You aren't wrong, but that's presumptive on humans being able to create algorithms that aren't implicitly bias. 2, hopefully not overly simplistic examples, A) Automatic Paper Towel dispensers that don't work nearly as well with people with dark skin. (Unintentional bias on the hands of the designers) B) People getting google banned and then being totally helpless and useless and not being able to get themselves unbanned (an algorithm determined there was abuse, and there is no recourse to tell the machine that it was mistaken, the entire thing was automated away via algorithms.)
