look, the more complicated the edge is (ie technically heavy, too dependent on special market conditions) the faster it will wear out.
if the edge is something extremely simple, related to basic supply and demand and your eye is trained to convert chart information into information about what traders are doing and how are they percieving the market, then your so called edge will not wear out (only if traders are replaced by robots or aliens invade wall street)...
