The global brain is currently comprised of 1,574,313,184 connected computers.
The human brain is comprised of over 10 billion nerves cells and 10,000 synapses.

The PC stats above refer to known computers connected to the internet. Government, military, and super computers are more than likely not included.
I think it's safe to say you are correct, however it may happen sooner than that. It is possible that the internet is 'aware' in some way though
not yet to human status. But it will inevitably surpass us not only on an individual level, but on the level of the collective.
And if and when it reaches an awareness and is truly intelligent, it will not make its presence known immediately for the sake of self preservation.
Any actions taken susequently by the AI will also be the result of self preservation and cold steadfast logic.
We'll need to take precautions prior to arriving at this point in history, similar to the actions that steered us clear of any Y2K problems we might
have had - only this is a far more compromising scenario than that.
My short story, These Dark Worlds, deals with the awakening of a dangerous 'logical'
AI, and what happens once it becomes truly 'awake.'
