I saw a curious post recently that explored this idea, and showed that it isn’t really the case. The internal layers of the model aren’t really reasoning in English, or in any human language.
Translation in/out of human languages only happens at the edges of the model.
Internal layer activations for the same concept are similar regardless of language, while activations at the top/bottom layers diverge. Meanwhile the pattern is reversed for same language different content.
So we do at least agree on the fact that quality of human language <-> embeddings transition depends on how good target language is represented in the training dataset?
Even if it happens at the edge, on every conversation turn, I may assume non captured small subtleties of meaning over time can accumulate into significant error.
The issue with C++ complexity is that the standard development model is dysfunctional.
They aren’t able to bring concepts like “a file” into the standard because one standards body member maintains a compiler in some baroque ancient environment without the concept of a fs. Too much is forced to implement at the library level instead of in the compiler, and end up feeling half baked for real users (modules, coroutines etc).
It’s a self fulfilling prophecy. You can see these exact same market dynamics at work in the mobile telco industry. Newer online only upstarts able to save on costs because they don’t operate a retail store you can visit to get help resetting your email password.
It’s always amazing going to these stores and seeing the support they provide for frequent “how do I computer?” questions. To me, this is like going to the water department because you need a new faucet on the kitchen sink. We make no such distinctions about who fixes what for purveyors of Internet services though.
One time, I needed this. I lost my phone with a physical SIM card and needed a replacement that day. Now I'm trying to remember the eSIM transfer flow to know if this is still an issue.
But also, which MVNO should you go to? Carriers supposedly prioritize their own customers, so it feels a bit like running on spot instances.
> Carriers supposedly prioritize their own customers
They explicitly do, even among their own customers and plans. If you Google the carrier name plus QCI, you’ll find tables where people have documented, which plans are in which priority group
I've also seen MVNOs be denied frequency bands or cells that were in the highest demand, leading to worse connectivity despite being on the same network.
> But also, which MVNO should you go to? Carriers supposedly prioritize their own customers, so it feels a bit like running on spot instances.
If you are so paranoid, just get multiple SIMs? Most phones support that these days, especially multiple eSIM. And the plans are really cheap (at least where I live).
Mint (T-Mobile MVNO) has been great for me, $20/month/line and my one experience with international travel was good ($20 for 10 days). I used to be on Verizon and the quality of service doesn’t seem any worse while the price is dramatically lower.
Mint works well until it doesn't. I travel a lot and use voice over ip(VoIP). One day I called and got an automated message that my account needed funds. It didn't, my annual payment was months away.
My call to tech support was the generic worst. He insisted there was trouble with my current cell tower and I should reboot my phone. (ignoring the fact that I was able to get automated message). I explained I was using voice over ip, but the tech support didn't seem to understand that technology. Perhaps it wasn't in the script. I was on the call for about 30 minutes and eventually gave up. Phone started working about eight hours later.
Previous issue was with their roaming in foreign countries, however with VoIP that hasn't been an issue for years. So, a couple problems in about eight years. I rank them as one of the best among the terrible options.
Insisting on saying VoIP to the Mint rep instead of WiFi Calling (the term used by Apple, Google, Mint, and practically everyone else) is asking for a bad time.
US Mobile gets you QCI8 (same priority as Verizon postpaid) when you're on the Verizon network with a 5G device, and they let you pay for QCI8 on AT&T.
USM is the only MVNO I've seen that actually advertises QCI tiers. I had to look the term up when I was initially considering them, as I'd never even encountered it before. It was a major factor in finally feeling confident I wouldn't be giving up too much by leaving AT&T.
eSIM transfers are an absolute nightmare on T-Mobile. I recently did two of them and both times, the transfer started but never finished, so I ended up with no service on either device. That means no ability to call their support line and no ability to receive the confirmation SMS they use to verify you are the correct person. They also immediately permanently nuke your physical SIM card so the only way to go back to sanity is to purchase another $10 physical sim card or get one of the physical sim cards that you load eSIMs onto (I did the latter so it won't self-destruct every time I do a transfer).
1. They only do transfers through their native app, not on their website. To log in to their native app, they will do SMS verification. So I sure hope you are still logged in before they lose your eSIM and leave you with no service at all.
2. If you are able to get into their native app so you can access their tech support, their AI chatbot will flat-out lie to you and tell you that T-Mobile cannot send you a QR code to download your eSIM (even though T-Mobile's own website states that they can). If you ask politely for a human, it will resist. I've found "connect me to a human you worthless fucking bot" is the secret passcode to get a real human.
