Warren Buffett to George Will- "You are a dumbass"

Ok, that isn't actually what he said, but it is fun to imagine that it is.  Here he eventually points to the competitive advantage of the railroads to trucking.  And Will is mainly attacking passenger rail.  But Buffett mentions Berkshire's $34 billion investment in BNSF, and how good the railroad business is for both the owners and society.  Not too bad for "a technology that was the future two centuries ago."
