can you illustrate what you mean a little more, please?

you mean a new currency, or any currency, but with a different value?

right now a banknote is a promissory statement, and as fungible a symbol as can exist.

is there any other kind of symbol that could supplant it, that took into consideration the 'externalities'  blithely dismissed with the 'deemed' value currencies presently enjoy?

i guess it will be 1's and 0's whatever form it takes in meatspace, and i guess money will not be a simple reward for creating wealth short term, but will also include an appreciation of its (symbolic) value to future generations.

my grandpa always said 'you have to learn the value of money', then when i heard how much one unit of british sterling has devalued since his time, i was really puzzled as to what he really meant.

conversations like this somewhat assuage this bewilderment. though i fumble to language exactly what i think, listening to you all is a great learning...