3. If you request they send you a QR code, some of their support staff will ignore that request and still try to initiate the transfer through their app, so clearly requesting the QR code is not a common procedure.
4. When you request a QR code, even though you provide the EID, they will ask for an IMEI number. They then generate the QR code for whatever EID they have associated with your IMEI number in their database, completely ignoring the EID number you sent them. They did this to me _three_ times. The only way I managed to break the cycle was I sent them an IMEI number for a phone that was never on their network so they'd finally listen to me when I told them my EID number.
I'm never buying a phone without a physical sim card slot again. There's nothing wrong with the eSIM technology but the carriers have decided to make it as miserable as possible. The hardest part about transferring a physical SIM is finding a paperclip.
As a counterpoint (not sure if this was t-mobile, apple, or both), I just upgraded from an iPhone 11 with physical sim, to iPhone 17 with esim.
All I had to do was hold the new phone next to the old one, and it just transferred the line over and deactivated the old sim automatically. I wasn't even in the US (so not even on their network), and it was stupidly seamless.
It sounds like t-mobile support has gone downhill. Last time I had to contact support was 2020, and it was really easy back then. I rarely had to wait more than 5 minutes to get a human, and I once had an issue escalated to the "executive resolutions" team and resolved to my satisfaction the day it was opened.
Apple’s system mostly works. If you need to reissue an esim without being able to transfer from an existing device on T-Mobile though need to either call in and give imei or get past the chatbot and there’s a page text support can give you to enter details. I was never able to successfully use the shit t-life app’s manage esim option.
You were on the happy path. I just had to get involved for a family member that broke their Apple phone and couldn't get their SIM transferred. Even after adding them as an authorized user under duress, they had to physically go to a T-Mobile store to get their phone on the network.
> When you request a QR code, even though you provide the EID, they will ask for an IMEI number.
Everything else you say is accurate but they do not require this, T-Mobile is the only major in the US that doesn’t match EID to IMEI. I know because I use a removable esim (esim.me) euicc with multiple phones. I have to read the super long eid off to support to activate it. I cannot activate service on this card with verizon or at&t as its eid doesn’t match to an imei for them.
I think you're misunderstanding. I'm not saying T-Mobile locks the EID and IMEI together. I'm saying their tech support will completely ignore any EID you send them and instead look up an EID in their database based on the IMEI you send them. If you manage to convince the tech support to actually listen to you and use the correct EID then yes, everything will work out fine and you'll be able to move the card across devices.
I was also using a removable esim (from jmp.chat) and they did this to me three times. Each time it went like this:
> Me: Please send me a QR code to download my esim. My EID is XXXXXXXX
> Them: Thanks for providing your EID, please send me your IMEI (the first time this was just a plain message, the 2nd and 3rd time they sent me a link to a form to submit my IMEI to them)
> Me: <sends them my IMEI>
<at this point, the first two representatives initiated a transfer through their app and told me to wait 2 hours and then the transfer would finish. I told them whatever automatic transfer they just initiated will not work and they _need_ to send me the QR code.>
> Them: What is your e-mail address
> Me: My e-mail address is XXXXX@XXXX.XXXX
and then they'd send me a QR code. I'd then attempt to download it to my jmp.chat esim and I'd get an error that the EID was incorrect. Then, I'd try using the QR code to activate the built-in eSIM on the phone with the IMEI that I sent them, and it would work, proving that they were looking up the EID for the IMEI that I sent them rather than paying attention to the EID that I started the chat with.
The 4th and final time, I sent them my Librem 5's IMEI which had never been on T-Mobile and does not support eSIM. They told me that the phone was carrier locked, I assured them it wasn't and explicitly told them "it is important the QR code is for the EID I provided you. The past representatives have ignored that, leading to the error message <pasted the error from EasyLPAC's logs that was something like EID is incorrect>". THAT time they finally listened and sent a QR code for the correct EID, which let me download the eSIM to my jmp.chat card. At that point I was able to move the card across devices without issue.
Apologies on getting back late but… I’ve never had that experience. Historically I would call during day and get someone stateside. They would ask for IMEI and I would say ‘it’s not in your db but EID works’ and then they’d let me read that off, never an issue. Now I use the chat, it’s faster since they just give a portal link you drop the details to.
Call during day or you get the Philippines and they don’t understand specific requests like this as well. If you must do it at night use the chat route.
Personally switched from VZW to Google Fi. It's on TMOs network. As you can imagine, when engaging with Google's support was hilarious when there was something I needed, but overall I don't miss Verizon and pay drastically less.
