Next week several hundred of the world's leading digital thinkers will converge on the Texan town of Austin for the South by Southwest festival.
They range from the people behind some of the world's most successful computer games and social networks to Craig Venter, the man who mapped the human genome.
Although they are mostly experts in technology and its impact on society, we thought it would be interesting to apply their giant brains to some of the biggest questions of the age.
Like, how can we avoid catastrophic climate change? Or, should we be afraid of China? Or, do newspapers have a future? What questions do you think we should ask them?
Please suggest yours below and we'll put a selection of the best to the uber-geeks. Then look out here for our in-depth coverage of SXSW beginning on 11 March.
