Rage against the machines: is AI-powered government worth it?

What machine learning and AI, in general, excel at (unlike human beings) is analysing millions of data points in real time to identify trends and, based on that, offering up "if this, then that" type conclusions. The inherent problem with that is it carries with it a self-reinforcing bias, because it assumes that what happened in the past will be repeated. Let's take the example of crime data. Black and minority neighborhoods with lower incomes are far more likely to be blighted with crime and anti-social behaviour than prosperous white ones. If you then use algorithms to shape laws, what will inevitably happen is that such neighbourhoods will be singled out for intensive police patrols, thereby increasing the odds of stand-offs and arrests.
