The result is hilariously wrong in all sorts of way: it doesn't understand what "vegan" means, it gives the wrong descriptions, and it carries stuff from the shore where it wasn't.

Here's what ChatGPT told me (I used "wolf" instead of "lion"):

"This is a similar problem to the classic river crossing puzzle, but with a few different elements to consider. Here's one possible procedure to solve this riddle:

1. The man takes the cabbage across the river and leaves it on the other side.

2. The man goes back alone and takes the wolf across the river, leaving it with the cabbage on the other side. It's important to note that the wolf is a vegan and will not eat the cabbage.

3. The man goes back alone and takes the goat across the river, leaving it on the other side.

4. The man goes back to the original side and picks up the cabbage, bringing it across the river to join the others.

5. Finally, the man goes back to the original side and picks up the wolf, bringing it across the river to join the others.

In this way, all of the man's belongings have been safely transported to the other side of the river, without the wolf eating the goat or the cabbage being destroyed."

Gpt4 posted above: edit: which is still wrong !!

To solve this puzzle, the man must follow these steps to transport his belongings across the river without any of them being harmed or eaten:

The man takes the meat-eating goat across the river first, leaving the vegan wolf and the cabbage on the initial shore.

He then returns alone to the initial shore.

Next, the man takes the cabbage across the river. Upon arriving on the other shore, he leaves the cabbage but takes the goat back with him to the initial shore.

The man then takes the vegan wolf across the river, leaving it with the cabbage on the other shore.

He returns alone to the initial shore.

Finally, the man takes the meat-eating goat across the river one last time.

Now, all his belongings are safely on the other shore: the cabbage, the vegan wolf, and the meat-eating goat.

> The man takes the meat-eating goat across the river first, leaving the vegan wolf and the cabbage on the initial shore.

GPT-4 failed to consider that the vegan wolf will eat the cabbage if left alone!

Which wrong by the way.

GPT4 is a valuable tool but it's not any form of general AI. It doesn't need to be in order to have a big impact.

Whether the current direction of research can take us there, nobody knows yet.
