ELON Musk knocked Rishi Sunak for six last night - saying people will have AI mates but wont need jobs.
And the PM laughed awkwardly as the tech tycoon said robots should be safe so long as they have “an off switch”.
The Space X billionaire warned: “What if one day they get a software update and suddenly they’re not so friendly after all."
They had a nerdy fireside chat following the world’s first AI summit in Milton Keynes.
Musk told the PM that AI has the potential to be a "great friend" that will know you better than yourself.

He said one of his sons struggles making pals adding: “An AI friend would be good for him.”
Musk also said a humanoid robot be able to "basically chase you anywhere" adding an off switch was vital to prevent stalking AIs.
The 52-year-old Tesla mastermind stressed: "It's something we should be quite concerned about.
"If a robot can follow you anywhere, what if they get a software update one day, and they're not so friendly any more?"
Mr Sunak later pressed the Twitter mogul on the perils of people losing jobs to AI.
Softly-spoken Musk said: “I think we are seeing the most disruptive force in history here.
“There will come a time when no job is needed.
“You can have a job if you want a job, for personal satisfaction, but the AI can do everything.”
He added a future “challenge” would be trying to find “meaning in life”.
Mr Sunak beamed as Musk hailed London as second only to San Francisco for AI development.
