The author notes that they now use texting, email and instant messaging to communicate with family instead of phone calls. They also rely on their phone's GPS to get directions instead of printed maps.

It suggests interactive touch screens and mobile payment integration could take digital signage further, but that the next major development is difficult to predict. The author remains curious to see what new technologies will transform digital experiences in the coming years.
