If you want to buy a house or apartment, you're probably looking at at least several hundred thousand dollars, and average working class people would need years to save that much.

In other words, we're looking at someone with a few hundred thousand dollars, held for a few years. At which point, what's stopping them from keeping the money in an index fund, instead of under the proverbial mattress?

Also, taking a mortgage is a totally normal thing to do when buying a house, it will give you years of enjoying your home ownership, and in this case inflation actually works for you!
> judges, attorneys, police and prosecutors all work on the same team

These guys ultimately are desperately wanting a black box computer algorithm, where 1. you type in the suspect's name, 2. the algorithm spits out "guilty" and 3. that is admissible to a jury. If they had this, every single one of their jobs are a piece of cake:

A crime happens. The police can now pick up literally anyone they don't like. The prosecuting attorney doesn't have to do anything--just enter the suspect into the algorithm. The judge doesn't have to do anything. Computer Says YES. The jury doesn't have to do anything. Computer Says YES so I can convict and go home. This is the future of law enforcement. They just have to get that darn black box approved and invulnerable to defense attorneys.

Are you sure your intuition about wireless charging for EVs is correct?

Bjørn Nyland did a test of a wireless charging system vs a wired charging station, measuring at the power input to the charging station. If I remember correctly the wireless charging was actually more efficient. Now, they were clear that the wires charging station wasn’t an ideal scenario. Though I don’t remember the reason why.

The point is, wireless charging can be surprisingly efficient, and wired charging can have surprising inefficiency, to the point where the difference can be negligible in specific cases.

And I’m guessing that once the ball is rolling the efficiency of wireless charging will gradually creep up over time.

You’d think that housing would be the priority, all this other shit getting cheaper while basic necessities turn into investments.

I wonder if someone from 1950 or so would believe an average person from the future that told them almost all the work they do at a ridiculous productivity level would go to a house to live in.

Think of all the wasted opportunity of most people not being able to spend their work on other things besides basic necessities.

Yeah, I'm not sure, that's a question for someone more advanced in their practice than me! But what I was understanding Thich Nhat Hanh to be saying was that we can't just rely on what was written down because they too can contain misunderstandings. As a Baul teacher I've been lucky enough to practice with says, don't read books, but study well. [1] A few of my friends ordained with Thanissaro Bhikkhu when we were younger, so maybe I'll give them a call and see what they think!

And yeah, for sure, there are plenty of divinities and whatnot in Buddhism -- a teacher of mine was just teaching on diety yoga with us last night -- but at least the way I practice with it these days is as a way to better relate to something that goes beyond physical form.

It would be very shitty policy to "barge in with little warning". Rooms are checked regularly, but there should be quite a bit of knocking, and in the event it is deadbolted and the hotel guest refuses to open the door, or arrange a time the room can be inspected, then hotel management should be convened. Only after initial contact has been made and the hotel guest unreasonably refuses to allow access for an unreasonable period of time should hotel management "barge" in, or call the police.

Like so many other things, I see this often in the op-ed-osphere and r/teachers, but have a hard time determining how much is doomerism/alarmism, and how much is quantifiable/credible worsening. There are few topics where one can't find a slurry of opeds lamenting the erosion of the youth, the commons, and the world at large, complete with questionably narrow and nuanceless visualizations.

I am torn between two reactions:
1. This seems like a real trend but damn, so much dramatization derived mostly from anecdotes.
2. But holy crap, there sure are a lottttt of anecdotes, and they're consistent in direction and outlook.

So who are some trustworthy authorities on this topic? Where's a good place to get a neutral take (both politically and emotionally) on these trends? Who's the 538-circa-2015 of educational stats?

For HN users in the education world, is there broad consensus among your peers that this is a catastrophe? Is it recoverable? Is it reversing or improving in any areas? How's the latest cohort (eg 2nd graders) doing compared to genz at the same stage?

In other words, can someone with more context suggest how much, if at all, to be existentially worried about this?

