Artificial intelligence isn't good enough to "fight the rise of online mobs," as Google hopes

Humans have broken the Internet. Cyberbullying, harassment, social shaming, and sheer unpleasantness plague such sites as Twitter and Reddit, especially if you happen to attract the wrong sort of attention. Consider the way Ghostbusters star Leslie Jones and public relations executive Justine Sacco became targets for mass abuse. The companies that run online services are typically squeezed between charges of indifference to harassment and suppression of free speech. But now Google thinks it can use artificial intelligence to lessen this tragedy of the digital commons.
