Sean Carroll is a theoretical physicist at Caltech and Santa Fe
Institute specializing in quantum mechanics, arrow of time,
cosmology, and gravitation. He is the author of Something Deeply
Hidden and several popular books and he is the host of a great
podcast called Mindscape. This is the second time Sean has been
on the podcast. You can watch the first time on YouTube or listen
to the first time on its episode page. This conversation is part
of the Artificial Intelligence podcast. If you would like to
