"statistical re-mixer" doesn't describe these systems very well. I see this complaint a lot, that supposedly DL models can only manipulate existing content without creating anything of their own. That's just false, unless your standard for originality is so high that humans can't reach it either.

These models that have hundreds of billions of "synapses", it's not very shocking to me that they can learn the abstract form of concepts. In fact, it's kind of beautiful that human concepts have this mathematical nature. It vindicates Plato, and disappoints everyone who has claimed that language and meaning is arbitrary.

But the main issue here is that for every conceivable empirical test we can perform, you'll still make the same complaint. Even after it's demonstrated better ToM abilities than you, by predicting and explaining other people's mental states better than you can, you'll say the same thing.

Maybe it's because you think that "understanding" requires not just accuracy, but having a certain kind of inner experience that a human could relate to.

Yes, I understand that it can appear to synthesize something new, and no, I'm not looking for some inner experience.

I'm looking for it to show an ability to wield not only a set of strings (with language associations), but something actually like the platonic ideals - objects, with properties and relations.

A few errors show quickly there is no such concept being weilded.

>> I saw a fine example of this failure the other day: "Mike's mom has four kids. three are named Danielle, Liam, and Kelly. What is the fourth kid's name?" ChatGPT's reply is explanation of how there isn't enough info in question to tell. Told "The answer is in the question.", ChatGPT just doubles down on the answer. (Sorry, couldn't find the original example)

>> "My sister was half my age when I was six years old. I'm now 60 years old. How old is my sister?" ChatGPT: "Your sister is now 30 years old". [0]

>> Or this one where ChatGPT entirely fails to understand order/sequence of events. [1]

Or a plethora of math problem fails found...

Similarly, the image "AI"s fail to understand relationships between objects (or parts of one object), and cannot abstract a particular person's image from a photo, showing it has no understanding of what is a body... (I can look those up if necessary).

And, of course, the answers are entirely untethered from reality - it is completely by chance whether the answer is correct or just wrong. It is run through a grammatical filter/generator at the end so it's usually grammatical, but no sort of truth filter (or ethical filter for that matter either).

I don't expect some abstract experience, I expect it to be able to break down it's work into fundamental abstract concepts and then construct an answer, and this it cannot do, or it would not be making these kinds of errors.

I would have given similar examples to show that ChatGPT makes the same kinds of mistakes that humans do. The first one is good, because ChatGPT can solve it easily when you present it as a riddle rather than being a genuine question. Humans use context and framing in the same way; I'm sure you've heard of the Wason selection task: https://en.wikipedia.org/wiki/Wason_selection_task

When posed as a logic problem, few people can solve it. But when framed in social terms, it becomes apparently simple. This shows how humans aren't using fundamental abstract concepts here, but rather heuristics and contextual information.

The second example you give is even better. It's designed to trick the reader into thinking of the number 30 by putting the phrase "half my age" before the number 60. It's using context as obfuscation. In this case, showing ChatGPT an analogous problem with different wording lets it see how to solve the first problem. You might even say it's able to notice the fundamental abstract concepts that both problems share.

The third problem is also a good example, but for the wrong reason: I can't solve it either. If you had spoken it to me slowly five times in a row, I doubt I could have given the right answer. If you gave me a pencil and paper, I could work through the steps one by one in a mechanical way... but solving it mentally? Impossible for me.

> It is run through a grammatical filter/generator at the end so it's usually grammatical, but no sort of truth filter (or ethical filter for that matter either).

I kind of thought it did get censored by a sort of "ethical filter" (very poorly, obviously), and also I wasn't aware of it needing grammatical assistance. Do you remember where you heard this?

Here's my chat with it, if you're interested: https://pastebin.com/raw/hQQ8bpsB

But comparing 1 human to 1 GPT is mistaken to begin with. It's like comparing 1 human with 1 Wernicke's area or 1 angular gyrus. If you had 100 different ChatGPTs, each optimized for a different task and able to communicate with each other, then you'd have something more similar to the human brain.
