The same happens at the library as I select my books at home and put them on hold, wait for the email, collect them from the hold shelf and self checkout, and return them to a book drop. I do my banking online or at a machine. I do shopping online and wait for things to be delivered and don't even have to sign for them.
My parents' generation when they were old used to make excuses to go to the Bank, the post office, or the library, just to speak to someone and see a friendly face. Getting out of the house to be connected with the real world made them feel alive, but no longer so. I even talk to my doctor by email!
As we age, interaction with other human beings is going to get harder and harder as technology does all the things that friendly people used to do for seniors. For many, Facebook is going to be the most dependable way to have a few friendly comments from someone we know on a daily basis.
It is sad to see that the real world will soon be overtaken by the virtual world and the virtual world will be full of the friendly faces we used to come into contact with everyday.
