We need to start seeing privacy as a commons - as some kind of a public good that can get depleted as too many people treat it carelessly or abandon it too eagerly. What is privacy for? This question needs an urgent answer.

My fear is that many institutions will eventually alter how they treat people who refuse to self-track. There are all sorts of political and moral implications here, and I'm not sure that we have grappled with any of them.

Surveillance cameras might reduce crime - even though the evidence here is mixed - but no studies show that they result in greater happiness of everyone involved.

Once a term like "open source" entered our vocabulary, one could recast the whole public policy calculus in very different terms, so that instead of discussing the public interest, we are discussing the interests of individual software developers, while claiming that this is a discussion about "innovation" and "progress," not "accountability" or "security."

Simply getting a country's population online is not going to trigger a revolution in critical thinking.

I went to SXSW in 2011. God, that was awful. I mean, I only went because my publisher wanted me to promote the book and the organizers invited me and it seemed silly not to go, especially for a relatively unknown first-time author. This is just not my cup of tea; the fewer such events I do on an annual basis, the happier I feel.

The Internet has made it much more effective and cheaper to spread propaganda.
