I found the part related to the social data especially interesting as I had come across very similar content in a book about psychology and statistics. The idea that tweets can be used to predict movie box-office revenue was very interesting as seemingly independent data can be used to make predictions which can result in huge economic benefit. To mention that so much of the work that humans used to do has been replaced by machines and technology is probably stating the obvious, however, this reading made me really realise that so much can be done with the collected and stored data and wonder how much more can be done with the new technology to come.
