# [ExI] GPT-4 on its inability to solve the symbol grounding problem

```So I'm trying to understand if my
interpretation is right. Let me describe again the picture. There are 3
panels. In the first panel there is a stylized drawing (it looks almost
like a cartoon from the 1800s) of a man looking at a strawberry. The
strawberry outside the man is grey (not sure what that represents but you
can give it a try). But there is a bubble cartoon coming out of the head of
the man where the strawberry now is colored in red. In the second panel
there is a perfect replica of the first panel but with the difference that
inside the bubble cartoon the strawberry is green. Finally, in the third
panel there is a robot that is still looking at the grey strawberry but
inside the bubble cartoon appears the word Red (with capitol R). Can you
interpretation of this picture? Ignore the one I gave previously and come
up with what you think it is the intent of the creator of this picture.

Based on the description provided, I can offer an interpretation of the
picture:

1.

First panel: The grey strawberry outside the man may represent the
objective nature of reality, independent of our perceptions. The red
strawberry in the thought bubble signifies the man's personal, subjective
experience of the strawberry. By coloring the strawberry red inside the
man's thought bubble, the artist may be illustrating that the man perceives
the strawberry as red.
2.

Second panel: The second panel, with the green strawberry in the thought
bubble, could represent another person's subjective experience of the same
object (the strawberry). This panel highlights the possibility that people
may perceive the same object in different ways, emphasizing the subjective
nature of perception.
3.

Third panel: The robot looking at the grey strawberry with the word
"Red" in its thought bubble suggests that the robot is processing the
information about the strawberry and identifying its color as "Red."
However, since the robot lacks subjective experiences, it can only
represent the concept of color using a symbol or word, rather than
perceiving the color directly like the human subjects in the first two
panels.

Overall, the picture seems to explore the nature of human perception and
subjective experiences, contrasting them with the more limited, symbolic
understanding of machines. It emphasizes the unique and personal way that
humans perceive and experience the world around them, and how this differs
from the information processing of machines.
