This all really belongs over at Geek speak, but in the meantime -

The net has a memory, viz google or yahoo search

What it doen't have is reasoning - the data is not structured or parsed into any ule based system, and the data representation is in many languages, not in any sommon representation system -

And then, if thee net did have the resources to reason, the reasoning process would still lack goals - the net has no desires -

it is interesting to contemplate on goals for machine reasonin processes -

also to contemplate on machine self awareness -

what fundamental knowledge and goals do you give a machine in this case?

asimove wrote a whole series of books on this, the robot series, but that was for mobile robotic units, and not for static machines that simply communicate with human beings

denial of service attacks have successfully been mounted - I suppose that the URL locators are vulnerable -

My guess is that the next stage will be the need for the search engines to have a review of what's remembered - possibly by machine intelligence - this was tried many years ago simply by counting external links to any site - but that won't work anymore
