If I'm following correctly, they trained a single model with multiple training paradigms and then the single model could perform token predictions for multiple dissimilar token sequences for specific tasks. Seems like it is a straightforward result.

Well… straightforward in a way, yes. But the scale of learning is huge especially with this diverse set of tasks. Not totally unexpected, but certainly not clear that it would work with current networks and sizes.

Right, exactly. Something that seemed like it should work but no one had ever tried it.

Slowly but surely we're moving towards general AI. There is a marked split across general society and even ML/AI specialists between those who think that we can achieve AGI using current methods and those who dismiss the possibility. This has always been the case, but what is remarkable about today's environment is that researchers keep making progress contrary to the doubter's predictions. Each time this happens, the AGI pessimists raise the bar (a little) for what constitutes AGI.

Just in the last five years, here are some categories of pessimistic predictions that have been falsified:

- "AI/ML can't solve scientifically useful problems" - then AlphaFold changed the protein folding field

- "We're entering an AI winter" [0] - then transformers continued to show promise across multiple domains

- "ML models can't perform creative work" - then came GANs, large language models, DALL-E, and more.

- "Generative ML models are just memorizing the dataset!" - then came multiple studies showing this to be false for well trained GANs, diffusion models and other types of generative models. Take a look at DALL-E 2 generated images of "a bear putting on a shirt in H&M".

- "AGI is impossible - look at language models, they have no understanding of the world and make silly mistakes" - the second part is true, large language models are artificially limited due to being language-focused. Nowadays there are approaches such as Gato and other multi-modal models. Humans develop intuition through multiple sources of information: sight, sound, smell, and touch. Given enough multi-modal context I'm confident multi-modal models will be able to show human-like intuition.

I'm not anti-skeptic. Skepticism is essential to all good science. I think the danger of skepticism with respect to AGI is that we're being complacent. Given the trajectory of improvements in machine learning, we should start preparing for a world where AI is indistinguishable, or far superior, to human intelligence.

AlphaFold is a big deal, but AI in science has been a really hot topic in the past almost decade.

Also, I still wouldn’t call AlphaFold really “intelligence”, it’s doing structure prediction which is cool but it’s a long way to scientific intelligence

This!! Can’t agree more. AI will continue to surprise us until it takes over.

Is today the day?

Date Weakly General AI is Publicly Known: https://www.metaculus.com/questions/3479/date-weakly-general...

(I really like the framing of "weakly general AI" since it puts the emphasis on the generality and not whether it's a superintelligence)

Edit: Probably not today, but mostly because 1.2B parameters isn't enough to get it the high winograd scores that PaLM etc have. But it seems pretty clear you could scale this architecture up and it will likely pass. The question is when someone will actually train a model that can do it

The closer we get, the more alarming the alignment problem becomes.

https://intelligence.org/2017/10/13/fire-alarm/

Even people like Eric Schmidt seem to downplay it (in a recent podcast with Sam Harris) - just saying “smart people will turn it off”. If it thinks faster than us and has goals not aligned with us this is unlikely to be possible.

If we’re lucky building it will have some easier to limit constraint like nuclear weapons do, but I’m not that hopeful about this.

If people could build nukes with random parts in their garage I’m not sure humanity would have made it past that stage. People underestimated the risks with nuclear weapons initially too and that’s with the risk being fairly obvious. The nuanced risk of unaligned AGI is a little harder to grasp even for people in the field.

People seem to model it like a smart person rather than something that thinks truly magnitudes faster than us.

If an ant wanted to change the goals of humanity, would it succeed?

given that the same model can both: 1. tell me about a cat (given a prompt such as "describe a cat to me") 2. recognize a cat in a photo, and describe the cat in the photo does the model understand that a cat that it sees in an image is related to a cat that it can describe in natural language? As in, are these two tasks (captioning an image and replying to a natural language prompt) so distinct that a "cat" in an im…

Definitely possible. OpenAI's CLIP model already embeds images and text into the same embedding space.

I don't know exactly how this particular model works but it is creating cross modal relationships otherwise it would not have the capacity to be good at so many tasks.

What I really want to know is what kind of robot arm motion is produced when the network is given a cat image to classify. More specifically, what kind of insights has it learned from one control domain that it then applied to another?

I imagine that the simulated 3D environment and the actual control of the robot arm must have some degree of interconnection neurally.
