As mental health chatbots driven by artificial intelligence proliferate, a small number of states are trying to regulate them. Laws in Illinois, Nevada and Utah are among the first in the nation to put limits on or ban therapy chatbots. But app creators, policymakers and mental health advocates say it is just a start and federal regulation would be ideal. App makers worry the patchwork of laws could stifle innovation needed due to a nationwide shortage of human therapists. They also note that many of the laws don’t cover generic chatbots like ChatGPT.
