In 1900, David Hilbert composed a list of 23 important unsolved problems in mathematics, at the time he commented: “If I were to awaken after having slept for a thousand years, my first question would be: Has the Riemann hypothesis been proven?” (not yet it seems -> http://en.wikipedia.org/wiki/Riemann_hypothesis )
I’d probably ask
“show me your TOE‘s & GUT‘s”
or
“ask what is the population of the earthsolar system?”
or maybe even
“when did machines attain self-awareness?”
what would you ask?
