intelligence [1]
n. the ability to derive information, learn from experience, adapt to the environment, understand, and correctly utilize thought and reason.
1. Fact. A computer, by definition, can only evaluate computable functions. For instance, it cannot decide the halting problem.
2. Hypothesis. The set of all functions that form the basis of intelligence is computable
3. Fact. It is not known that Hypothesis 2 is true.
4. Therefore, it is not knowable that a computer can be intelligent or never be intelligent unless Hypothesis 2 is proven.
The statement Some computers are already intelligent is false since Hypothesis 2 is not proven to be true yet.
The statement A computer can never be intelligent by definition assumes that Hypothesis 2 can never be proven to be true. This is a very strong statement without basis. Therefore, it is also conjecture.
The statement Every computer is intelligent by definition is false since it treats Hypothesis 2 as an axiom. So, it can be true only in a universe where Hypothesis 2 is true.
Therefore, my response is None of the above.
