What you are saying is true. The Internet has been around for some time, but for all technologies, there are early adopters and users. At some point, a normal distribution is reached and a large number of people change their behaviour. That said, there are always some people who strongly resist change.
The same applies here. But that is where the trend becomes exponential. It is getting faster and faster. People are encouraged to use the Internet now. Companies are saying they will charge if postal services are used. There is truly a change in behaviour. Above all, the pace is accelerating. What seemed sufficient in order to adapt one year at a time is no longer sufficient. Some parts are still viable with modifications.
I will go back to your comment about cities. In downtown areas, it does not work. Moreover, we know full well that people always resist change. In order to successfully implement change, a lot of communication and information sharing are needed.
