Here's the actual definition of The Singularity. You'll note there's nothing there about the human brain.

The technological singularity is a hypothetical event in which an upgradable intelligent agent (such as a computer running software-based artificial general intelligence) enters a 'runaway reaction' of self-improvement cycles, with each new and more intelligent generation appearing more and more rapidly, causing an intelligence explosion and resulting in a powerful superintelligence that would, qualitatively, far surpass all human intelligence.

Made more simple, it is the point in which computers begin editing their own software and programming, and writing themselves new software and programming, WITHOUT HUMAN INPUT. This is where theoretically, the RATE of the increase in abilities, becomes exponential.

Right now, only the abilities are increasing exponentially, not the rate of the increase. This is a important distinction.
