Continuing
with an earlier post that
Dean Esmay responed to. The topic is can AI empowered machines someday become sentient?
If I am understanding Dean, he is reducing AI to any simulation of human response. In fact he reduces the requirements even further calling any all kinds of everyday uses of technology in appliances and equipment as "low-level intelligence." That is really stretching any definition of AI, and for anything to have intelligence, artificial or real, it has to have some (or if I'm generous at least one) human trait of intelligence.
When my PC-TV card comes on and records a program to DVD it does so without an iota of artificial intelligence. It is simply programed to do so with routines monitoring the clock and starting programs when a time match becomes present. But if we are going to redefine what AI to mean any technological function done for us without intervention I don't know how to respond to such a stretch of the definition.
What if I program a rock to fall from a precarious ledge if it rains. Have it balanced on a lever with a funnel and can next to it to collect water (The water is sensory input). Of course that is grossly simplified from silicon electronics, but I did program the whole setup. Yet if we are going to keep simplifying the definition of AI, then the setup to make the rock fall was done with rudimentary AI too, digitally based or not. In another response Dean said:
To understand this you have to ask what "intelligence" actually means. Which exemplifies the problem I have with redefining and morphing the way AI has been spelled out in the past. You can win any argument with enough definitions.
But this whole discussion is supposed to be about what is needed for a machine to be sentient, not define classes of intelligence. Dean says:
The ability of the human ear to decode sounds and recognize them as words is a form of intelligence. Speech recognition has been an ongoing effort in AI research for decades, and in case you hadn't noticed it's getting scarily good.
Decode and recognition are functions, not intelligence. Depending on what reactions follow and acts on those functions, and how constructs to bring ACTION ensued, it may or may not be a sign of intelligence. A person in a vegetative state may still have the decode and recognition, although not a recognition that triggers awareness to respond with an action. This is like AI with a rudimentary definable intelligence but it will still never be aware no matter how massive you make the program, and therefore not sentient. The same with speech recognition which is another function, one programed to react with a response. In spite of the scary advances today, speech recognition about as emotional and sentient as my rock falling off of the ledge.
The same with face recognition. Terry Schiavo's eyes would follow the doctor, yet they said it was simple reaction. I don't want to get into the pros and cons of that, but we can say emphatically that a robotic machine's recognition is simply a reaction without sentient awareness no matter how well you refine it.
Martin says:
if you can't tell the machine's not sentient, then it's sentient. Sentience is one of those "I'll know it when I see it" phenomena. I don't buy that otherwise just fooling us enough to pass the Turning Test would make the machine sentient, and I don't think you would find too many scientists to agree with that. Other examples like a machine that writes chart busting music, paints classic art or designs beautiful houses is also just a narrow form of passing the Turing Test that comes no where near being sentient.
You give me all of these examples that, I guess, are supposed to be the road to being sentient, a state of conscious awareness. That is just like some in government that think more (or bigger) is better. If we just build enough circuits, memory, communication busses and vast enough programming to simulate every function and cell of the brain, we can do everything. Probably so but we are still left with a non-sentient machine. One that should easily pass the Turing Test, and move with human like motion like Data from Startrek. Yet it is not self aware like our lovable Data.
So please. Will someone tell me where this state of awareness of one's own existence is going to come from? And Dean, engineering ethical constructs into artificial intelligences is a construct of AI that gives the machine no will of its own, at least unless, assuming it could become sentient, then the machine can decide whether or not it wants to abide by those constructs.
I didn't get through all of the responses to Dean that I wanted to make, and is similar to my response on his blog, but I I have a busy day and this will have to be enough for now.
