I loved these quotes from Robert Cringely's 27 September 2001 column on pbs.org:
Though many of his [J.P. Morgan's] tactics [in the early 1900's] would be illegal today, they weren't at the time he used them, and they built much of the world that we know today. Americans do things like that. They build slap-dash empires, then consolidate them by outlawing both the slap and the dash, closing the door behind them.
[Technological] revolutions are rarely fair, often unpredictable, but usually irresistible. The rise of electric money is no exception.
