The same way you solve "car addiction", you don't. The internet is such a convenient way to get information and media that it outcompeted a lot of other old activities. Sure convenience has issues, like "car addiction" tend to create obesity, since you no longer train the skills dealing with inconvenience, but the convenience itself isn't a problem.

Rather just like we realized people need exercise, you just need to exercise the parts that you no longer need thanks to the internet.

Car addiction is a real problem, though. Pollution (air and noise), lost use of streets by people walking, chatting, cycling, etc. - increased social isolation, increased cost of living, 40,000 dead people a year, far less freedom for people who can't drive (especially kids), land being reallocated to car infrastructure, legal changes preventing the construction of walkable communities in the name of more convenient motoring, etc.

Similarly, the internet has had a lot of externalities we may not have addressed.
