Jon Stewart's reaction to Jacob Coxon's description of AI utopia

Ezra Klein says the most revealing part of Jon Stewart's conversation with Jacob Coxon was Coxon's description of AI utopia and Stewart's incredulous response, rather than Coxon's warning about AI doom. Klein says his essay also discusses Francis Fukuyama's 'Last Man' and AI easily solving problems that had bedeviled his father's field of mathematics for decades.
