Stephen Hawking has demonstrated that he's a good comedian once again.
John Oliver asked many important questions about the Universe, the alien life, the dictatorship by robots, and his abilities to date someone in a parallel universe.
Stephen Hawking could offer deep answers about all these questions.
At least I hope that Hawking has actively participated in this exchange – that it wasn't fully engineered by the writers in HBO that recently aired the interview.
I am actually sure that Stephen Hawking had to actively participate in writing the answers. In particular, his answer about the imaginary time as his most underestimated idea (or a meme he likes to think about) is something that I would fully expect and predict, and something that TV writers, comedians, and other idiots simply could have neither predicted nor fabricated. ;-)
