To counter the fear of a major disruption, Sam Altman, the chief executive of ChatGPT's OpenAI, told US lawmakers on Tuesday that regulating artificial intelligence was essential after his poem-writing chatbot stunned the world.

The lawmakers stressed their deepest fears of AI's developments, with a leading senator opening the hearing on Capitol Hill with a computer-generated voice -- which sounded remarkably similar to his own -- reading a text written by the bot.

"If you were listening from home, you might have thought that voice was mine and the words from me, but in fact, that voice was not mine," said Senator Richard Blumenthal.