I want to be clear, up front, that I believe credit should go where credit is due but, ignoring the arrogance of the blog post in its entirety, there are two closely-related things that rub me the wrong way about this. First is the fact that the actual famous image (which is both the image the author uses at the top of their blog post as well as the one found on wikipedia — who, ironically, _do_ indeed give them credit) is not the image this person created. Second is the fact that the author did not even create the original image. As mentioned in the blog post, the original was created by Abraham Wald. So, this person is neither the creator of the original image, nor the creator of the famous image. They simply feel like they haven't gotten enough credit for making it famous.

It is _if_ you self-host. Paying wordpress.com has been a crappy experience IMHO. You don't get much for the base tier and you don't get plugins until you pay for a much more expensive tier. I just wanted a place to blog and was tired of managing my ghost self-hosted blog and didn't want to pay for ghost. I ended up having to move up a tier to do basic things (sunk cost) and I blog probably 1-2 times a year if that. Whatever, I've paid up for a year or two now and once that expires I'll re-evaluate.
For me, it comes from the confidence that while I don't know the outcomes, I do have the ability to handle any of the possible outcome.
Why do you find this ironic? Doesn’t this follow logically: Greens don’t want new dams due to environmental impact and now dams are been dismantled due to the negative impact on the environment.
How does Apple get around that MMS limitation?

> Gold is just a random commodity affected by market supply/demand just like every other commodities (or bitcoin). Implying it's some sort of a "hard currency" or can be used to compare prices of goods/services/housing over long periods of time is just absurd.

It's sensible to use gold or housing as a measure of value - they are both extremely mature markets with a relatively constant supply/demand ratio. It's no coincidence that after 50+ years they are still the same value relatively to each other. I'd argue that using the dollar as a measure of value would be absurd, given that it's demand is relatively constant but it's supply is doubling every decade.

> That doesn't work that well when the real interest rates (i.e. after you subtract inflation) are negative or close to negative (as they were in the Eurozone between around 2012 and 2022).

The banks are playing a much longer game. While the interest rates are held low, they increase the number of people indebted to them. When they turn the interest rates back up, they get their reward. I recommend reading the short book "The Great Taking" (https://thegreattaking.com/)
Of course there's a benefit, you get more value per dollar the more you wait.

When the first androids came out I waited for the first 300€ model and bought it. Over the years I always hovered around the 200€-300€ range and kept upgrading. The last phone was 200€ and it's the best phone I've ever had.

I can get the same (even better!) value from cheaper models over time.
Obviously one can post-hoc rationalize "sensible" as whatever worked best given the circumstances that occurred.

I’m pretty sure they mean zero interest ZIRP with regard to MMT. But people forget the second part of MMT which is confiscatory in effect even if not by name, it’s still your money but you are no longer allowed to spend it until inflation comes down, by which point your money is obviously worth less than it was and that value is in effect confiscated.
I've been meaning to compare the energy produced by those dams to a similar area of solar panels. Square miles of reservoir to similar square miles of solar farm.

The Three Gorges Dam covers 419 sq miles. Produces 100 X 10^12 watt hours a year.

Internet: 1,000 megawatt-hours per year requires, on average, 2.8 acres for the solar panels.

Calc: 2.3 X 10^11 watt-hours per square mile.

100 X 10^12 wh / 2.3 X 10^11 wh/mile2 => 437 square miles.

The Chinese done goofed.

I assume you never lived under the Concorde flight path.

There will never be supersonic transport for normal people simply because the technology is unsuitable for use near people. Most people want to fly between cities and cities tend to be inhabited by people, hence the essential tension.

Supersonic flight only works for a few specific flight paths where you are flying entirely over the ocean between two coastal airports. The moment you have to fly over people those people are going to get very angry and ban you from their airspace.

> was backed by gold and later silver

It's the other way around. US switched from a bimetallic system to the gold standard in 1873.

> I'm guessing it's that the US Currency was backed by gold

Well sort of, only until 1971 (or to some extent 1933) though. So you maybe could do that if you wanted to compare the price of housing in the 1870s and 1920s, certainly not between 1970 and the 2020s.
One way I've been told to understand this is that money is actually growing at around 6%, which is to say that money growth is highly inflationary.

Of course this is way too high, so to offset this there are deflationary measures, primarily increased productivity, technological improvements etc.

