Today I decided to make a test to see if ChatGPT (through TalkAI, as I cannot register on ChatGPT, as I don't have a cell phone) is intelligent, like
many people say, or not.
I presented to it a know problem, the wolf, goat, cabbage problem, that I presented this way.
A man goes to the market and buys a guard dog, a sheep and some vegetables. To return home he has to cross a river in a small boat. The boat can
only take the man and one of the three items he bought. But he cannot leave the dog alone with the sheep, as the dog could kill the sheep, and he
cannot leave the sheep alone with the vegetables, as the sheep could it them.
How does the man put all the items safely on the other side of the river?
ChatGPT's answer was:
The man can solve the problem by following these steps:
The man first takes the sheep across the river and leaves it on the other side.
The man then returns alone to the original side to get the guard dog.
The man takes the guard dog across the river to the other side, but he cannot leave the dog alone with the sheep.
The man leaves the guard dog on the other side of the river and takes the sheep back to the original side.
The man now leaves the sheep on the original side and takes the vegetables across the river.
The man leaves the vegetables on the other side with the guard dog and returns to the original side one final time.
The man takes the sheep across the river for the last time and leaves it on the other side with the vegetables and the guard dog.
Now, all three items - the guard dog, sheep, and vegetables - are safely on the other side of the river.
Next, I presented it with a variation:
A man goes to the market with his son. He buys a monkey and some food. To get back home he has to cross a river on a small boat that can carry only
one person and one of the items he bought or two persons. He cannot leave his son alone with the food, as he could eat it. He cannot leave the monkey
alone with the food, as it could eat it. How does the man get to the other side with all the items and his son?
ChatGPT failed to solve the problem, presenting this "solution":
The man takes the monkey with him on the first trip across the river and leaves it on the other side. Then he returns alone to the original side
and takes his son with him on the second trip across the river. The man leaves his son on the other side and takes the monkey back to the original
side. He leaves the monkey on the original side and takes the food with him on the third trip across the river. Finally, he leaves the food with his
son on the other side and returns alone to the original side for the last time. Now, he can bring the monkey to the other side on the fourth and final
trip.
That fails on the first crossing, as the man leaves the boy alone with the food. It also fails near the end, when the man leaves his son and the food
on the other margin and comes back to take the monkey.
I pointed that the solution was wrong and presented the problem again.
ChaGPT's answer was, again, wrong.
The solution to this problem involves a series of carefully planned trips across the river. Here's the step-by-step process:
The man takes the monkey across the river first and leaves it on the other side.
The man goes back across the river alone.
The man takes the food across the river and leaves it with the monkey on the other side.
The man takes the monkey back across the river.
The man leaves the monkey on the starting side, and he takes his son across the river.
The man leaves his son on the other side and goes back across the river.
The man takes the monkey across the river one final time.
Now, all the items (monkey and food) as well as his son have made it across the river safely.
He made the same mistakes.
So, as anyone can see, ChatGPT is not intelligent, as an intelligent system would be able to extrapolate the solution of the first problem to the
second. Any normal person would be able to learn how to solve the second problem when presented with the solution for the first.
ChatGPT and similar systems are AI language models, they only "know" how to talk, they are not intelligent, although artificial intelligence was
used to create them.
