaking on the critical issue of declining birth rates, Musk insisted that we should be "very concerned" as these rates are "accelerating in most countries." The implications, according to Musk, are dire.

But it's what he said next that was very telling.

"In the sort of extreme form of the environmentalist movement, people start to view humans as a plague on the surface of the earth, as a fundamentally bad thing, and with the implication that if all humans disappeared, somehow earth would be better off." Musk described this as "The Extinctionist Movement."

He didn't stop there. Musk elaborated on the dangerous ideology, stating, "I think at a fundamental level, you can think of things as a fight between expansionist and extinctionist philosophies. And that's what really matters. If humans go extinct or civilization collapses, whatever policies we may have are irrelevant."

Musk stressed that the survival and expansion of humanity are essential for the continuation of civilization and consciousness. "We must have an expansionist philosophy for civilization and for consciousness. We must seek to go beyond what we've done in the past to increase the number of humans," he asserted. "So, one way or another, this must happen."

"So, the final message is to go forth and procreate?" the host representing Cato Institute asked. Musk replied, laughing and with a smile on his face, "Yes. Go forth and multiply."
