Correction, 8/1/14, 4:22 p.m. EST: An earlier version of this story mischaracterized the type of businesses LegalZoom helped incorporate in California last year. They are LLCs. The story has been updated accordingly. We regret the error.

In June, Robert Weber, the senior vice president and general counsel of International Business Machines Corp., traveled to San Jose to watch a demonstration of the Watson Debater. In contrast to the computer that bested its human competition on “Jeopardy” three years ago, this machine doesn’t just come up with likely answers to questions. It synthesizes information to develop arguments on different sides of an issue. Weber watched Watson debate whether violent video games predispose young males to be more aggressive.
