[from in the article in Phil's link]:

'The archaeologist Jacquetta Hawkes once said that every age gets the Stonehenge it deserves,' added Miles. 'For example, in the 1960s, at the dawn of the computing era, researchers argued that you could use Stonehenge as a giant calculating machine.' Later, in the more mystical New Age, it was argued that the monument was really a spaceport for aliens, while, in the Middle Ages, it was said Stonehenge was built by giants. 'By those standards, this latest idea seems to say something quite odd about the twentyfirst century.'

Odd, maybe... unexpected, no.
