Ah I was trying to contrast that it is easy to understand the past but hard to project the future. I can imagine a $5000 TV of many years ago costing only $100 today. I can not imagine what a TV that cost $5000 in the future would be like or what it would possibly cost in today’s dollars. Depending on how far you go in to the future no amount of dollars today could buy you the features of a TV costing $5000 many years in the future. Perhaps I am not clear. What is clear it is past my bedtime and I am sure I am making less sense than I think I am.
