Machine Intelligence and Human Stupidity (The Turing Test Revisited)
- The Turing test was about deciding when a computer has become intelligent: when its behavior is indistinguishable from the behavior of a human being (said Turing).
- The implicit assumption was that it takes a smarter machine.
- But there's another way to pass the Turing test: make dumber humans.
- Human intelligence is not "exploding" but imploding.
- Humans have always become dependent on the tools they invented. When they invented writing, they lost memory skills. On the other hand, they gained a way to store a lot more knowledge and to broadcast it a lot faster. Ditto for all other inventions in history: a skill was lost, a skill was acquired.
- In practice, however, we cannot replay history backwards and we will never know what the world would be like if humans had not lost those memory skills. Indirectly we assume that the world as it is now is the best that it could have been. In reality, over the centuries the weaker memory skills have been driving an explosion of tools to deal with weak memory. Each tool, in turn, caused the decline of another skill. It is debatable if writing was worth this long chain of lost skills.
- This process of "dumbization" has been going on throughout society and accelerated dramatically ("exploded") with the digital devices. The computer caused the decline of calligraphy. Voice recognition will cause the decline of writing. In a sense, technology is about giving dumb people the tools to become dumber and still continue to live a happy life.
- What can machines do now that they could not do 50 years ago? They are just faster, cheaper and can store larger amounts of information. These factors made them ubiquitous.
- Machines are not getting any smarter (just faster) while humans are getting dumber; hence very soon we will have machines that are smarter than humans but not because the machines got smarter.
- It is not only that this enabled humans (many more humans) to use them; but also that this enabled humans (many more humans) to digitize huge amounts of knowledge. That knowledge originally came from someone who was "intelligent" in whichever field. Now it can be used by just about anybody who is not "intelligent" in that field. This "user" has no motivation to actually "learn": it can just "use" somebody else's intelligence. The "intelligence" of the user decreases, not increases.
- Worse: humans become ever more dependent on the machines. What is "intelligent" is not the machine, but the combination of the machine and the human who uses it.
- The Turing Test is a self-fulfilling prophecy: as we (claim to) build "smarter" machines, we make dumber people.
- The combination of smartphones and websites offers a glimpse of a day when one will not need to know anything because it will be possible to find everything in a second anywhere at any time. One will only need to be good at operating that one tool. That tool will be able to access an almost infinite library of knowledge.
- The tool/machine per se will not be particularly intelligent. The user of the tool will be even less intelligent.
