I've generally found an inverse correlation between "understands AI" and "exuberance for AI".
I'm the only person at my current company who has had experience at multiple AI companies (the rest have never worked on it in a production environment, one of our projects is literally something I got paid to deliver customers at another startup), has written professionally about the topic, and worked directly with some big names in the space. Unsurprisingly, I have nothing to do with any of our AI efforts.
One of the members of our leadership team, who I don't believe understands matrix multiplication, genuinely believes he's about to transcend human identity by merging with AI. He's publicly discussed how hard it is to maintain friendship with normal humans who can't keep up.
Now I absolutely think AI is useful, but these people don't want AI to be useful they want it to be something that anyone who understands it knows it can't be.
It's getting to the point where I genuinely feel I'm witnessing some sort of mass hysteria event. I keep getting introduced to people who have almost no understanding of the fundamentals of how LLMs work who have the most radically fantastic ideas about what they are capable of on a level I have ever experienced in my fairly long technical career.
I'm sure you're already familiar with the ELIZA effect [0], but you should be a bit skeptical of what you are seeing with your eyes, especially when it comes to language. Humans have an incredible weakness to be tricked by language.
You should be doubly skeptically ever since RLHF has become standard as the model has literally been optimized to give you answers you find most pleasing.
The best way to measure of course is with evaluations, and I have done professional LLM model evaluation work for about 2 years. I've seen (and written) tons of evals and they both impress me and inform my skepticism about the limitations of LLMs. I've also seen countless times where people are convinced "with their eyes" they've found a prompt trick that improves the results, only to be shown that this doesn't pan out when run on a full eval suite.
As an aside: What's fascinating is that it seems our visual system is much more skeptical, an eyeball being slightly off created by a diffusion model will immediately set off alarms where enough clever word play from an LLM will make us drop our guard.
We get around this a bit when using it to write code since we have unit tests and can verify that it's making correct changes and adhering to an architecture. It has truly become much more capable in the last year. This technology is so flexible that it can be used in ways no eval will ever touch and still perform well. You can't just rely on what the labs say about it, you have to USE it.
Interesting observation about the visual system. Truth be told, we get the visual feedback about the world at a much higher data rat AND the visual about the world is usually much higher correlated with reality, whereas the language is a virtual byproduct of cognition and communication.
No one understands how LLMs work. But some people manage to delude themselves into thinking that they do.
One key thing that people prefer not to think about is that LLMs aren't created by humans. They are created by an inhuman optimization algorithm that humans have learned to invoke and feed with data and computation.
Humans have a say in what it does and how, but "a say" is about the extent of it. The rest is a black box - incomprehensible products of a poorly understood mathematical process. The kind of thing you have to research just to get some small glimpses of how it does what it does.
Expecting those humans to understand how LLMs work is a bit like expecting a woman to know how humans work because she made a human once.
I work in a space where I get to build and optimise AI tools for my own and my team's use pretty much daily. As such I focus mainly on AI'ing the crap out of boring & time-consuming stuff that doesn't interest any of us any more, and luckily enough there's a whole lot of low hanging fruit in that space where AI is a genuine time, cost and sanity saver.
However any activity that requires directed conscious thought and decision making where the end state isn't clearly definable up front tends to be really difficult for AI. So much of that work relies on a level of intuition and knowledge that is very hard to explain to a layman - let alone eidetic idiots like most AIs.
One example is trying to get AI to identify security IT incidents in real time and take proactive action. Skilled practitioners can fairly easily use AI to detect anomalous events in near real time, but getting AI to take the next step to work out which combinations of "anomalous" activities equate to "likely security incident" is much harder. A reasonably competent human can usually do that relatively quickly, but often can't explain how they do it.
Working out what action is appropriate once the "likely security incident" has been identified is another task that a reasonably competent human can do, but where AIs are hopeless. In most cases, a competent human is WAAAY better at identifying a reasonable way forward based on insufficient knowledge. In those cases, a good decision made quickly is preferable to a perfect decision made slowly, and humans understand this fairly intuitively.
I think there is a correlation between when you can you expect from something when I know their internals vs someone that doesn’t know but is not like who knows internals is much much better.
Example: many people created websites without a clue of how they really work. And got millions of people on it. Or had crazy ideas to do things with them.
At the same time there are devs that know how internals work but can’t get 1 user.
pc manufacturers never were able to even imagine what random people were able to do with their pc.
This to say that even if you know internals you can claim you know better, but doesn’t mean it’s absolute.
Sometimes knowing the fundamentals it’s a limitation. Will limit your imagination.
I'm a big fan of the concept of 初心 (Japanese: Shoshin aka "beginners mind" [0] ) and largely agree with Sazuki's famous quote:
> “In the beginner’s mind there are many possibilities, but in the expert’s there are few”
Experts do tend to be limited in what they see as possible. But I don't think that allows carte blanche belief that a fancy Markov Chain will let you transcend humanity. I would argue one of the key concepts of "beginners mind" is not radical assurance in what's possible but unbounded curiosity and willingness to explore with an open mind. Right now we see this in the Stable Diffusion community: there are tons of people who also don't understand matrix multiplication that are doing incredible work through pure experimentation. There's a huge gap between "I wonder what will happen if I just mix these models together" and "we're just a few years from surrendering our will to AI". None of the people I'm concerned about have what I would consider an "open mind" about the topic of AI. They are sure of what they know and to disagree is to invite complete rejection. Hardly a principle of beginners mind.
