Politico reports that a poll found Americans see a serious risk of AI destroying humanity. A post quoting the report makes a case for AI’s benefits, crediting it with helping paralyzed people speak or walk again, detecting cancers doctors would otherwise have missed, and predicting more than 200 million protein structures. The commenter also claims a custom AI tutor helped students learn twice as much in less time, outperforming an active-learning Harvard physics class.
