Regulation is justified when its benefits can be shown to outweigh its costs. Of course, cost-benefit appraisals are imperfect and error-prone. In a famous 1969 article, the renowned economist Harold Demsetz warned against comparing an idealized version of a regulatory proposal (assuming it will work perfectly) to the actual outcomes of the current unregulated system.

The history of harmful regulatory imperfections underscores the wisdom of Demsetz’s warning. U.S. adoption of AI regulation would in all likelihood slow the rate of innovation in technology systems that appear poised to confer enormous benefits on society. Even small reductions in the AI growth rate can lead to huge long-term social welfare losses. Imagine what innovation-driven benefits might have been lost had the government decided to essentially control the internet 30 years ago.

What about AI-related harm? That is highly speculative at this point. Moreover, the federal government is closely monitoring the AI sector, ready to apply existing targeted legal sanctions at the first sign of a problem.

In sum, the AI landscape today features rapidly growing benefits and uncertain costs that, in all likelihood, can be well addressed under existing law if problems arise.

The time may (or may not) come when serious new and unanticipated AI-related problems arise that can best be handled through targeted regulatory solutions. But as of now, the case to regulate AI today has not been made.
