Bill Gates has outlined a series of policy proposals aimed at managing AI’s social impact in a new essay published on Gates Notes. He said the open letter “Pacing the Frontier,” which calls for slowing AI development, merits serious consideration, though he questioned whether such an approach could be maintained over time. Gates proposed a “robot tax,” arguing that the current tax system incentivizes companies to replace human workers with machines and that new taxes could both slow that shift and help fund worker retraining. He also suggested creating “human reserved domains,” where certain tasks would be limited to humans or primarily carried out by them, citing the communication of medical information as one example. Gates said such measures could affect the profitability of AI labs and technology companies, while adding that the detailed rules and job definitions still require further discussion.
