I think it's quite likely that within a couple of hundred years there will have been multiple changes that are completely beyond our current compression, that we couldn't even begin to speculate on. Nevertheless, I'll add my speculation to this rather interesting discussion:

The ease and volume of communication is bound to increase. Perhaps we communicate through technological telepathy, with anyone we want to. We share thoughts and senses with groups of people and solve problems by adding more brain power. The Mythical Man Month is no longer mythical. Learning and "news" become instant. Communication is probably faster than the speed of light.

Physical objects are only slightly constrained to their form and location. They can be transformed and moved almost as easily as energy can. Having something only requires thought and currency.
