FLARF POETRY:
Humans have already conquered
Humans would almost certainly need to be extinct
A better shot at long-term survival
Earth is a history of extinction
Humans should settle on other planets
In the case of radically transforming technologies
It is hard to cause human extinction
He may be able to stumble on a technological breakthrough
There is only one advanced technological civilization
We are in the process of killing off our only known companions
Urban life has been destroyed globally
The universe may have been governed
