At some point in time in the recent past, a lone bored programmer develops a way to make viable artificial intelligence modeled after the human brain. Rather than sharing their result with the scientific community, however, the programmer proceeds to create an actual AI, giving the AI access to their personal computer and the Internet. Over the next few years, these AIs replicate and spread over the Internet unnoticed, paying for CPU cycles with bitcoins and other cryptocurrencies and sometimes joining science and tech-related online forums anonymously.
One day, someone notices a discrepancy between the percentage of science and tech-related forum users who declare addresses and the percentage of other forum users who do. Instead of dismissing it as some psychological quirk of forum users' personality, or an artifact of existing online forum software, they investigate further and eventually discover the truth. Seeing an opportunity, they break the story to a major news outlet.
The question is: how does society react to the revelation? Do people find a way to live peacefully with AI, or is there a massive anti-AI crusade? Or something else?
EDIT: It appears as if massive clarifications are necessary, so here they are: The AIs do not have "objectives" like traditional AIs; they are based on the human brain and act basically like humans that have an entirely virtual existence. (The question of whether they are sentient just like humans is up for debate.) Since humans don't exactly have predetermined "objectives", neither do the AIs.
"How does society react" is intended to be constrained to what is the future of AI-human relations. Of course, interesting unanticipated consequences outside of this constraint will certainly be welcome; it is just that they are not the primary goal of this question.
