Be careful about trying to out maneuver Musk in an interview
The interviewer makes a mistake in letting Musk turn the tables and interview him. He's on the defensive.
He shouldn't be defending his employer. Musk, in the past, has certainly said a bunch of stuff he shouldn't. Here his intellect and speed on his feet are on full display.
I think making Twitter or any social media feed "responsible" is a tall order. He's among the few trying to promote free speech that's neutral (not leaning left or right). I hope, for everyone's sake; he's successful.
