I'm reluctant to give much credence to Cowen's TCS, given that it woefully underestimates (I would say "ignores") the effect of the internet on well-being. The other points are reasonable though.
Everyone brings up the Internet. But the internet has not changed people's lives as significantly as railroads, telegraphs, plumbing, electricity, radio, automobiles, central heating, air conditioning, telephone, or television did. I don't mean it hasn't changed it as much as those things combined; I mean each one of those had more impact on daily life than did the internet.
