This document discusses several emerging technologies including Internet of Things (IoT), machine learning, augmented reality, and blockchain. For IoT, examples are given of using sensors to optimize garbage collection and monitor sewer systems. Machine learning involves using algorithms to have computers learn from large amounts of data, with examples like disease research and automated cars. Augmented reality enhances the real world with virtual objects, with potential applications in education, games, and reducing physical space needs. Blockchain is a decentralized network of databases that can enable public, immutable records for uses like payments, identities, and legal contracts. Successful cases include cryptocurrencies and applications where transparency and trust are important.
