The next step is obviously for machine to go search for their data themselves. You could have an app in smartphones that would detect criminal activity, so they could collect global data on actual criminal activity (bias: by people having smartphones with them). So you'd need to have little autonomous robots following and watching every human being, and detecting automatically criminal activity, and then they could share their data and now machines could learn unbiased.
