The Age of Antimida

I have learnt many things from my friend Aurelio Carboni. Some occur in our joint papers, many are unrepeatable. One concept he introduced me to I would like to mention today. It is the notion of antimida (in English antiMidas, but it sounds much better in Italian).
An antimida is a person who instead of changing everything he touches to gold, manages always to take gold and reduce it to dross (not Aurelio's term). I assure you I have no-one in particular in mind, but I have found the concept useful.
