作为一个一直从事 4-9 岁儿童生活的人，他们在学校里遇到了困难，我无法想象使用人工智能会给他们带来净好处。你知道是什么最能帮助我成功地帮助这些孩子吗？听他们说。就是这样。倾听他们的声音，了解他们对世界的观点和看法、他们的兴趣领域以及他们好奇的事情。然后，您将这些内容融入到通过直接一对一指导的教学方式中。就是这么简单。举个例子，我的侄女现在在大多数科目上都是班上的佼佼者，并且意识到她对历史和地质学充满热情。

并不是每个孩子都能从生活中成年人的参与中受益，但我宁愿解决这个问题，也不愿认为人工智能会解决这个问题。您提议让该国最脆弱的人群之一（有意或无意）操纵他们，让他们依赖有史以来最具剥削性的技术之一。我不认为你的意图是邪恶的，但这里的产品是邪恶的。请记住，通往地狱的道路是由善意铺成的。

> 不，你把你的知识描绘成全面的，这对任何人来说都是荒谬的。傲慢在于声称自己的个人知识是绝对和完整的。

我从未做出过这样的断言。我省略了“我的”这个词，是为了表明我只是明确地指代我自己的知识，这应该被隐含地理解为我们/所有人/一直在我们自己知识的限制下运作。再次，即使我已经明确澄清了我为他人提供帮助的意图，但您还是在无情地阅读我的评论。你应该脱离这个评论线程，我认为如果你之前认为我是一个傲慢的混蛋，我们就不可能进行富有成效的对话，尽管事实上我正在自由地奉献我所知道的东西来帮助其他人。变得更好。

Unknown to me, but something useful to know is that there is something smaller than microplastics called nanoplastics. The distinguishing factor is that nanoplastics are particles smaller than 1 micron, while microplastics are particles between 1 micron and around 5 millimeters. As your other respondent notes, at some point you're talking about single molecules. As plastics is an entire category and not a single thing, there's no one size where that happens, but some polymers have chains that are as little as 0.01 (1/100th of a) micron in size.

As far as I am aware, we have yet to have effective, replicable research on what if any biointeractions exist with nanoplastic particles, including single polymer chains.

Yep, I didn't mention that regarding RO, but any properly designed system will include remineralization as a final filtration stage to buffer the water.

Definitely switch to waxed string floss vs plastic floss made from Teflon. I wasn't aware of the fiber connection, would love to see a study here.

> You completely confuse plastics and linings with PFAS. They're not the same. Linings can contain bisphenols but that doesn't imply PFAS.

I don't confuse anything. Tin cans, soda cans, and other non-plastic packaging is lined with PTFE (e.g. Teflon, made from PFAS) and contains residual PFAS that leach into the food products. One of the most common non-metallic, non-traditional plastic food packaging is Tetra Pak which is entirely constructed from PTFE. Many paper packaging products are coated with an aerosol applied DWR coating which is entirely made from PFAS, which is even worse than DWR coatings on clothing for exposure. This is especially common in paper take-out containers. Microplastics and plasticizer leaching are a separate but also problematic issue, and luckily you can kinda kill two birds with one stone by making these lifestyle changes. Due to the water propellant and flow properties and easy aerosolization of PFAS derived coatings and liners they have quietly pervaded nearly every aspect of the product packaging industry, so it's not just "plastics", it /is/ PFAS.

> What's up with the haughty arrogance? It is both unjustified and wrong.

I don't know what you mean? I provided a helpful reply to the GPs question, and I pointed out the limits of current knowledge. There's no arrogance or haughtiness here. What's with the overly defensive and uncharitable response?

I'm not an expert here, but I care about this issue deeply and I track what I've spent to try to reduce my own family's exposure, and it's not insignificant. Beyond the up front and ongoing costs of things like filtration systems, there's a cost difference today between products which are packaged cleanly and those that are packaged in a way which cause exposure. It ballpark costs me somewhere around $40k/yr to minimize exposure, and I'm absolutely certain that the steps we've taken are still insufficient. I can't even imagine how the average person is supposed to avoid the health implications of exposure. We've allowed some of the largest corporations to poison our water and food supply with no repercussions and the full complicity of our own government. We're "cooked" in the terms kids use these days. Good luck to you all.

MSM is one of the highest risk activities you can do for bloodborne diseases. If this is discriminatory, life is discriminatory. Life is not fair, and there is nothing any artificially constructed social system will ever do to force mother nature's hands to make life fair. I fully support the rights of people to love and be in relationships with whoever they wish, but that doesn't mean you have the right to contaminate the blood supply due to the inherently high risk of your day-to-day life.

I have never been able to donate blood because of my travels due to their locations and frequencies. I am not going to give up travel to donate blood. MSM is a much higher risk activity than travel, and yet I am also excluded due to my lifestyle risk. It's not fair, but it is reasonable.

Yes, there are a few things you can do. In rough priority / proven benefit order:

1. Eliminate as many items as possible from your diet that make use of PFAS based components, such as plastic linings. This means don't buy groceries packaged in lined packaging, this means don't cook with Teflon pans, and it means don't drink water from plastic bottles or bottles lines with plastic.

