Re: Racial bias
I think you need to stop thinking about "AI" as some sort of intelligence, and start thinking of it as a type of compiler that compiles training data into a computer program.
So your training data is your computer code, and if your code is racist, your computer program will be racist.
Also, I feel that in many cases, trying to find correlations between input data used is no more scientific than examining a goat's entrails or examining the position of the stars.
