As someone who has been engaged in children's lives in the age range of 4-9 that have struggled with school, I can't imagine using AI being a net benefit to them. You know what helped me succeed in helping these children more than anything else? Listening to them. That's it. Listening to them to understand their viewpoint and perspective on the world, their interest areas, and the things they were curious about. Then you incorporate those things in how you teach them through direct one on one instruction. It's that simple. My niece, as an example, is now at the top of her class in most subjects and has realized she has a passion for history and geology.

Not every child has the benefit of involved adults in their life, but I'd rather solve that problem than think AI is going to fix this. You're proposing taking one of the most vulnerable populations in the country and manipulating them (intentionally or not) to be reliant on one of the most exploitative technologies that has ever existed. I don't think your intent is evil, but the product here is evil. Remember that the path to hell is paved with good intentions.

> No, you painted your knowledge as being comprehensive, which is absurd for anyone to claim. The arrogance is in asserting one’s personal knowledge as being absolute and complete.

I never made any such assertion. I left out the word "my" to make the fact that I was only referring to my own knowledge explicit, which should have been implicitly understood as we /all/ operate from the limits of our own knowledge, all of the time. Once again, you are taking an uncharitable read of my comments even after I've explicitly clarified my intent to be helpful to others. You should disengage from this comment thread and I think it's impossible for us to have a productive conversation if your prior is that I'm an arrogant asshole, despite the fact I'm freely giving of what I do know to help other people. Be better.

I feel like this is some sort of satire? There's no actual information or substance to anything on any page of that site.

I don't make the definition

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.

Heuristics work, why would you not rely on heuristics?

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 got stuck with a very large bill for bandwidth overages due to bots hammering my photo gallery on my website. With Cloudflare in front I've since been running my site for years off a $10/mo VPS.

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.
