Hm, perhaps I was unclear.

AI absolutely is capable of doing damage, and _is_ currently doing damage. Perpetuating inequality, generating fake news, violation of privacy, questionable IP/rights, etc. These are more pressing than the idea that someday we will give AI the ability to manufacture nano-mosquitos that will poison us all, as Yudkowsky suggested on a recent podcast. He's so busy fantasizing about scifi he's lost touch with the damage it's currently doing.
