Its going to be like ten years before they make a computer that's smarter then humans. Then like 20 or 15 years (I believe) untill everyone ahs a computer that's smarter then humans. Yay.
Then another 30-50 before we could create a self aware AI prototype that can speak perfect english and likes pandas.
Awesome...even more rampant speculation based upon anecdotal evidence and subconscious fear.
I don't think it will be that difficult to create A.I. It will simply take a few small steps then
BAM! an explosion AKA singularity.
We humans have a knack for overestimating the complexity of our minds. All our skills, beliefs and idiosyncrasies are merely byproducts of simple motives and a few genetic subroutines. The key to A.I. lies in recreating a human baby, or in different terms: create a machine with only the attributes a child has with slight alterations to fit synthetic needs over biological needs. Then dynamic, value-based, causal memory handles learning and development. Then the A.I. can be raised like any other child to learn languages, skills and morals.
