That's the share of Americans who think artificial intelligence will have a positive effect on the country over the next decade, with more than twice as many expecting negative results, according to a new nationally representative survey of 1,330 adults by the Annenberg Public Policy Center of the University of Pennsylvania. The one bright spot: 57 percent of respondents expect AI to benefit medical research. But nearly two-thirds bipartisan majority say the government has done "too little" to regulate the technology, a finding released six months ahead of midterm elections that will determine control of Congress and statehouses across the country.
