the great majority of money in the US economy today (no matter how you count it) exists as data in computer databases, without any kind of physical support whatsoever - not even paper. It seems that we are heading towards an economy based on digital money. Already in other countries, there are many businesses that don't even accept paper money any more, and take only cards.

So the question is : Do you believe this development to be a good thing or a bad thing? Name at least one potential advantage and one potential disadvantage that you can think of.
