 But artificial intelligence is a really interesting thing. I don't know enough about it, to be honest. I just picked up some interesting quotes. For example, Nick Bilton says, these machines don't have morality, and likely never will. Stephen Hawkins said, it is the biggest invention. It may also be our last. And Elon Musk of Tesla says, artificial intelligence is more dangerous than nuclear power. And I don't mean to scare you with this. I'm all for developing this. But we should look at the ethical issues because the new arms race, as we heard earlier this morning, the new arms race is about data and artificial intelligence. Some people are saying that up to 50% of defense budgets in the near future will be about artificial intelligence and cloud computing, cloud security, digital warfare. So what are the ethics of that? When I drive my self-driving car, will it try to kill me? If somebody had hijacked it? If I connect my toaster to the internet, will it try to suck me in to be toasted? I mean, this is just a potential scenario, right? Big toaster.
