Can technology replace human intelligence?

This week in my Bioelectricity class we learned about extracellular fields. One facet of the study of extracellular field I find interesting is the determination of the field from a known source (AKA the Forward Problem) versus the determination of the source from a known field (AKA the Inverse Problem). Whereas the forward problem is simple and solutions may be obtained through calculations, the inverse problem poses a problem. The lack of uniqueness to the inverse problem means the solution requires interpretation, which may be subjective. We may also apply a mechanism for the interpretation; this mechanism is known as an AI. However, this facet of AI (document classification) is only the surface of the field.

Damon Horowitz gave a recent presentation at TEDxSoMa called “Why machines need people”. In it, he says that AI can never approach the intelligence of humans. He gives examples of AI systems, like classification and summarization. He explains that those systems are simply “pattern matching” without any intelligence behind them. If true, perhaps the subjective interpretation of inverse problems is welcomed over the dumb classification. Through experience, the interpreters may have more insight than one can impart on an algorithm.

However, what Damon failed to mention was that most of those AI systems built to do small tasks is known as weak AI. There is a whole other field of study for strong AI, whose methods of creating intelligence is much more than “pattern matching”. Proponents of strong AI believe that human intelligence can be replicated. Of course we are a long way off from seeing human-level AI. What makes human intelligence hard to replicate? Can it be simulated? What if we created a model of the human brain, would it be able to think?

  • Mar 11 2012: Several years ago Congress funded a study to attempt to determine at what point Computers might become Sentient. My recollection is that it was quietly put into Law only to have the Religious Right wake up and repeal it. This discussion is full of Opinions and Assertions with little more than passion and feeling to back those up. IM

      Mar 11 2012: Very true, this discussion is full of opinions with passion backing it up. This is what I want to try to get above. These feelings or passions are due to what we classify as "qualia". It is hotly debated whether we can explain whether qualia is something systematic and explainable, thus measurable with a machine, or whether it's something unexplainable and thus truly an aspect that makes humans unique (thus sentient and conscious and unreproducible).
