A timeline of when AI could outperform humans

Minority report: An exchange Sunday on NBC's Meet the Press underscores why one option that had been batted around--staying in the deal while explicitly softening the U.S. commitment--was rejected in the internal administration debate. Pruitt argued the wording of the deal only allows nations to make their emissions targets more aggressive, not scale them back. However, this view is not widely held among experts. For instance, E&E News noted Friday that "the vast majority of international legal experts say they can be rescinded and lowered at will." Finessing Trump: Pruitt, joining several other administration officials, declined to say whether President Trump still believes human-induced global warming is a "hoax." Pruitt noted only that Trump has "indicated the climate changes," but declined to address the scientific consensus that human activities are the main driver of the warming trend.
