LLM assisted education =/=> no empathy is taught human-to-human

I have a slightly different perspective based on how I've observed schools use Bloomy. Focused use of Bloomy has allowed teachers to deliver higher-touch support to students who need it most (it also helps that our system identifies common learning patterns so teachers can conduct small-group instruction).

Human empathy is not optional, but rather required. Furthermore humans need to make the connection between the academic skill that's being taught and the real world application or relevance of that skill.

So LLM-assisted education has the potential to help humans be MORE empathetic and deliver the higher-leverage aspects of education only humans can do, while freeing them up from some of the inefficient many-to-one skill instruction for discrete concepts.

Clearly we have different definitions of what constitutes an attack, that said, I know you're fighting an eternal uphill battle on HN so I'll rest my case. I will say that I find some of this kind of moderation very confusing. I feel that I often see folks going way harder than anything I've said today and there's no moderation hand-slaps visible. Possibly the sensitivity is greater here since it's a Launch HN thread…

> very confusing. I feel that I often see folks going way harder than anything I've said today and there's no moderation hand-slaps visible. You're quite right and of course it's confusing. But it has a simple, unsatisfying explanation: we can't read everything that gets posted here, let alone moderate it all. There's far too much for us to read even 10% of what gets posted here. If you see a post that ought to have…

> Btw, I'm going to try an experiment and respond to your GP comment with a non-moderation reply, just because I find the topic interesting, and also in the hope of communicating what I said above: the thoughtful component of the conversation is fine. (No obligation to reply of course.)

I had logged off to chill out a bit so missed that you wrote this. Sorry to admit my ignorance but I don't know what this means? I appreciate your engaging with me fwiw.

I'm sucked back into work for most of the rest of the day so if you don't see a reply from me that's why, I'm not off stewing in a huff.

This problem has been around a long time. Like many other HN users, years ago in primary school I became a problem for my teachers because the curriculum was too easy for me.

The school dealt with it by sitting me in front of a big box of color-coded dossiers called the SRA Reading Laboratory [1, 2] and telling me "read these at your own pace". The boxes looked just like this: https://sites.google.com/view/objects-of-school-days-past/sr... and may well have been kicking around since the 1960s.

The trouble was that "at your own pace" was code for leaving me alone in front of a box. I don't recall the reading being either interesting or hard, but it solved the problem for my teachers, since I wasn't the type to act out in class. The real lessons I got out of it were lessons in isolation and drudgery.

Looking back, I badly needed contact with an adult who could teach me things. That didn't happen—not then, and not much in later school years either. Was it the schools' fault? They simply didn't have the resources to give me the human instruction I needed.

Surely all agree that children need human contact, empathy, connection, meaningful teaching. But it doesn't help children if we hold to those principles without facing how resource-constrained this problem is. If we do that, then many children end up with nothing, or next to nothing, as happened to me long ago.

Years later, when I read a little history, older novels, and the like, I learned how the nobility had educated their children: not just with dedicated personal tutors but different ones for different subjects. That's what one would do if one could afford entirely human, entirely interactive instruction, and of course it was only available to the 0.0001%. When I read those passages I felt envy and shame at not having what I would (to this day) call a real education, and those feelings have never entirely gone away.

My point with this anecdote is: I don't think I would have been worse off if they had sat me in front of a computer instead of a box of boring readings produced by education researchers. And if the computer had had software that could adapt to me and my interests, so much the better. At least I would have learned things, even though I still would have suffered from lack of human connection that, at that age, I was unaware how much I needed.

Sorry, it just took me a long time to write what I wanted, plus I'm on a flight with slow wi-fi. It's there now: https://news.ycombinator.com/item?id=48982399.

No worries—I appreciate the exchange!

What's your take on Anki?

I've personally both had and seen great success with the Anki approach for specific terms (e.g., vocab flash cards). Spaced repetition is built into Bloomy based on similar principles. A little harder to get right as you're now spacing out skills/concepts rather than just word/definition/context. Something we hope to fine tune over time.

When I was in school I remember thinking, when the futuristic utopia we envisioned in the 2000s arrives, a great deal of people will teach. It will be normal for professionals in all fields to spend some portion of their time teaching. How could it be otherwise, in a civilization which intends to preserve its knowledge and wisdom?

I remember asking my math teacher for applications and she mumbled a non-answer with some embarrassment. It was only years later that I realized, well my god, she's never stepped foot outside of a school in her entire life, no wonder she doesn't know about applications. It would have been nice, I think, to have had some contact with folks who had!

(Later still, I realized that I had reinvented the father from first principles...)

The fastest, most surefire way to nuke your child's brain is to give them a screen.

There is certainly room for software to design a curriculum for the parent or teacher to use. We have tried (and failed) to find such a thing for our homeschool curriculum.

But giving the kid a screen? If you're even a midge honest with yourself, a screen will de-educate your child, leading to the opposite of the intended consequence.

What is your approach to evaluating LLM outputs?

A few things: First, every BloomyBot response streams through an inline safety classification, and then an independent second-pass audit sweeps every stored message — a deterministic rule layer merged with a separate LLM classifier, taking the highest-severity result. It flags three categories (crisis, distress, inappropriate) across every language we support, and confirmed flags alert the teacher and school. We also…
