Six months after President Donald Trump warned states not to regulate artificial intelligence, they are increasingly doing just that. States are scrutinizing how chatbots interact with children, how employers use AI and what developers must do to prevent an AI-caused catastrophe. State lawmakers have stepped back from earlier, wider-ranging attempts to regulate AI that were vetoed or otherwise derailed by governors. But they are returning with legislation that is more targeted. The White House doesn’t seem to be making good on its threat to sue over state AI laws or withhold money. Rather, it says it wants to enact its policy framework through Congress. That includes preempting state laws that target AI development, although not laws regulating AI use.
