Nobody will even think about it as addictive, because it's going to be an essential part of everyones lives.

Stuff like neuralink or that laser able to send images directly to our retina, will make screens obsolete.
We'll probably replace keyboards with hand gestures, which will contribute to fitness and posture as well.
