Ok, maybe it was Kepler, but the argument still holds: something that we believe is extremely complex could very much become much simpler and obvious in the future. This would require changing the place of the "center". Maybe it mean that money is not what we believe it is, or that banks should not be big companies but some fluid, or that wealth is not really transmitted during a transaction, or whatever. Finance is dangerously complex and may not have to be like that. Every timesomeone explains stock options to me I understand for ten minutes and then forget is definition. This means the model didn't stick, for me at least. (Good mathematical models are very sticky, told once about it one well never forget) So it's a mess and it's worth trying something else.
