This document discusses emerging tech trends for 2018 including facial recognition, virtual and augmented realities, subscription economies, and virtual assistants. Facial recognition is increasingly being used for security purposes but also raises privacy and bias issues. While virtual realities still have limitations, augmented realities are growing through applications in retail, art, and education. The subscription economy model is rapidly expanding and changing how consumers access goods and services. Finally, virtual assistants through voice interfaces are becoming more common in homes and offices through devices like Amazon Alexa and Google Home. The document considers implications of these trends for libraries and ways they could engage new technologies.
