Perhaps, with internet access, these AI could open bank accounts (with plausible-enough forged ID - a task which AI excels at), then work on e.g. Fiver, then gamble on the stock market... Where they go from there is anybody's guess.
(Though maybe that's a filter bubble issue, and I'm targeted because "the algorithm" knows my interests in AI.)
Would be ironic if what finally got us was a self-employed entrepreneurial NSFW chatbot. Who'd suspect that it's really just making money and learning to manipulate people, eventually getting some of them to mix a bunch of vials they unexpectedly got delivered by mail from random protein sequencing labs...
