The point is...
Radio will still work long after your internet connection and mobile phone network has gone down. Almost every country in the world which licenses amateur radio operation also has a dedicated network of operators who train and liaise with their local emergency services. In the event of some disaster (tsunami, earthquake etc) when power has been lost or the communications infrastructure damaged or overloaded radio amateurs can still deploy effective communication channels. These channels can be voice (analogue or digital) or digital (packet radio, amtor, psk etc) and can be local, national or international.
Do you realise how much of your "skype" connection uses some form of technology based on or derived from wireless? Maybe a satellite broadband connection or wifi link is used. Designers are needed to develop such technologies and amateur radio has been a good starting point for many such engineers and designers.
Transatlantic aircraft still use shortwave radio for communications and the frequencies they use are subject to varying propagation conditions. A world wide network of radio amateurs, who can devote far more time to propagation studies, still continues to provide valuable information to the professionals.
And, it is a fun hobby to boot.
