It's the passage of quantitative changes into qualitative changes. It's one thing if a single lemonade stand keeps track of its customers. When the same lemonade stand can almost instantly access its customers' complete life history, it's a completely different thing.

I can even put it on your tab, since I know you've never been late with your payments and you pass through here every Saturday" It sure might be convenient, but that doesn't make it less creepy.
