We've been conditioning people to trust the output of search engines for years and now suddenly we are telling them that it was all fun and games. This is highly irresponsible.
I don't agree. The output of a search engine has been a list of links for years. We check the accuracy of the content of the linked results and we might not like any of them, and change the query.
The problem is when we use voice or an equivalent text as the result. Because the output channel has a much lower bandwidth we get only one answer and we tend to accept that as true. It's costlier to get more answers and we don't have alternatives in the output, as in the first three results of an old standard search engine.
