"The Cloud" as Hindenburg?

The pithiest single sentence I have heard so far at the Aspen/Atlantic Ideas Festival, underway now (and chronicled in detail by my Atlantic colleagues Conor Friedersdorf and Alexis Madrigal here and here, plus passim by other staff members):

("This is what we used to call 'client - server' in a fancier version and many fewer providers.")

He had a solution to propose too. Context, details, and all of that another time.
