All these systems stay proprietary, and then others can't build on top of their previous work. Seemingly any "science" which is designed to make money gets locked up in intellectual property or patents and the state of the art never progresses. We have probably re-invented the exact same systems over the last 30 years, poorly, because companies are too bass-ackward to share their engineering work.
