AI could kill a billion people, Bill Gates warns

Bill Gates has warned that artificial intelligence could cause a billion deaths if misused by people with ill intent, calling it a weapon more powerful than any previously seen. Speaking to NBC News, the Microsoft co-founder urged politicians and law enforcement to establish safeguards and monitoring for the fast-moving technology, though he acknowledged this would add overhead for the industry without dramatically slowing progress. Gates joins tech leaders Sam Altman and Elon Musk in calling for caution, while skeptics like President Donald Trump dismiss such warnings as a hoax and others argue dystopian fears distract from current issues like autonomous weapons.