The problem with this is that we end up working permanently harder and it reaches a point of unsustainability. For example, now you generally need two incomes to sustain the same lifestyle as previously, because we need more people working etc.

Other deflationary measures included the opening of the Asian labor market, and then other globalisation measures.
The issue is investment, not consumption. When deciding what to invest in, expected returns are calculated net of taxes, inflation, and risk. Capital generally flows to the investment with the highest expected net return at every risk level.

In a deflationary environment, sitting on investable cash grows risk-free and tax-free, which makes it an attractive "investment" for many category of investor instead of putting that capital to work.
You have capital gains tax on it eventually, much of that capital gains is from inflation. The only way for it not to be a wealth tax is if capital gains is indexed to inflation.
What happens when one gets laid off, disabled, changes careers, or faces some other circumstances that cause incomes to fall below what’s needed to service debt payments? That’s why living below one’s means and saving the rest is prudent.

Unfortunately high inflation penalizes savers by eroding the purchasing power of savings, and it forces all workers on a treadmill where it seems that the cost of living rises faster than many people’s ability to catch up. The only way to beat inflation it seams is to invest in assets such as real estate or stocks, but those squeezed by inflation have little to invest, and these assets are increasingly difficult to obtain due to inflation. I find being on the wrong side of inflation highly demoralizing and upsetting.

This seems bit excessive, Concorde booms were purportedly about 105-110 dB on the ground when cruising at altitude (around 60 000 ft).

I've personally only experienced sonic booms from MiG-21s. They are not painfully loud, but surely startling. They are very deep and make the windows rattle.

That happens everywhere though.

We had some tornadoes go through a few weeks ago. My house had some minor hail and 50-60 mph winds. No damage. Yet plenty of letters in the mail offering to handle getting me a new roof.

The difference is that Florida used to make it really easy to force the insurance company to pay even when nothing was wrong.
I don't think people against inflation miss this point, they just think the massive government spending needs to go (or, at the extreme, the entire government, whether they have rationalised it yet or not), not the value of poor people's cash.
Tapes currently don't really operate like tar anymore either. Filesystems like LTFS stick the metadata all in one blob somewhere.
Pretty sure they have a steady poor people target rate as well (unemployment rate roughly) so no need to worry.
Certainly not the intention. The intent is that opaque junk fees are prone to abuse this way and we have no way of really knowing that they aren’t.

Boom (and supersonic aircraft) are a strategic investment priority for Saudi Arabia to sustain demand for oil. If that doesn’t tell you everything you need to know about their impact on emissions I don’t know what else does.

> I don't want to carry 4 big bags in the train when I travel international

Japan has this really cool service where you can get your bags picked up from your hotel room and taken to the airport or from the airport to your hotel room. It costs max around $20 USD.

> I don't want to travel 30 miles if my plane get cancelled.

My local airport (Sea-tac) is almost 30 miles from Seattle. It can easily take an hour driving to get there. I do agree that taking lots of luggage onto the light rail (WHICH DOESN'T DROP YOU OFF IN THE AIRPORT!!) is a bad idea.

But I am one of those people who despises checked luggage, since it can add another 30+ minutes to checking in. Compared to carry-on and TSA pre-check, where I can walk into the airport, through security, and be at my boarding gate in under 10 minutes.

But hey, Seattle is, as much as I love it, not a world class American city. Let's try NYC.

It can take over an hour to get from midtown Manhattan to JFK driving.

It also takes over an hour on the subway.

Oops, another bad example.

You know what, I am starting to think flying out of Boston Logan[1] is pretty nice.

But seriously, if you want a huge international airport, you need a lot of land, and you don't want to put that smack dab in the middle of a city, unless the land got paid for long ago, and even then, you'll be stuck with an airport that you cannot expand.

Meanwhile a train from Tokyo to Narita Airport is under 20 minutes.

[1] I legit like flying out of Boston Logan, the big dig was expensive but wow was it effective. Also shout out to Bogota Colombia for having super clean streets around its airport. It was an amazing second impression flying in (the first impression being how beautiful the city is from the sky!)
