Fun fact: I took the photo she used as a cover for one of her books, she asked me if she could use it and I said I'd like to be compensated and her response was something akin to "oh I was just asking assuming you'd say yes, I'm going to do it anyway". Nobody's perfect, maybe she regrets it, and it hasn't really crossed my mind in years, but I guess it still sort of irks me to be reminded of it. Anyway if anyone need…

Just an itsy bitsy little bit of copyright infringement :)

"Never before in my life had I seen so many smart people working on the same goal" I'm not sure why but the assumptions and naivety in this opening line bothers me. There are plenty of goals and problems that orders of magnitude more people are working on today.

But the author hadn't seen them in their life

Maybe she hasn't watched the Oppenheimer movie yet :D

Sounds like a great motivation for academic researchers to find a way to train LLMs with less compute. Or maybe invent something better than transformers. A brain trains on 20 Watts after all.

That's a hardware difference. Brains run at a very low clock speed and make up for it with massive parallelism. They also don't suffer from the vonn neumann bottleneck - today's computers spend most of their time and energy shuffling the network in and out of memory. I believe that better hardware architectures will have more impact on AI than better neural network architectures.

Pretend you have any hardware you want, today. What would you do with it? What model would you train? How do you know available hardware is the bottleneck and not model architecture?

I have a hard time understanding why mechanistic interpretability has so few eyes on it. It's like trying to build a complex software system without logging or monitoring. Any other improvements you want to make on the system are going to just be trail and error with luck. The hallucination problem is one where interpretability of a model might be able to identify the failure modes that we need to address. Really any AI problem could likely be aided by a scalable approach to interpretability that is just as mundane feeling as classical software observability.

My feeling is that GOFAI had a real problem with representing uncertainty, and handling contradiction. So, we tried to approach it theoretically, with fuzzy logic and probability and so on. But the theoretical research on uncertainty didn't reach any clear conclusion. Meanwhile, the neural nets (and ML) researchers just trucked on, with more compute power, and pretty much ignored any theoretical issues with uncertain…

I think that ascribes way too much meaning to hallucinations, which are the artifact of a big fancy markov chain doing what you'd expect a big fancy markov chain to do.

I don't get your argument about the frame problem. Maybe it's like squeezing a big pillow inside a small bag. A bulge forms that won't fit. It's the frame problem. Turn the pillow around, squeeze it into the bag again: a bulge now forms on the opposite side: it's the hallucination problem. I can see how one could be the solution to the other. Hallucinations as a lack of rules.

Just another random anecdotal experience with Chip. I was interviewing with Claypot.ai and when I met her for my first conversation, she was on a walking treadmill and very clearly was more interested in a Slack conversation she was having. She moved me on to the next round which I irrefutably bombed and was respectfully told that I wouldn't be moving on which was the right decision, but I'll never forget watching he…

It’s possible they were taking notes on the second monitor. Many interview coaches recommend taking notes during the interview to capture the response, largely verbatim, so that candidates can be fairly compared afterwards.

I've taken notes in plenty of interviews (and make sure to call it out ahead of time) but taking notes verbatim sounds absolutely terrible for both sides. A good interview is a conversation, and it's incredibly hard to do that if you're trying to transcribe the other half.

I think it's not possible to get rid of hallucinations given the structure of LLMs. Getting rid of hallucinations requires knowing how to differentiate fact from fiction. An analogy from programming languages that people might understand is type systems. Well-typed programs are facts and ill-typed programs are fictions (relative to the given typing of the program). To eliminate hallucinations from LLMs would require…

While I'm definitely not going to argue that LLMs are inherently 'thinking' like people do, one thing I do find pretty interesting is that all this talk about hallucinations and bias seems to often conveniently ignore the fact that people are often even more prone to these exact same problems - and as far as I know that's also unlikely to be solved. ChatGPT is often 'confidently wrong' - I'm pretty sure I've been con…

Indeed but people who are confidently wrong in good faith so to speak don't make up science paper titles.

A type system is for internal consistency though. Facts are about external consistency with real world data. And even then facts are always a social augmentation in that they are always captured in a given social context, and by that I include the lenses of theoretical frameworks and axiomatics. They always have a spin they can lose when considered from another standpoint and at the very minimum they are conditioned by attention and relevancy, and it has everything to do with our current representation of the world and nothing with the world itself.
