I also thought flights were a compelling use case until I saw that the battery life was “up to” a whopping 2 hours


Aside from the in-seat power, I think another likely solution will be third parties like Belkin making a less "apple-esque" but longer lasting battery that's compatible with the magnetic connector. The OEM solution looks quite small as is. [1]

Interesting, it doesn't show a way to charge that brick. I assumed it would have USB-C for charging, though perhaps MagSafe makes more sense given the propensity of the user to stand up and start walking without realizing he's plugged into the wall!

I also wonder if it will use the other type of MagSafe (like on the iPhone) charging. I could see the argument for convenience, but presumably this would be significantly slower charging than over USB-C.


The real-world photos of the demo units show a USB-C port next to the cable.


Or the 10,000 battery bricks that have existed for 10 years.


Unless it's plugged in, in which case it can be used indefinitely. Many planes today allow you to plug in devices from your seat.


Many also do not. Maybe even most?


I typically fly one airline so it could just be their planes, but I don't remember the last plane I was on that didn't have outlets[1]. And certainly the folks that can drop $3,500 on this are more likely to either be in business class or flying "nicer" airlines, so plug access feels like a non-issue to me.

[1] That being said, the number of times a plug has been able to support a charging brick directly is...miniscule. They're usually so worn out that they can't support the weight, so I have to carry the extension just for that reason.


Then you get to use it for 2 hours. Most domestic flights only have two hours or so of time when you're allowed to use your laptop.


Usually very limited amperage, almost certainly insufficient to keep this thing going indefinitely.


This is not true. Most seats have a 120/240v receptacle that can keep laptops charged while in use.

You’re forgetting this thing uses a mostly passive M2 chip. Not to mention I’m sure they designed it so it could be powered from the USB c ports on their laptops. The headset won’t use anywhere near the amount of power you seem to be implying.


That's voltage, not amperage. Just because it's a 120V receptacle doesn't mean you can draw large current. My laptop charger gets booted off the grid pretty frequently on a full plane.


Even if it's limited to 1A, 1A/120V must be enough. It can't have loud fan so must be power efficient.


I wouldn’t assume you can draw 1A.


Two extra batteries will likely be trivial cost in the context of a $3500 device, not sure why this isn't clear to everyone critiquing the battery life?


I'm assuming 3rd parties (like Anker, Belkin, etc) will be producing batteries for this not long after it's launched that will run much larger. If we assume the Apple battery for 2 hours is something like 40Wh, a 100Wh battery (the TSA max I believe) will give you 5 hours (enough for approximately 2-3 movies), which seems like plenty.


i can certainly see the appeal of a VR headset on flights, but if that's all i'm buying it for why would i go for a $3500 apple device instead of a $299 headset from meta?

can i even use noise-cancelling headphones with the reality pro, or is it locked to the built-in spacial audio headest? because i'd rather block out the noise than the peripheral vision on a plane.


a) Meta Quest is heavier, bulkier with significantly poorer quality displays.

b) You can use any earphones you like. There are videos of people using the AirPods Pro which are the best noise cancelling IEMs on the market today.

It's also made by Facebook. We tend to underestimate the power of brands in tech. There are few places I've seen as loud of a status-signaling system than commercial aviation.


The screens are totally different, as are the apps.


on a flight you just plug it into your seat


For starters, one of the ones mentioned in the article…


There was blog post on HN recently about the upbringings of great scientists, physicists, polymaths, etc. They almost invariably had access to near unlimited time with high quality tutors. He cited a source that claimed modern students who had access to significant tutoring resources were very likely to be at the top of their class.

Personalized learning is highly effective. I think your idea is an exciting one indeed.


""AI"" conversations count for very little in the way of getting genuine understanding. The last two decades have made the intelligentsia of the planet brittle and myopic. The economy's been a dumpster fire, running on fumes with everyone addicted to glowing rectangles. If we put an entire generation in front of an """AI""" as pupils, it'll lead to even worse outcomes in the future.

I doubt the 2 Sigma effect applies to ""AI"".

The panic about this new tech is from how people that leveraged their intelligence now need to look at and understand the other side of the distribution.


Currently revising for master exams. Conversations with ChatGPT have been a game changer for enhancing my learning.


But how much of what it said was nonsense? And did you spot the nonsense or accept it?


Seems like great training for hard sciences, where spotting nonsense or mistakes is a desirable skill.

