I expect money to evolve.

Right now it is a sorta measure for work and materials applied.

I expect new forms of money to be a measure of good will, patience (or waiting / time value), etc.
In fact, you could say that people's seller rating in ebay / amazonia is a form of "money".

So, i believe, in the future, we will see these things expressed as easily as we express money in a bank account today.
