one sort or another, there must have been that bias in the process that produced the end result. like i say, different human decisions that went in to the process would produce completely different results. >> tucker: so this gets to the core business at google and the core question about google, which is google search. so all human information essentially flows through this portal. if you ask google and i have, how is it sorted? they will say by an algorithm. and the suggestion is that it's unbiased because a machine is doing it. you are saying that is not true. >> right. in fact, in my experience, as algorithms get more advanced, it means they have more human decisions going into them. so there is actually more opportunities for human beings to influence, you know, the final product. >> tucker: so, this is a meaningful -- this is not an academic conversation.
