This goes to the chaotic problem which is still to be decided. There is no consensus position on what facts are, what is safe and what is misinformation. Part of the success of modern democracy hinges on being able to switch the leadership out with people who have a different frame on life than the old group. Yesterday's misinformation can become tomorrows facts (consider, famously, the impact Snowden had on the conversation).
Can a company as large as Google do this without splitting their own market along various political boundaries? Will they be forced to take religious, political and moral positions? Will they be out-competed by more neutral or more partisan chatbots? If chatbots become a big deal, will the target audience scale like search did or is it fundamentally fragmented?
