Reading over the comments up to this point, this is a definition debate, not an intelligent conversation. By some useful readings of the word "singularity", they are indeed relative and there are several in our past, and quite likely several in our future. Looking back at the prognostications in 1980 one can fruitfully argue that we've been through one just since then. By other useful readings of the word "singularity", it lies solely in the future if it exists or can exist at all.

Arguing which definition is "true" is wrong; definitions can't really true or false, they are simply useful or not useful, nor do they have any direct impact on reality.
