I feel like this megaphone about AI safety and creating a sense of doom is a strategy to increase importance of OpenAI and exaggerate the capabilities of LLMs. This era of “AI” is all about pretending that machines can think and the people working in these machines are prophets.
Many have argued for safety for decades. They’ve predicted and built the AI trajectory, they’ve been right, and we should listen.

then it wasn't a canonical Turing test. The preprint accurately describes and analyzes their (indefensibly bad) experiment, but the popular press has mischaracterized it.
The canonical test gives the interrogator two witnesses, one human and one machine, and asks them to judge which witness is human. The interrogator knows that exactly one witness is human. In that test, a 50% chance of a right answer means the machine is indistinguishable from human. (Turing actually proposed a lower pass threshold, perhaps for statistical convenience.)
But that study gave the interrogator one witness, and asked them to judge whether it was human. The interrogator wasn't told anything about the prior probability that their witness was human. The probabilities that a real human is judged human and that GPT-4 is judged human sum to >100%, since nothing stops that since it's not a binary comparison. So 50% has no particular meaning. The result is effectively impossible to interpret, since it's a function both of the witness's performance and of whatever assumption the interrogator makes about the unspecified prior.
Look the Turing test is very different depending on the details, and I think a lame 5min Turing test that doesnt really measure anything of i terest is a wirse concept than a 1 day adversarial expert team test thqt can detect AGI.
that said, support is being replaced by nothing in a lot of places. (oh, sometimes there's an annoying chatbot.)
But by simple definitions, from what I was thought in school to more rigorous versions - we’ve passed the test. https://humsci.stanford.edu/feature/study-finds-chatgpts-lat...
Turing's interrogator also gets to ask whatever questions they think will most effectively distinguish human from machine. Everything those authors asked must appear in the training set countless times (and also corresponds closely to likely RLHF targets), making it a particularly unhelpful choice.
Turing's test is a restatement of a now pseudoscientific behaviourism common at the time; and also, egregiously, places a dumb ape as the system which measures intelligence. If an ape can be fooled, the system is intelligent: people worshiped the sun and thought it conscious. People are desperate to analogise the world to themselves, it is a trivial thing to fool an ape on this matter.
Whatever one might make of this as a philosophical thought experiment, as a test for intelligence, its pseudoscience. What a person might, or might not believe, about a series of words sent across a wire isn't science and it isnt relevant to a discussion about the capabilities of an AI system. It is a measure, only, of how easily deceived we are.
There's no scientific account of the capacities of a system with intelligence, no account of how these combine, no account of how communicative practices arise, etc. None. Any such attempt would immediately expose the "test" as ridiculous.
General intelligence arises as skillful adaptive control over one's environment, through sensory-motor concept aquistion, and so on.
It has absolutely nothing to do with whether you can emit text tokens in the right order to fool a user about whether the machine is a man or a woman (turing's actual test). Nor does it have anything to do with whether you can fool a person at all.
No machine whose goal is to fool a user about the machine's intelligence has thereby any capacities. Kinda, obviously.
Turing's test not only displays a gross lack of concern to produce any capacities of intelligence in a system; as a research goal, it's actively hostile to the production of any such capacities. Since it is trivial to fool people; this requires no intelligence at all.
This isn't a generally accepted definition or process.
And indeed it seems to preclude people like Stephen Hawkins who had little control over his environment (or to be pedantic, people who had similar conditions from birth).
Any even plausible scientific account of what capacities ground intelligence would render this view false. Whatever capacities you want to grant, no plausible ones are compatible with Turing's view nor the Turing test.
Consider imagination. You can replace a faculty to imagine with a set of models of ({prompt, reply},) histories for a human observer who is only concerned with those prompts and those replies. But as soon as anything changes in the world, you have to imagine novel things (eg., SpaceX is founded, we visit mars, a new TV show is released...). So questions such as, "what would the latest SpaceGuys TV show be like if Elon handed just launched BlahBlahRocket5 ?" cannot be given fit answers). These require the actual faculty of imagination, along with being in the world and so on.
