I've seen this interesting article (thanks to the DeusEx Facebook page) about the prediction of the AI surpassing the human intelligence within ~30 years...
2029 is the consistent date I have predicted for when an AI will pass a valid Turing test and therefore achieve human levels of intelligence. I have set the date 2045 for the ‘Singularity’ which is when we will multiply our effective intelligence a billion fold by merging with the intelligence we have created.

Here's the article - it's an interesting read if you like that kind of stuff... 😉