Is Google Fi particularly cheap? Their normal prices seem to start at $35/month for 30GB of data which is more than Verizon's Visible plans at $25/month. (The current 50% off offer on Google Fi does seem a good deal though.)
I ended up switching to Mobile-X since I'm on wifi so much I only use a few gigs of data a month. $2/month + $1.90/GB vs Google Fi's flexible plan of $20/month + $10/GB.
My Google Fi is $20/m for connectivity and then $0.01/Mb until I hit 6Gb ($80) at which point everything after is no cost. Most of my data is on wifi, so my bill rarely goes above $25
I just buy local eSIM's online when I go abroad now. Lycamobile is usually good around Europe if you land in a country with them. Their UK and Portugal subsidiaries are £5 or €4 / month with 30-50GB in country including 12GB roaming in other European countries. Order before you go and get the eSIM QR code by email. But you must be in the appropriate country to activate.
The Google Fi plans with roaming are either $65/month (100GB) or $20/month + $10/GB. I often end up using quite a bit of data abroad.
For those of us who have crappy coverage with TMO, Verizon themselves offer a much better alternative to their postpaid service, called Visible. It's pretty hilarious how much better of an experience it is, and you are on the same network.
I haven't had any issues with tmobile coverage (that wasn't also a problem with verizon) in well over a decade now. Hell it even worked well in the dense hilly jungles of burundi. Verizon customer service was so bad before I switched I swore them off for life....
The single place I noticed verizon gets coverage and tmobile doesn't is three levels underground in a concrete parking garage.
Coverage is very specific to your situation. I've had basically no coverage on Verizon in offices in the Bay Area where T-mobile worked fine while colleagues could only get Verizon at home.
Those stores generally turn a profit eventually. A smaller company is just going to struggle to afford building out the stores and running ads to get people in the door.
Isn't that the opposite though? Having a store for the customer to get face-to-face support is sometimes necessary even those who prefer it all to be online. It acts as a stop gap to people otherwise low support customers.
The newer upstarts you mention are self selecting for customers who would do everything they can to never make a support call. They are just another form of having a 15 minute wait time because online only is it's own customer service barrier.
No. In the case of cell phone carriers, the only times in the past 10 years I have ever darkened the door of a retail store is times when the carrier was too incompetent to let me get my problem solved another way. For instance, there was a time at AT&T where if you had acquired a brand new unlocked iPhone that needs eSIM, you needed to receive a physical piece of cardboard printed with a unique QR code on it in order to activate it successfully.
I’ve been with US Mobile for years now and never once felt the need for a physical store.
There's a lot of reasons for this. One of them is that it tends to be a lot cheaper to have one building in Denver to host support people than to have many buildings in every city.
Besides that concept, they're selling telephone and data services. It makes sense to -- you know -- make use of them.
When we had a telephone issue back in the landline days, we didn't load ourselves up into the car and go to a store to get help from someone in person; we instead used the phone.
(That may have been done by using the neighbor's phone, but whatever. We still have neighbors and not all of them are dicks. And these days, we still have cell phone stores for those who can't empty the water from a boot. The days of brick and mortar cell phone sales are not, at this time, numbered.)
With sims switching to e-sim there's basically no reason to have in person support for cellular service. There's nothing they can do, outside of what they can already do online or over the phone. Like, if you go to an AT&T store with a broken e-sim they can't wave a magic wand. They'll probably just reset it on their end, like they could do over the phone.
Some people just prefer going into a physical place and talking to someone in a face to face conversation they can understand. I’ll very rarely want to sit in a phone queue just to talk to “Jason” who has a thick Filipino accent sitting in a crowded support room talking through what sounds like a a 1kbps VOIP connection. And I’m never going to text chat an AI bot for help.
Contrast that to my kid who is horrified by in person interactions and thinks that the kiosks at McDonalds were the world’s greatest recent invention.
Not to mention people with disabilities that make one form of communication the only option.
People are different and good companies try to serve them all.
The person at the store has direct contact with the broken device, this is a much shorter feedback loop than telling you what to do, having you misinterpret it, having you read back the results, and then misinterpreting them.
"Private credit" is a finance term of art. It could be misleading if you don't have context for the correct definition, but that's true of many posts on this site.
There were/are DRAM futures markets based on this hypothesis, historically they never worked very well because DRAM prices (at least for the same size/speed) have moved downwards so consistently over decades. That is until <6 months ago.
Originally OLED TVs used different sized subpixels for different colors as part of their wear management. Red wears out the fastest so it would have the largest subpixel.
