It's nice to hear from someone who knows what they're talking about that GPT-3 is just a fancy and expensive autocomplete. The hype in some circles about it went as far as comparing it to AGI at some point which is just ridiculous.

What evidence do I have that I'm more than a fancy autocomplete, myself? The use of squishy protestations, in lieu of objective metrics, make LeCun's argument rather unconvincing.

I think the difference between a large language model and a human intelligence is that the human may perform some extra computation to make additional connections on his own. But other than that, aren't we all just large language models?

Not even remotely close. The difference is so big that it's almost harmful to the discussion to compare the way humans think (which we still don't have great understanding of) and the way language models work.

I'm sure his group has done some rigorous research that I can't even understand. But in my experience, the few-shot learner attribute of GPT-3 makes it insanely useful. We have already found several use cases for it, one of which replaces 2 ML engineers. Yes, it's not perfect, but it's pretty good at many things, and REALLY easy to use.

Can you go into more details where it's useful? As your comment here goes directly against what's argued in the linked Facebook post. Also, if you've found a use case where GPT-3 replaces real humans, what did those humans actually spend their time on? Seems like either you're over-hyping GPT-3, or under-hyping humanity

The humans spent their time building a hideously difficult classification model. Out of the box GPT-3 worked better than the result of a year of their work.

I would be interested in hearing more about this, within the bounds of what you can share publicly. Most of the touted GPT-3 use cases I've seen to date have dried up or are still in limbo, so hearing about a real production use would be exciting!

Extremely complex classification task is all I can say

For anyone else who doesn’t want to deal with Facebook, here’s the post: Some people have completely unrealistic expectations about what large-scale language models such as GPT-3 can do. This simple explanatory study by my friends at Nabla debunks some of those expectations for people who think massive language models can be used in healthcare. GPT-3 is a language model, which means that you feed it a text and ask it…

High altitude planes going to the moon is a beautiful analogy. I think this is what I’ll use to explain to less technical friends why I think we’re still many years from self driving cars.

I agree some unrealistic expectations have been created due to people posting cherry picked output.

That said, I've spent a lot of time with it this month and think it will be an extremely useful tool for creative works of all types. It's not to a point where you can just tell it to write a blog post (yet!) but it can generate novel snippets, ideas, and variations that are actually usable. Unskilled creatives should be worried. Skilled creatives should incorporate it into their workflow.

Reading this is really interesting:

> GPT-3 doesn't have any knowledge of how the world actually works.

I think this is a philosophical question. There is a view that, basically, there is no such thing as knowledge, just language (or, at least, there is no distinction between knowledge and language). In this view, all there really is is language, which is mostly composed of metaphors and, ultimately, metaphors only refer to other metaphors, i.e. language is circular. In this view, not only is the ultimate, physical, concrete world beyond us but also we can't even talk about it. From this perspective, GPT-3 is not substantively different than what our minds are doing.

That view makes some strong claims (I don't find it convincing), but it's out there. A slightly different claim, though, is that "knowledge of how (we think) the world actually works" is encoded in language. To me, that seems trivially true. So, again, how you take this quote from LeCun depends on what you think knowledge is and your view of the relationship between knowledge and language.

I have been using that analogy to explain why Tesla is many years away from a self driving car. Several others are building something that is fundamentally different.

If you are nothing more than fancy autocomplete, then why should we argue with you?

GPT is not trying to make a point and is not capable of changing its mind. You, hopefully, are.

Edit: I don't think you should be getting downvoted because it's a valid (and interesting) question.