2. Get a whole-home water filtration system that is certified (NSF 53 or similar standard) to reduce/remove PFAS and if possible, on top of this do under-sink RO for drinking/cooking which is certified (NSF 58 or similar) to remove PFAS and use glass or stainless steel reusable water bottles to take water outside your home.

3. Exercise regularly so that you sweat and drink lots of appropriately filtered water, donate blood and/or plasma regularly.

4. Eliminate clothing or other items in your wardrobe that are coated with DWR or similar coatings. Don't make use of any PFAS-derived treatments/plastics in your clothing. This is especially important during the process of washing your clothes, as this generates microplastics which are PFAS contaminated and you can ingest them via breathing.

Everything else is basically guesswork, these are the only things known to have any benefit. We mostly ingest PFAS due to contamination in the food and water supply. This contamination is unavoidable, but we can greatly reduce exposure by making smarter choices about packaging materials and cooking methods, and a big one is simply not drinking anything that you can't confirm has been properly filtered and packaged.

I'm a bit extreme, I even brew and bottle my own beer and other beverages like soda and water kefir/kombucha to avoid exposure to externally packaged products that may be contaminated with PFAS.

That's correct.

Does /anyone/ take notes in a personal context? I don't take notes when I catch up with friends, but neither does anyone else. It's a complete non-issue.

I can understand, especially in a medical context, being bothered by AI notetaking specifically because it implies your private information being handed off to a third-party where you cannot control it, rather than that an AI tool is processing it. That said, it is common practice in business to take notes or record calls. I take notes either by hand or type-written in nearly every meeting that I'm in. I often record my meetings. When it's entirely within my company, we have an internal (e.g. not third-party) AI transcription tool that I enable. When meeting with external entities, I either write notes, record audio, or have a designated person with me to write notes.

Taking minutes/notes in a meeting and then being accountable to follow-up on any action items out of that meeting is just standard business process across industries and across the globe. That's not what the author is referring to with their therapist, that's a very different context, but in the context most people on HN find themselves in, having someone take notes is not only not a big deal, it /should/ happen.

I think something important to consider as well is quality of basic services. I've been permanently remote since 2015, and I've moved three times since then. But as a remote worker, I spend most my time in my home and that means it needs high quality water, high quality air, high quality internet, and high quality electrical services. If I cannot get all of these, it's a non-starter. I have absolutely zero faith in getting all of these services of sufficiently high quality for the majority of homes listed on this site, and in many cases I would expect /none/ of these services to be sufficiently high quality. Most of these houses are located in places I would never live, they are essentially negative value locations (in very real terms, not just monetarily).

All that said, I live in one of the lowest cost of living major metros in the US, and I bought a house in an acceptably decent neighborhood w/ high quality water, electrical, and air, and 5 gigabit symmetric fiber service for under $300k. You don't need to spend millions to find an acceptable place to live when you work remotely, but that doesn't mean you want to live in a HUD foreclosure in some of the worst most blighted neighborhoods in the country where you can't rely on even basic services and are going to be immediately a target of violent crime.

I don't if anyone is doing this yet, but I think a small LLM w/ data sets for RAG reachable via APRS and LoRa would be very useful, not just as an individual but for the community around you.

I agree that drugs should be regulated, but that regulation should be primarily about ensuring that they are effective, safe when taken as instructed, and that they contain the ingredients they say that they do and don't contain ingredients that aren't listed.

It is not the government's responsibility, nor should it be, to try to solve the fact that someone can do something stupid with medication and harm themselves. Medication, by its very nature, interacts with and changes your body: that's the entire point. There is no way for something to be effective and also impossible to abuse or misuse. Regulating drug safety should always be based on following the instructions for how to use that drug.

That's not to say we can't do more the educate people, but ignorance should not lead to inaccessibility. There are tens of millions of people in this country that are fully capable of reading a box and following instructions and they should not have to live a worse quality of life because some people are not willing or able to do so.

There are people who don't know that Tylenol and acetaminophen are the same thing. That is not a reason for us to make everyone's quality of life and access to healthcare worse because some people are ignorant.

The desire to nanny-state things to the lowest common denominator is ruining everything, and it's a major driver for various problems all the way to the housing crisis and the cost of healthcare in the first place.

I have an Ergodox EZ I built as well as a Moonlander, but I ultimately decided split/tilt wasn't right for my wrists. I switched to an Arisu layout ergo single-frame keyboard and that is what I rely on to this day. The biggest win was going to a vertical mouse. I'm also a lover of the Model M and Model F, but these are not properly ergonomic in 2026 (and at 40+ years old).

Shoutout to the IV Works AV3/AV4 and the Evoluent vertical mouse for helping stave off surgery for another 6 years (and counting).

One of the bitter truths is that these types of things aren't easily replicated in other regions because of cultural differences. You have to have developed trust and accountability over decades or centuries in your culture that would support making long term decisions and both employees and customers believing you. It basically doesn't matter what Microsoft does, I would never believe them, and that disconnects their decisions from the outcomes.

As someone who loves using OpenCode w/ local Chinese open source models, this is basically my take on this as well. There's no way I would ever put a piece of proprietary Chinese software that gets full system control on anything important. This is definitely something I would only ever run sandboxed in a lab environment for toy projects, not for serious work. I feel only marginally better about Codex/Claude Code, hence my strong preference for local LLMs w/ OpenCode, but a proprietary approach to Chinese models is a hard no from me dawg.
