Fifty years ago, the way that we consumed food was revolutionized. We began eating processed foods, and it seemed amazing. And then we woke up many decades later, and we realized that food was engineered to make us fat. And I think that such companies as Google, Facebook, Amazon, Apple are doing the same thing with the stuff that we ingest through our brains. They're attempting to addict us, and they're addicting us on the basis of data.
