I'm wondering how many of these, if any, happened.

Earth-like planets will be discovered 101/17%

earth-like planets 2010 Though, ultimately, it matters what your definition of "earth-like" is. This get a maybe then?

The Higgs boson will be detected 100/17%

Not in 2010. Though, perhaps in 2012.

The Turing test will be passed 26/4%

Also not in 2010. Though that may have been due to people waiting for 2014.

Perl 6 will climb the charts 135/22%

Something else 106/18%

Seems undefined. So, i'll just respond with a NULL.

Something wonderful 133/22%
