The term AI is fairly imprecise, and might include game playing AIs like Deep Blue and Alpha Go, or research focused systems like Fermi Net and Alpha Fold. I don't think those applications are in need of regulation. What really needs to be regulated is:

1) Mass tracking and collection of personal data.

2) AI being used to make important decisions that affect people's lives.

3) Autonomous weapons. (This is a subcategory of 2, technically, but has its own unique set of problems.)
