"a brain was always going to do what it was caused to do by current, local, mechanical circumstances. we are descended from robots, and composed of robots, and all the intentionality we enjoy is derived from the more fundamental intentionality of these billions of crude intentional systems."

This sentence is clearly from someone similar to Stephen Hawking. The problem is that we differ from machines exactly in the intentions and capacity to perceive reality. For example, we can never make a machine judge a painting by beauty criteria, simply because beauty is part of the reality, and machines can not perceive it.

All machines can do is "mathematical" and mechanical, we can make them move and act, but we must make foreseeing what is going to happen. For example, an AI response must foresee what questions it might be asked: for it to answer "my name is Bob", we must insert it as a response to the question "what is your name?", "what are you called?", and so on. Machines can not react as precisely as a human being because they do not perceive reality.

Intelligence is the capacity humans have to perceive reality, this is known since before Christ by the Greek philosophers. We simply can not pass it to machines, but we can, of course, imitate it a little and simulate, as we did with AI's.

sir frederic attributed inaccuracies to schemas. memory reconstruction is one part actual events and one part personal schema, which can result in inaccuracies when memories are reconstructed.
