heathrow83829··on Health AI Startup Has Helped Reverse Denied Health Insurance Claims
reversing denied health insurance claims only changes who pays for it (end of the day premiums will probably go up proportionatly), it does nothing to reduce the overall cost which is a much bigger problem.
heathrow83829··on Startups brag they spend more money on AI than human employees
The argument that AI guys are making about the coming mass unemployment goes like this: those companies that are spending on AI rather than humans may have a huge competitive advantage that allows them to take marketshare from human run companies and thus there's less and less demand for human labor.

But, how many businesses/sectors of the economy actually need to compete for marketshare? we assume it's nearly all of them. if that were the case, we'd see AI taking over much quicker.

heathrow83829··on Tim Cook's Impeccable Timing
>> the next era looks bright.

but what could they possibly build that hasn't been done on iphone and ipad yet? these devices seem finished to me. all the latest features on these devices are getting increasingly useless, to be honest.

are you imaging them creating whole new devices?

heathrow83829··on 40% of lost calories globally are from beef, needing 33 cal of feed per 1 cal
meat uses up enormous quantities of water. potatoes for instance use about 75 gallons to produce 2000 calories compared to say 1500 to 2500 gallons for 2000 calories of beef.
heathrow83829··on We need Post-Quantum Cryptography more than ever
they should go into more detail on what data specifically is suspectible to HNDL attacks as well as other attacks. they were pretty vague on that
heathrow83829··on The Looming College-Enrollment Death Spiral
Yup. I've also seen a number like that mentioned by the Moonshots podcast by peter diamantis.. they showed that quarter by quarter the placement rate for CS grads had declined every querter for the last 3 years from 93% at 91K per year down to 19% at about 65k. it was one of their last podcasts from about a week ago.
heathrow83829··on A new way to measure poverty shows the US falling behind Europe
the article doesn't explain how the math works. if min wage is 15$ an hour or 10$, how do they arrive at 1$ for 63 min???
heathrow83829··on OpenAI closes funding round at an $852B valuation
you gotta have some of all the above actually.
heathrow83829··on I am leaving the AI party after one drink
You are lucky that you have the luxury of being able to work at a normal pace and not be pressured to go "even faster".

My boss, is constantly saying "go faster, go faster". AI, is unfortunately the only way to keep up if you want to keep your job, this day and age.

heathrow83829··on Earthquake scientists reveal how overplowing weakens soil at experimental farm
to till or not to till, that's the question. one way to look at is check the yields that result from dig vs no dig. Charles dowding did exactly that. for seven years he had two plots, one where he dug and one where he didn't. in each one he added the same amount of compost and grew teh same crops on both sides.

Overall, the nodig plot harvest 10% more. but here's where it gets interesting. those yields were not uniformly spread across the vegetable types. if you dig into the data, you'll see, some did quite worse with dig and some did quite better. guess which ones did better on dig? Potatoes, Rutabagas, carrots and parsnips and cabbage all did better in Dig! roughly to the tune of about Potatoes 21%, carrots 21%, Rutabaga 14%, Cabbage, 11%, broad beans 10% better. it's all published in his books. Everything else did better with no dig. Shallots especially did 33% better with no-dig, ales 21% better, onions 22% better with no dig.

heathrow83829··on Meta acquires Moltbook
Sure they could develop it in a weekend, so could anyone else. but once a product has the initial userbase, that's not something a competitor can just copy. user acquision is the limiting factor to success, not writing code.
heathrow83829··on Layoffs at Block
that's not the job of a company. companies are suposed to be profit centered, their purpose is to make money.

what you're talking about is the role of government. govt should be supporting policies like you are suggesting, by for example allowing for universal basic income or uniersal basic land or services, etc.

heathrow83829··on Layoffs at Block
The biggest limiting factor is user acquisition. Just because you can build a competitor in a weekend doesn't mean you can easily acquire a user base. it's dam hard to get users even if your product is twice as good and your giving it away for free!
heathrow83829··on America vs. Singapore: You can't save your way out of economic shocks
there are still tribes in the amazon that have very little money, like the hazda. they may not call it retirement but they don't need to go to the office everyday.

Serious question, what makes us so addicted and dependent to money that we can't imagine any way of life without a lot of it?

heathrow83829··on America vs. Singapore: You can't save your way out of economic shocks
i think you can get a pretty decent prius from 5k to 10k and a fantastic nearly brand new tesla model 3 for 17K. That's what i did. it was 8 years old, practically brand new, FSD prepaid included! it drives me to work and i only paid 17K for it!
heathrow83829··on America vs. Singapore: You can't save your way out of economic shocks
you don't need to eat ramen. there are many cost effective options out there: oatmeal, beans, rice, you could grow your own fruits and vegetables, etc.

and as for the medical disaster: heart attack and stroke are actually preventable with a plant based diet (keep your LDL under 80 and you'll vastly decrease your chance of a heart attack). i know a lot of people will hate on that, but those are the facts and any evidence based nutritionist can tell you this.

heathrow83829··on Dinosaur Food: 100M year old foods we still eat today (2022)
my wife and I regularly eat lotus root, it's quite delicious and common in chinese cooking. the others not so much.

