Google's direct answer system is riddled with errors. It's a disaster on mobile devices and will be an even bigger problem for Google Home. Search Engine Land has a good piece on the many flaws of Google's direct answers, or featured snippets as they're also called.
If you're looking for information about Proposition 63 in California, you'll get a featured snippet from a biased source - something that completely misrepresents the issue. Ask Google who the "King of the United States" is, and they'll tell you it's Barack Obama. Ask them about creationism and Google's direct answers will tell you that dinosaurs are made up propaganda designed to indoctrinate our children. It's getting ridiculous.
As Danny Sullivan writes, "These types of mistakes are embarrassing in web search results. They're going to be even worse with Google Home, where Google wills tart reading aloud some of these crazy answers without at least the back-up of other search results."
Perhaps, in this case, Google should fix what they have before they try to create the future.
