There's no limit to how much a house in San Francisco can cost. There is no limit to how much heart surgery in any hospital can cost. There's no limit to what a four-year college degree can cost; it can potentially cost infinite because the government will just keep subsidizing it ... It's obvious what we need to do. We need to technologically disrupt those sectors. We need to do to the slow sectors what we've done to the fast sectors. We need more technological innovation. If we don't do that, this story evolves in to the exact opposite direction that everybody's worried about, which is what's actually happening right now.
