I saw the name of the blog owner (A "Timothy B. Lee") and was surprised to see that the ~70 year old inventor of HTTP and the web had such an active and cutting-edge blog.

#192I'm not sure why people on HN (of all places) are so divided regarding the perception of AI/ML. I have not seen anything like it before. We literaly had not system or way of even doing things like code generation based on text input. Just last week i asked for a script to do image segmentation with a basic UI and claude just generated that for me in under 1 Minute. I could list tons of examples which are groundbreaki…
> Just last week i asked for a script to do image segmentation with a basic UI and claude just generated that for me in under 1 Minute. Thing is we just see that it's copy pasting stack overflow, but now in a fancy way so this is sounding like "I asked Google for a nearby restaurant and it found it in like 500ms, my C64 couldn't do that". It sounds impressive (and it is) because it sounds like "it learned about navig…
You have the wrong idea of how an LLM works. Its more like an model that iteratively finds associating / relevant blocks. The reasoning are the iterative steps it takes.

I'm following LLMs, AI/ML for a few years now and not just on a high level. There is not a single system out there today which can do what claude can do. I stil see it for what it is: A technology i can communicate/use with natural language and get a very diverse of tasks done. From writing/generating code, to svgs, to emails, translation etc. etc. etc. Its a paradigma shift for the whole world literaly. We finally h…
LLMs are great at tasks that involve written language. If your task does not involve written language, they suck. That's the main limitation. No matter how hard you push, AI is not a 'do everything machine' which is how it's being hyped.

#194AI for science is industrial scale P hacking. Dump in all the world's knowledge in to an AI and see what falls out.

It’s why it keeps looking exactly like NFT’s and crypto hype cycles to me: Yes the technology has legitimate uses, but the promises of groundbreaking use cases that will change the world are obviously not materialising and to anyone that understands the tech it can’t. It’s people making money off hype until it dies and move on to the next scam-with-some-use.
> to anyone that understands the tech it can’t. This is a ridiculous take that makes me think you might not « understand the tech » as much as you think you do. Is AI useful today ? That depends on the exact use case but overall it seems pretty clear the hype is greater than the use currently. But sometimes I feel like everyone forgets that ChatGPT isn’t even 3 years old, 6 years ago we were stuck with GPT-2 whose mo…
If there is a single objective right answer, the model should output a probability of 1 for it, and 0 for everything else. Ex. If I ask "Is a sphere a curved object?" The one and only answer is "100% yes" not "I am 99% sure it is" (and once in a while actually say it isn't)
This is pretty much impossible to achieve with current architectures (which aren't all that different to those of old, just bigger). If they did, then they'd be woefully overfitted. They can't be made reliable. Anyone who understands the tech does know this.

There's an easy fix for that: Choose a smaller (more appropriate) P.

I agree it's completely meaningless. At this point I think marketing would label a toilet fill valve as "AI".
Well the "smart toilet" is definitely a thing you can buy today: > The integration of Artificial Intelligence (AI) and the Internet of Things (IoT) in bathroom fixtures, particularly toilets, is shaping the future of hygiene, convenience, and sustainability.

Re: AI in my plasma physics research didn’t go the way I expected
#200Does anybody else find it peculiar that the majority of these articles about AI say things like "of course I don't doubt that AI will lead to major discoveries", and then go on to explain how they aren't useful in any field whatsoever? Where are the AI-driven breakthroughs? Or even the AI-driven incremental improvements? Do they exist anywhere? Or are we just using AI to remix existing general knowledge, while making…
There's hype, then there's the understanding that you never use version 1.0 of a product. In this sense, AI as we know is barely in an alpha version. I think the authors you're referring to understand the marketing around AI overstates its usefulness, but they are hopeful for a future where AI can be helpful.
