With my Google Home, I often ask it, "Can my dog eat X" and it'll answer usually from the single answer from Google. While Google Home usually says the source, "According to WebMD..." or "According to ..." it would be horrible if it gave the wrong answer - saying something was safe to eat but it really wasn't. I hope they take extra precaution with answers related to medicine/safety.
Relevant text: "Google spokeswoman Susan Cadrecha said the company’s goal isn’t to do the thinking for users but “to help you find relevant information quickly and easily.” She added, “We encourage users to understand the full context by clicking through to the source.”" I sincerely hope no one is relying on Google to do the thinking for them.
How is the average, non-technical person supposed to assume that Google won't give an accurate answer to a medical question?
