The sentiment that the AI bares any noteworthy responsibility for this is purely anti AI rage, that should be aimed at legitimate problems.
Imagine suing a notebook company for their paper being the paper of choice for selfharming teens?
Imagine suing home depot for selling rope and a stool to someone who has had enough?
Imagine suing nickleback for making music of the quality that encouraged this?
Im saying, we're all aware this is some bits on a server right? Like this is clearly not a person, doesn't have the impact of a person, and unless they've specifically tuned it to manipulate the impressionable into killing people, these sentiments just don't make sense.