As soon as you enter a sincere scientific attempt to characterise these features, you see immediately that whilst modelling historical frequencies of human-produced data can fool humans, it cannot impart these capacities.
> So questions such as, "what would the latest SpaceGuys TV show be like if Elon handed just launched BlahBlahRocket5 ?" cannot be given fit answers
I don't understand this at all. ChatGPT can do a great job imagining a world like this right now, and there is no substantial difference in the output of a LLM based "imagination" vs a human based "imagination".
> These require the actual faculty of imagination, along with being in the world and so on.
I think you are implying by this that human's imagination requires a consistent world model and that because LLM's don't really have this they can't be intelligent. Apologies if I have misinterpreted this!
But human imagination isn't consistent at all (as anyone who as edited a fiction story will tell you). Our creative imagination process generates wrong thoughts all the time, and then we self-critic and correct it. It's quite possible for LLMs to do this fine too!
Basically I think my point is that I believe a perfect simulation of intelligence is intelligence, whereas I suspect you don't think it is, maybe?
It's quite possible these are profoundly naive individuals, with little understanding of the empirical basis of what they're doing.
eg., NLP LLMs model, eg., all books ever written using frequencies by which words co-occur at certain distances relative to other words.
But these words are about the world (, people, events, etc.) and these change daily in ways that completely change their future distribution (eg., consider what all people said about Ukraine/Russia pre/post a few hours of 2022).
The LLM has no mechanism to be sensitive to what causes this distribution shift, which can be radical for any given topic, and happen over minutes.
All models of conditional probabilities of these kinds end up producing models which are only good at predicting on-average canonical answers/predictions that are stable over long periods.
This sounds so logical and authoritative. And yet:
me> What event would cause a change in what all people said about Ukraine/Russia pre/post a few hours of 2022
GPT4O> A significant event that caused a drastic change in global discussions about Ukraine and Russia in 2022 was the Russian invasion of Ukraine, which began on February 24, 2022. This military escalation led to widespread condemnation from the international community, significant geopolitical shifts, and a surge in media coverage. Before this invasion, discussions were likely more focused on diplomatic tensions, historical conflicts, and regional stability. After the invasion, the discourse shifted to topics such as warfare, humanitarian crises, sanctions against Russia, global security, and support for Ukraine.
The point is a model whose training stopped in 2021 would not produce a history of ukraine (etc.) that a person writing in 2023 would.
The later GPTs are trained on the user-provided prompts/answers of previous GPTs, so this process (which isnt the LLM, but it's the activity of research staff at OpenAI) is what's inducing approximate tracking of some changes in meaning.
Whilst this works for any changes over-represented in the new training data, (1) the LLM isnt doing that, its the researchers; and (2) this process is vastly expensive and time-intensive; and (3) only tracks changes with a high word frequency in new data.
If you could run the months-long, 1GWh, 10s-million-USD training process each minutes of the day, you would resolve the inability of the model to track major news stores... but would not resolve its ability to track, say, the user changing their clothes.
The sensitivity to the model of stuff in the world arises because of humans preparing the training data to bring about apparent sensitivity. Absent the activity of these humans, the whole thing drifts gradually into irrelvance.
In context learning works fine for this (and does for the Russia/Ukraine change too).
But yes, sure. It can be outdated in the same way a person cut off from news can be.
We've never argued that a shipwrecked person who was unaware of news became less intelligent because of that, just that their knowledge is outdated.
Additionally, the whole point of machine learning is to make systems that learn so they remain useful.
It seems likely that a model in soon (one year? five years? one month? who knows..) will be able to continually watch video broadcast news and videos of your home, continually updating its model.
In this case it would understand both the Ukraine issue and what you are wearing. Is it now suddenly intelligent? It's true it might be more useful, but to me that is a different thing.
