The document discusses the history and development of artificial intelligence over several decades. Early research focused on symbolic approaches using rules and logic but progress was slow. More recently, machine learning techniques such as deep learning have seen increasing success by learning from large amounts of data without being explicitly programmed. These new approaches have achieved human-level performance on some tasks but full human-level AI remains an ongoing challenge.
The document discusses the history and development of a new technology called blockchain. Blockchain first emerged with bitcoin, an electronic currency not backed by any government or central authority. It has since expanded and various industries are now exploring blockchain's potential for securely recording transactions and sharing information across networks.
