The poles of American politics are coming together over artificial intelligence. Left-wing socialist Bernie Sanders and right-wing strategist Steve Bannon have joined forces to push for more human control over the rapidly-evolving technology.

Sanders, the independent senator from Vermont, and Bannon, a former Trump White House adviser, will both appear at the “Pro-Human Assembly” in Washington, D.C., on Tuesday, alongside a diverse set of speakers, to convince Congress to work faster to curb the impact of AI.

The rare pairing of a progressive leader and a MAGA voice is a sign of how AI is upending political alliances.
