Machines of Loving Grace

May 13, 2019

The title of this post is identical to the title of an excellent book by John Markoff. The subtitle is “The Quest for Common Ground.” The common ground referred to is that between humans and robots. The book covers, in excruciating detail, the development of artificial intelligence from the days of J.C.R. Licklider to 2015.

The book covers two lines of development. One from John McCarthy, which Markoff terms Artificial Intelligence (AI) and the other by Douglas Englebart, which Markoff terms Intelligence Augmented (IA). The former is concerned with making computers as smart as they can be, and the latter is concerned with using computers to augment human intelligence.

Markoff does not break down AI any further, but it needs to be. AI has been used by psychologists to model human cognition. So the ultimate goal here is to develop an understanding of human cognitive processes. AI has been quite informative. In attempting to model problems such as human vision, psychologists realized that they had overlooked some critical processes that were needed to explain perception. One should also regard AI as being a tool needed to develop theories of psychological processes.

There are also two types of AI. One is known as GOFIA, “Good Old Fashioned Artificial Intelligence” where computer code is developed to accomplish the task. GOFIA was stymied for a while due to the computational complexity it faced. Judea Pearl, the father of decapitated journalist Daniel, is a superb mathematician and logician. He developed Bayesian networks that successfully dealt with this problem and GOFIA proceeded further on with this expedited approach (enter “Pearl” into the search block of the healthy memory blog to learn more about this genius).

The other type is, or are neural nets. Here neural nets are designed to learn how to to accomplish a task. The problem with neural nets is that the programmers do not know how to solve the problem, rather they know how to design a neural net that solves the problem. Nightmare scenarios where computers take over the world would be the product of neural nets. With GOFAI problems could be solved by deleting lines of code.

Augmenting intelligence IA is what HM promotes. Here computer code serves as a mental prosthetic to enhance human knowledge and understanding. IA, unless it was the intelligence of a mad scientist, would not constitute a threat to humanity.

It is true that AI is required for robots to perform tasks that are difficult, boring, or dangerous. But the goal of an AI system must be understood or undesired consequences might result.
