DO machines speak? If so, do they have a constitutional right to free speech?

This may sound like a fanciful question, a matter of philosophy or science fiction. But it’s become a real issue with important consequences.

In today’s world, we have delegated many of our daily decisions to computers. On the drive to work, a GPS device suggests the best route; at your desk, Microsoft Word guesses at your misspellings, and Facebook recommends new friends. In the past few years, the suggestion has been made that when computers make such choices they are “speaking,” and enjoy the protections of the First Amendment.

This is a bad idea that threatens the government’s ability to oversee companies and protect consumers.

The argument that machines speak was first made in the context of Internet search. In 2003, in a civil suit brought by a firm dissatisfied with the ranking of Google’s search results, Google asserted that its search results were constitutionally protected speech. (In an unpublished opinion, the court ruled in Google’s favor.) And this year, facing increasing federal scrutiny, Google commissioned Eugene Volokh, a law professor at the University of California, Los Angeles, to draft a much broader and more elaborate version of the same argument. As Professor Volokh declares in his paper: “Google, Microsoft’s Bing, Yahoo! Search, and other search engines are speakers.”
