Will the mainframe ever die?

How many IT departments still use servers designed when Lyndon Johnson was President and gasoline cost 30 cents a gallon? More than you might think. Depending on who you ask, there are somewhere between 7,000 and 10,000 mainframes still in operation around the world.
The question is why? Why aren't these cantankerous old beasts as dead as diplodocus and triceratops? Aren't they outrageously expensive? Isn't it much cheaper to run even the biggest applications on Intel or AMD servers with Unix, Linux or Windows Server?
Answering these questions turns out to be not so simple.
