There is a book, and sadly I can not recall the author or the title, but the book was written in the early 90s. It was about how computers were going to be the break down of society. How we will all become hermits in our home because we will never have to leave for anything. All of our services will be online, we will be able to order groceries online and have them delivered to our doors, we will be able to work from home. We will never have to leave our homes for anything.
At the time I read this, I thought it was a bit far fetched. I am starting to think this guy was right all along. Everyday it seems you are able to do more and more "errands" without even leaving your home. The idea of this seems kind of odd to me. We need to be more social. So I will keep driving down to my local Publix and buying my groceries there.
