Do we REALLY need a phone?

I disagree with that GSM phone is dying. In Europe almost everyone over 
12 has a GSM phone and use it every day. How can you state it is dying?
On the other hand noone knows what would happen to the Internet if all 
those people would choose to use VOIP instead of PSTN (Public switched 
telephone network). The two networks have completely different 
characteristics and PSTN is better for voice communication.
