Coins and Dollars, Update them? Options

[Paradox of Life]

Should the coins and dollars be changed to more recent presidents? Do you think it's about time to update our currency to the modern times? To represent someone different for a change rather than the same faces that have been on each quarter, dime and nickel? Or should we keep them the same as a representation of the past? What do you think?

[Paradox of Life]

The representations of the present could be representations of the past to the future (that makes sense?). The faces have been the same for a long time and people have taken their messages for granted now. If there was a change, do you think people will respect the new faces? Being the president of an important and difficult position. If you want to honor someone that has worked so hard to keep the country together, what better way to do this than put it on something that someone sees every day? And values? Do you think it's about time we should let some rather ignored presidents get their share of time on the US currency?
Do you even care? o_O;
