I was tempted to call this Philosophy for Our Time – but her title is more appropriate.
She is writing about Data in the Computer Age. That is obsessed by a complex of Big Data, Machine Learning, Artificial Intelligence – and a few other things. All related to the Computer, that has reshaped our society.
If you want a summary in a few words, this will do:
When we let data systems learn from the public at large, and when we allow feedback loops without thinking through the bias that emerges as a result, we allow data to be prejudicially shaped.
She is talking to a huge blind spot in American culture. That has been trained to not see the most important forces in their world.
This one of the things all Americans should read – but most will not. She wants to make American better – but most Americans are not interested.
