This post is the second in a series of three posts, each of which discuss the fundamental concepts of Artificial Intelligence. In our first post we discussed AI definitions, helping our readers to understand the basic concepts behind AI, giving them the tools required to sift through the many AI articles out there and form their own opinion. In this second post , we will discuss several notions which are important in understanding the limits of AI.
Strong and weak AI
The Turing Test

The Chinese Room Argument
|Figure 3. The Chinese Room mental experiment. Does the person in the room understand Chinese?|
The key question here is whether you understand the Chinese language. Whatyou have done is received an input note and followedinstructions to produce the output, without understanding anything aboutChinese. The argument is that a computer can never understand what itdoes, because – like you – it just executes the instructions of asoftware program. The point Searle wanted to make is that even if thebehavior of a machine seems intelligent, it will never be really intelligent.And as such, Searle claimed that the Turing Test was invalid.
The Intentional Stance
To what extend can machines have “general intelligence”?
