DISCOVERY: Human Cloning

What I don't really get is if it would even be possible to clone someone after the embryo has developed. Movies obviously suggest one day we could clone someone in any state of their development (when they're an embryo or when they're 46 years old). But if the latter is true and you cloned someone at a later stage in life, surely it must be infinitely more complex than simply growing them in a petri dish? Wouldn't the clone essentially be a 46 year old baby since I don't imagine it would be possible to clone all the memories and social imprints that the original person experienced (though this is a completely non-informed statement)? I'd assume cloning could/would only occur at the embryonic stage (i.e. immediately following conception), then I don't see how it's all that different than what already occurs today with multiple offspring births resulting from mothers seeing fertility specialists (i.e. Octomom).
