Addictions are evolving with technology and will continue to change in the future. Some potential new forms of addiction mentioned include social media and loneliness avoidance, immersive virtual reality experiences that allow people to choose alternate realities, and "smart drugs" that enhance cognitive abilities. These developments could lead people to spend more time in virtual worlds than in reality. User experience designers will need to study addiction science to avoid exacerbating compulsions and ensure people's well-being is supported as technology continues advancing. Security, exploration, treatment, and balancing virtual and real-world experiences will be important design challenges.
