We're already letting them bro. The great filter is us. I'll be surprised if we make it to 2050. The entire industrial revolution is an unplanned terraform, and our response to the potential destruction of a stable climate, and most macroscopic life on Earth, is to double down, consume product, elect pedophiles, worship the most morally bankrupt psychopaths and sociopaths in politics, business, and entertainment; not to mention the widespread contempt and lack of empathy for "others" not like me, for some flagrantly dissonant reason.

We are in the midst of a global mental illness epidemic, and the average talking chimp is sleepwalking through it; barely cognizant of what is even happening outside their personalized propaganda bubble.
