Rights advocates raised alarm, including free speech concerns, after it was reported that the US State Department will use artificial intelligence to revoke visas of foreign students who it perceives as supporters of Hamas, Reuters reports.

The US Constitution’s First Amendment protects freedom of speech and assembly. Free speech advocates like the Foundation for Individual Rights and Expression (FIRE) and pro-Palestinian groups said AI should not be relied upon for assessments related to the decades-old and nuance-filled Israeli-Palestinian conflict.

AI tools “cannot be relied on to parse the nuances of expression about complex and contested matters like the Israeli-Palestinian conflict,” Sarah McLaughlin, a scholar at FIRE, said.