May also be useful to “bullshit” disciplines? The SOKAL affair showed that some disciplines are perhaps just people doing “GPT” in their heads: https://en.m.wikipedia.org/wiki/Sokal_affair Edit: this one is hilarious: https://www.skeptic.com/reading_room/conceptual-penis-social...


Yeah it is a mixed bag. Like others have mentioned, because it doesn't say when it's unsure of something I wouldn't trust it as my sole tutor. But for a subject you know it can help you connect the dots and consolidate learning.


The % of nonsense is constantly going down as these models get better, though. Even if what you say is a problem now, it won't be a problem for long.


That's not necessarily true. As the percentage of nonsense goes down there is a critical region where people will start to trust it implicitly without further verification. This can - and likely will - lead to serious problems which will occur downstream from where these unverified errors have been injected into the set of 'facts' that underpin decisions. As long as the percentage of nonsense is high enough an effort will be made to ensure that what comes out of the system as a whole is accurate. But once the percentage drops below a certain threshold the verification step will be seen as useless and will likely be optimized away. If the decision is a critical one then it may have serious consequences.

You see something similar with self driving vehicles, and for much the same reasons.


Does avoiding AI allow one to avoid nonsense?



Five nights a week is extremely frequent, if she does not tone it down she will likely develop moderate to severe bladder problems in the future.


There is some promise with NAC and the bladder nightmare that can happen, but yes agreed, those bladder problems can be heinous, and accepting a mildly reduced efficacy in the short term for the trade of being able to maintain this longer term is the risk argument that I think I'd be making here. <3 :))))


In my personal experience marijuana only makes depression worse. It can make it more bearable in the moment and treat minor anhedonia, but at least for me it only bolsters my unhealthy habits which in turn makes the depression worse. I don't think there's any evidence that it can lead to long term remission. It's the neuroplasticity provided by psilocybin and ketamine that really helps.

I think psilocybin is promising, but doing it when you're depressed can put you in terrifyingly bad places. I think in the long term psilocybin and ketamine will both end up being valuable tools in combating treatment resistant depression. My guess would be that psilocybin will be used more in clinical settings with a guide and ketamine will be something you can do at home and talk about with a therapist later.


How often were you taking it? I use ketamine for depression and I don't think I've experienced tolerance before. While I usually feel less depressed during the high, I don't feel the long term anti-depressant effects for 2-7 days after treatment. Once it comes, it lasts for 3-6 weeks. It makes me a completely different person. I can go from borderline suicidal to living in the moment and relishing the simplest parts of life in an unbelievably short time. I fully realize that depression is more than just neurochemistry and that its just as important to use these windows of joy to create healthy physical, mental, and social habits to prolong wellness. I'm still figuring out how I can create a long term regiment using ketamine, but for the time being it seems like using it once every month-ish is making me feel well enough and is not leading to tolerance or addiction. This is after over a decade of constant crippling depression. If I were you I would definitely not think about it as a "feel better in the moment drug", that will only lead to overuse and potential psychological addiction. I was briefly prescribed anti-anxiety medication I can tell you that having a pill that instantly stops chronic symptoms is unbelievably addictive. Ketamine is different in that the effects can last longer than the high itself when used correctly. It takes time, research, experimentation, and understanding of contemporary ketamine assisted therapy methods to really figure out what works for you. I wholly believe that this is going to replace the majority of antidepressant use in the next twenty years.


The ramp-up to "I need to save this for extreme circumstances only" happened over about a couple months, during which I'd use it maybe once or twice a week. I didn't feel any particular longer-term boost attributable to it; it felt very much like just an acute treatment. Maybe I'm due for more experimentation, I'll keep your comment in mind the next time I'm anxious and feel like giving it a another try. Regardless, thanks for your comment.


It's different for everyone, it may be that it works better for my neurochemistry that it does for yours. And for what its worth its never really helped my anxiety, only the depression. You can also try doing it in a more clinical setting with a therapist, that makes a big difference for some people. It can allow you to work on deep-seated emotional issues in a very profound way.


The implication is that additional perks will make other stores less likely to unionize. One store successfully unionizing is certainly enough to cause Apple to take such measures, they're likely trying to prevent a domino effect.


A company of Apple’s size routinely adds and removes employee benefits. It’s not like they offered nothing before a single union consisting of a handful of employees showed up. To make this claim you need to look at a time span way longer than a couple of months to see if there’s an actual correlation.
