People before Facebook found themselves in exactly the same situation as you and managed to survive.

People have become dependant on the convenience of these tools and become, for lack of a gentler word, lazy. Moreover we have this current sense of entitlement -- that all of these details of modern living should be done for us. Having our social circles organized and maintained for us, having infinite entertainment a button press away, food delivered to our door on a whim, cars to take us anywhere always minutes away.

People survived just fine before these conveniences, it just too a bit more effort. You could collect your friends contact information, keep an address book, call them up from time to time. It's not perfect, but it works and starts to break the silicon valley tech giant dependence.

Personally I find adding friction to these processes has actual value. When you slow down and have to put a bit more effort in, it helps you to evaluate what is important, and what truly matters. You prioritize, you make tradoffs. The process IS the richness in life. We all don't need to be jet setting globetrotters to whom paris might as well be New York or london or munich, while robots manage our social lives. There is no substitute for actively working to build a community where you are. You have to put the effort in, and in a single generation we have lost so much of it. But we can get back there again if we try.
