Rapid advances in artificial intelligence are boosting online disinformation and enabling governments to increase censorship and surveillance in a growing threat to human rights, a U.S. nonprofit said in a report published Wednesday.

Global internet freedom declined for the 13th consecutive year, with China, Myanmar and Iran having the worst conditions of the 70 countries surveyed by the Freedom on the Net report, which highlighted the risks posed by easy access to generative AI technology.

AI allows governments to "enhance and refine online censorship" and amplify digital repression, making surveillance, and the creation and spread of disinformation faster, cheaper, and more effective, said the annual report by Freedom House.
