Homo Sapiens Improbis - The Cosmic Web Series, #1

An alien, digitally uploaded to a lurker probe and tasked with observing the Earth is supposed to briefly wake from his slumber every 11000 years and send a report. When he starts noticing humanity's accelerated technological progress and having become a big fan of humanity, he becomes disobedient and starts waking more frequently: every 100 years. There is good reason. His race knows that in sexually reproducing, DNA based life forms, psychopathy is, more often than not, the consequence of the emergence of intelligence.
He knows that when he sends his next report, exposing yet another carcinogenic space faring species, Earth will simply be destroyed. When an average human male with too much time to think, figures out the problem, he decides to provide the man with a tool that can save humanity.
