Needless to say a lot of people disagree with that, because of the shootings. And internationally, a lot of societies regulate guns a great deal.
I'm not saying this to steer the conversation towards gun control, or to compare AI use to killing. Rather, I'm saying that the conversation here so far has has been confused because people have different ideas of what "it's just a tool" means, so they're talking at cross purposes.
To some it's an obvious statement of fact; almost everything man-made is a tool, AI is a tool like a pair of shoes or a guitar is a tool.
To others it's a statement that corporations should be held blameless, and access is a moral right that shoudn't be limited on consequentialist grounds.
