Entrepreneur Elon Musk sipped whiskey and puffed a little weed while musing at length late Thursday about artificial intelligence, colonising space, and the need to give love a chance.

Musk shared thoughts on those topics and more during a podcast with comedian Joe Rogan that lasted more than two hours. At one point, Musk described the constant barrage of ideas in his mind as being "like a never ending explosion," wondering as a young boy whether he might be insane because it didn't seem to be happening to other people.
