This is increasingly common in domestic US full-price airlines. It makes sense, in a way - most folks have their own devices, and the airlines save money and weight and don't have to worry about future tech obsolescence - but still makes me a bit sad.

Right? That's why I don't want a car with any system for entertainment, beyond generics like speakers. The car is ideally going to last 25+ years, by which time that shit will be obsolete. The software won't be upgradable, etc.

> but still makes me a bit sad.

I'm still sad the movie projectors are gone from the planes, also the little curtains for the windows, and the carve at your seat prime rib service.


I've long enjoyed both Alaska's and Southwest's version of this.

The thing I really wish domestic airlines would take away is reclining seats in economy. Nothing good comes from having them.

Same. I most recently flew Frontier and despite looking really spartan, it was actually super comfortable. And no reclining to fret over the whole flight.

Most budget carriers are going this way.

Indeed - I don't generally fly on US low cost carriers, but regularly used to fly on EasyJet in Europe, and the non-reclining seats were just more pleasant for everyone.

Thank you for this careful comment.


I appreciate the nod to whole milk, which has been repeatedly shown to be associated with _lower_ obesity in children. E.g. https://pubmed.ncbi.nlm.nih.gov/31851302/, many other studies.

This is for children and adolescents, which have different needs than the average adult. It's also just a meta analysis of literature with zero RCTs and a suggestive correlation. Unfortunately, these new guidelines don't seem even nearly detailed enough to cover these kinds of differences. The usual guidelines are well over 150 pages.

What other sources do you have besides that one observational study?

This is a meta-analysis of 28 studies. "Of 5862 reports identified by the search, 28 met the inclusion criteria: 20 were cross-sectional and 8 were prospective cohort."

No RCTs and it isn't clear that the studies were even focused on milk as a contributor to obesity, so they could be highly susceptible to confounders.

I appreciate the nod to whole milk because 'lite' milk is, well, Nick Offerman said it best as Ron from Parks and Recreation:

"There's only one thing I hate more than lying: Skim milk. Which is water that's lying about being milk"


You know that character is a joke, right?

Yeah, but that particular line rings true for me because I've used similar hyperbole when describing lite milk in comparison to real / whole milk.

If you can't tell the difference, then it's been a long time since you've had whole milk.


I recommend Dan’s book (https://danwang.co/breakneck/) to those wanting to better understand China - and the United States.

One of the best books I read this year. I think a lot of HN readers will like it. A really balanced take on China that also digs deep into the perennial question of “why can’t we build big infrastructure projects in the US?” that comes up here quite often.

We used to build those infrastructure projects.

Well of course, and the book digs a little into the history as well, and what changed around the 1960s/70s. There is a long section on Robert Moses, for example. He draws a lot of parallels between modern China and the US in the 19th and early 20th centuries - totally different political systems, but similar “breakneck” ability to build.

+1, it's a great read.

It also defies easy summaries, but my biggest takeaways were that 1) the CCP really doesn't care about the costs any of its policies (one-child, zero COVID, etc) impose on its citizenry, and 2) that the CCP is actively preparing China for a world where it's entirely cut off from the West, because it realizes that's the price to pay for invading Taiwan.


I'd agree that China is preparing to be cut off, but it's not because of Taiwan. Dan specifically mentions this:

"In vain do I protest that there are historical and geopolitical reasons motivating the desire, that chip fabs cannot be violently seized, and anyway that Beijing has coveted Taiwan for approximately seven decades before people were talking about AI."

Consider the historical timeline: "Fortress China" policies coincide with the rise of American protectionism on both sides of the aisle and the introduction of chip restrictions and punishing tariffs. Taiwan is an emotional/nationalist issue for China, but it's only one part of their policy, not the lynchpin as your comment suggests.


+1 biggest takeaway from me was that China / Asian societies emphasize process knowledge, which does not seem to be the case for U.S. tech in my working experience.

The author’s ideological bent against Big Tech shows through most clearly in the passage on Uber:

> Uber replaced taxis by having people drive others in their own car. But what was created as "ride-sharing" was in fact a way to 1) destroy competition and 2) make a shittier service while people producing the work were paid less and lost labour rights

There are valid complaints about Uber, but most people consider it a materially better service than taxis most of the time. They vote that way with their wallets, long after VC subsidies ended, and often even when it costs _more_ than a taxi.


There are several takes looking at this comparison. Here's a representative one: https://nationalcentreforai.jiscinvolve.org/wp/2025/05/02/ar...


This article compares a single ChatGPT query against 1h of video streaming. Not apple to apple comparison if you ask me.

Using Claude Code during an hour would be more realistic if they really wanted to compare with video streaming. The reality is far less appealing.


Consider how many folks use Claude Code for an hour vs. streaming many hours. Globally, not among HN readers.


My bad, in the context of the article you are definitely right.

I think I was biased by the fact that this argument was used in an HN comment where people tend to be heavy users of LLM based agents.


This is a great approach and article, I recommend it to those who asked me for sources


The biography of the author is interesting and relevant, but hardly all that matters about this or any other writing.


Yes… but more often something like laser-sintered metal printing, which is not going to melt when hot.


Yep, and it works even in the SpaceX Raptor engine.


We unfortunate know very little about how dementia / Alzheimer's develop in the first place.
