Google has been developing smart car prototypes since 2009, completing over 300,000 test miles in California. In 2014, Google revealed its first fully functional prototype. Smart cars are still in the innovation phase of diffusion, and adoption will increase as early adopters and the early majority begin using them. Microsoft released its HoloLens holographic smart glasses in 2016, and with major companies developing these technologies, demand will likely grow as more consumers see their potential. While digital assistants like Siri are not widespread hits yet due to limited functions, customization and diverse options will help make future assistants more relevant to different user groups. New technologies will continue to emerge and develop in the future.
