GIGO
What these "AI" things can do is what we should expect based on what they are. Feed them a mountain of stuff produced by humans and they will eventually be able to respond and act much like humans. Feed them biased stuff, and of course they will be biased.
But, is that what we want? Wouldn't we rather have machine intelligence that is factually and scientifically correct? You get that by specific algorithms and carefully selected reference data. Lots of work, but in theory the world only has to do it once.
