Why not try Longbets. From Steve Levitt:
Other bets at the site:
At least one human alive in the year 2000 will still be alive in 2150. (68% agree)
The universe will eventually stop expanding. (only 35% agree).
Some bets that have been offered, but so far have no takers:
By the year 2150, over 50% of schools in the USA or Western Europe will require classes in defending against robot attacks.
By the year 2020, the tickets to space travel - at the least to Moon, will be available over the counter.
By 2030 all surgical anesthesia will be administered and monitored by computers, with no need for professional medical supervision beyond the surgeon.