Additionally:
> pc manufacturers never were able to even imagine what random people were able to do with their pc.
Belies a deep ignorance of the history of personal computing. Honestly, I don't think modern computing has still ever returned to the ambition of what was being dreampt up, by experts, at Xerox PARC. The demos on the Xerox Alto in the early 1970s are still ambitious in some senses. And, as much as I'm not a huge fan, Gates and Jobs absolutely had grand visions for what the PC would be.
I think this is what is blunted by mass education and most textbooks. We need to discover it again if we want to enjoy our profession with all the signals flowing from social media about all the great things other people are achieving. Staying stupid and hungry really helps.
I think this is more about mechanistic understanding vs fundamental insight kind of situation. The linear algebra picture is currently very mechanistic since it only tells us what the computations are. There are research groups trying to go beyond that but the insight from these efforts are currently very limited.
However, the probabilistic view is very much clearer. You can have many explorable insights, both potentially true and false, by jıst understanding the loss functions, what the model is sampling from, what is the marginal or conditional distributions are and so on. Generative AI models are beautiful at that level. It is truly mind blowing that in 2025, we are able to sample from the megapixel image distributions conditioned on the NLP text prompts.
If you dig ml/vision papers from old, you will see that formulation-wise they actually did, but they lacked the data, compute, and the mechanistic machinery provided by the transformer architecture. The wheels of progress are slow and requires many rotations to finally reach somewhere.

Few years ago I had this exact observation regarding self driving cars. Non/semi engineers who worked in the tech industry were very bullish about self driving cars, believing every and ETA spewed by Musk, engineers were cautious optimistically or pessimistically depending on their understanding of AI, LiDAR, etc.
This completely explains why so many engineers are skeptical of AI while so many managers embrace it: The engineers are the ones who understand it.
(BTW, if you're an engineer who thinks you don't understand AI or are not qualified to work on it, think again. It's just linear algebra, and linear algebra is not that hard. Once you spend a day studying it, you'll think "Is that all there is to it?" The only difficult part of AI is learning PyTorch, since all the AI papers are written in terms of Python nowadays instead of -- you know -- math.)
I've been building neural net systems since the late 1980s. And yes they work and they do useful things when you have modern amounts of compute available, but they are not the second coming of $DEITY.
Linear algebra cannot be learned in a day. Maybe multiplying matrices when the dimensions allow but there is far more to linear algebra than knowing how to multiply matrices. Knowing when and why is far more interesting. Knowing how to decompose them. Knowing what a non-singular matrix is and why it’s special and so on. Once you know what’s found in a basic lower devision linear algebra class, one can move it linear programming and learn about cost functions and optimization or numerical analysis.
PyTorch is just a calculator. If I handed someone a Ti-84 they wouldn’t magically know how to bust out statistics on it…

Curiously some Feynman chap reported that several NASA engineers put the chance of the Challenger going kablooie—an untechnical term for rapid unscheduled deconstruction, which the Challenger had then just recently exhibited—at 1 in 200, or so, while the manager said, after some prevarications—"weaseled" is Feynman's term—that the chance was 1 in 100,000 with 100% confidence.
I mostly disagree with this. Lots of things correlate weakly with other things, often in confusing and overlapping ways. For instance, expertise can also correlate with resistance to change. Ego can correlate with protection of the status quo and dismissal of people who don't have the "right" credentials. Love of craft can correlate with distaste for automation of said craft (regardless of the effectiveness of the automation). Threat to personal financial stability can correlate with resistance (regardless of technical merit). Potential for personal profit can correlate with support (regardless of technical merit). Understanding neural nets can correlate both with exuberance and skepticism in slightly different populations.
Correlations are interesting but when examined only individually they are not nearly as meaningful as they might seem. Which one you latch onto as "the truth" probably says more about what tribe you value or want to be part of than anything fundamental about technology or society or people in general.
It's definitely interesting to look at people's mental models around AI.
I don't know shit about the math that makes it work, but my mental model is basically - "A LLM is an additional tool in my toolbox which performs summarization, classification and text transformation tasks for me imperfectly, but overall pretty well."
Probably lots of flaws in that model but I just try to think like an engineer who's attempting to get a job done and staying up to date on his tooling.
But as you say there are people who have been fooled by the "AI" angle of all this, and they think they're witnessing the birth of a machine god or something. The example that really makes me throw up my hands is r/MyBoyfriendIsAI where you have women agreeing to marry the LLM and other nonsense that is unfathomable to the mentally well.
There's always been a subset of humans who believe unimaginably stupid things, like that there's a guy in the sky who throws lightning bolts when he's angry, or whatever. The interesting (as in frightening) trend in modernity is that instead of these moron cults forming around natural phenomena we're increasingly forming them around things that are human made. Sometimes we form them around the state and human leaders, increasingly we're forming them around technologies, in line with Arthur C. Clarke's third law - that "Any sufficiently advanced technology is indistinguishable from magic."
If I sound harsh it's because I am, we don't want these moron cults to win, the outcome would be terrible, some high tech version of the Dark Ages. Yet at this moment we have business and political leaders and countless run-of-the-mill tech world grifters who are leaning into the moron cult version of AI rather than encouraging people to just see it as another tool in the box.