On a side note there are 1000s even 10s of thousand of edible plant based species that grow on the earth. i don't know how old they are though.

heathrow83829··on The only moat left is money?
i would argue that reach has already been the biggest limiting factor for the last 10 even 20 years.
heathrow83829··on The Future of AI Software Development
isn't it just one more step up the hierarchy. 10 years ago most developers have forgotten how to code in machine language because you didn't need to know it. Now, we're jsut going one step higher.
heathrow83829··on Tesla's 45 Austin Robotaxis now have 14 crashes on the books since June 2025
this is misleading because they're not comparing apples to apples.

the insurance companies are looking into all the details I'm sure to be able price the risk accordingly. Lemonade is putting their money where their mouth is and it's pricing FSD miles at 1/2 the rate of manned driving. that's because FSD gets 1/2 the number accidents per mile.

heathrow83829··on U.S. had almost no job growth in 2025
>>> "Still, Wednesday’s report also shows that not nearly as many jobs were added in 2025 as thought and last year will go down as the worst year for hiring since 2020, or since 2003 outside of a recession."

Almost no jobs were added net and the few that were, were all in health care, 131K i think the article said.

what i find interesting is that unemployment percent still looks low. is it accurate? even if it's wrong, shouldn't it be correct on a relative basis? why isn't this number climbing?

heathrow83829··on Amazon cuts 16k jobs
you always hear about a stream of layoffs but It doesn't give the full picture. what i'm more interested in is what is their total employee count over time. that represents the net hiring net lay offs, is what counts at the end of the day
heathrow83829··on Swedish Alecta has sold off an estimated $8B of US Treasury Bonds
i've wondered this myself. I thought that everyone was selling bonds and just buying equities, gold and bitcoin. isn't that only game plan? bonds aren't investible anymore for anything more than 5 year time horizon.
heathrow83829··on Nvidia Stock Crash Prediction
but they're expected to have 8 or 9 aircraft carriers by 2035, doesn't it make sense to wait until then?
heathrow83829··on The Target forensics lab (2024)
i'm surprised by this because it's so hard to sell used goods. i have an old suit from graduation that's in perfect condition and looks quite nice. the thing will NOT sell, not even for 10$, at all even though it's practically brand new.
heathrow83829··on Tell HN: I write and ship code ~20–50x faster than I did 5 years ago
>> Ideally, codebases would grow by adding data (e.g. a json describing endpoints, UIs, etc), not repetitive code.

Be very careful with this approach. there are many ways it can go completely wrong. i've seen a codebase like this and it was a disaster to debug. because you can't set breakpoints in data. it was a disaster.

It may not look compact or elegant but I'd rather see debuggable and comprehensible boiler point even if it's repetitive rather than a mess

heathrow83829··on AI Isn't Just Spying on You. It's Tricking You into Spending More
i think the whole "personalised advertising" thing is way oversold and more for the benefit of a sales pitch for the advertisers but reality is far from it. google makes their money on volume, not accuracy. and so all the "information" they collect, doesn't seem to translate into more targetted advertisement.
heathrow83829··on AI Isn't Just Spying on You. It's Tricking You into Spending More
if you draw a venn diagram of all the stuff i get advertised on and all the stuff I actually buy, the two circles are in completely different locations with virtually no overlap whatsoever. the only time i get ads that are even remotely related to my purchases, are only ads that come after I've made the purchase and am done. personally, i don't see how they make any profit off me whatsoever.
heathrow83829··on Australia begins enforcing world-first teen social media ban
it does help. i think this is a good step in the right direction.

but there's still a lot of stuff that only parents can do. for example, screentime in the home. you can't really create a law that says no screens for anyone under the age of X because there will exceptions (movie night, homework, etc).

heathrow83829··on Australia begins enforcing world-first teen social media ban
maybe it's a step in the right direction but you can't regulate away ALL parenting. I know kids in the 5th grade getting brand new Iphone 17s! i've even seen one kid at the age of 7, getting their own Ipad. some parents even force their kids to use play on their iphone, just so they don't have to keep an eye on their kid anymore. My jaw really dropped to the floor on that one.

at some point, you just have to say that parents need to start parenting again. i'm a parent, and i can tell you it's not that bad.

How are you going to prevent kids and teens from joining everything that's bad for them online??? I think regulation is just band-aid.

the ideal solution would be to have parents say "No screens" until a certain age, unless it's supervised, or on a managed device that just lets them get their homework done.
