The document discusses the X Internet, which was coined in 2000 and stands for the Executable Internet and Extended Internet. The X Internet allows code to be executed fluently on users' devices, reduces unnecessary data exchanges, and connects physical objects to the internet through technologies like RFID and sensors. Some advantages are that applications take up little data size and processing can occur locally on smart devices. However, issues remain around standards, security, privacy and providing seamless experiences while addressing the web's limitations of bandwidth usage and lack of interactivity with the real world. The document concludes the X Internet shows promise in overcoming such problems.
