40gbps is an insane data rate that requires shielding, precision, and testing. There is no way you are getting that for $2. That said, outside of connecting a laptop to your monitor, you don't need a 40gbps cable.
> 40gbps is an insane data rate that requires shielding, precision, and testing. There is no way you are getting that for $2. I dunno, Cat8 is 40gbps and pretty cheap. DOCSIS 4.0 does 10Gbps on some really ancient cables. I'm sure Cat9 will do even better, at least the cat people and the doc people are trying harder than the USB people. Unifi even has a PoE-over-coax solution. Add some Anker GaN shit and I'm sure it…
Is it really though? People are selling cables, but 40Gbase-T hardware does not exist, and 10Gbase-T hardware is already crazy power hungry and the SFP+s heat up much you burn yourself if you touch them. Meanwhile USB-C 10 Gbps works on an iPhone.
Meanwhile, Coax is huge and stiff. Good high-speed USB-C cables actually have mini coax inside.
I don't like USB-C because they all look the same on the outside, but they're not all the same on the inside. Especially my cheap consumer electronics. Sometimes they will charge, sometimes they won't charge, but all the cables look the same, and you don't tend to know in advance.
This is an acceptable failure mode. I'd be nice if there was a standardized LED flash or color that you could get so if your relative said something isn't working, you could ask, "Is it flashing three times?" or whatever. The alternative is barrel connectors. If you plug in the wrong one, there's a decent chance that it a) won't work, or b) never work again.
I remember my parents had a D-Link ADSL modem and a D-Link router. They even stacked onto of each other with rubber feet! They had identical-looking power bricks, with the same barrel plug.
They were different voltages!

Yeah maybe USB-D will get it right. But probably not. I had such high hopes for USB-C. Now I keep a couple USB-C to USB-A adapters lying around to force the charger (which is just a normal home outlet with a couple built-in USB-C ports) to speak old school USB-A charging instead of trying to negotiate PD with a shitty device that did not implement USB-C correctly. Yes that's the fault of the manufacturer. But the wil…
Unfortunately the EU has written USB-C into law, so there will never be a USB-D. I guess we should be glad they didn’t do this 30 years ago, or we’d still be using PS/2 connectors.
I love traveling with this Anker 160W charger, which has 3 USB-C ports.[0] I just found out about GaN technology last year and I can't believe it isn't more widespread. This one can charge two MacBook Pros and an iPhone at full speed. [0] https://www.anker.com/products/a2687-anker-prime-charger-160...

Yep. The two fucking resistors. All it takes 2 x 5.1K, and yet, somehow, people keep fucking it up. It's not expensive or complex. It's just that somehow, no one thought to look up "how to add type c to your device" online, or ask an LLM, or put literally any effort into making sure the device works as it should.
Those two resistors cost money. It's not incompetence. It's a deliberate choice.
Even over on r/usbchardware it is super common for people to conflate "PD" with this missing resistor issue. Part of the confusion is that the devices that people want to charge with are very likely to be PD power supplies.

You're saving a fraction of a cent per device, while banking on customers not sending it back as defective because it didn't charge when they tried it with a random cable. If it is a deliberate choice, it's a really, really dumb one.

I agree. Lightning is such a better connector and one of the main reasons I still haven't replaced my phone. If lightning could've just been updated for higher bitrates it would have been so much better.
I went through lightning cables fast. Unsure why, maybe I sweat a lot, or keep my phone in humid places. But every so many months I had to replace the cable because the 4th pin would be burned. I don't have that issue with USB-C. But I do feel that the lightning receiver is less fragile over the USB-C one. Removing lint from a USB-C receiver is harder.
I think my only big complaint with USB C these days is that the sockets wear out quickly. The charging port on my motorola phone got so loose that I frequently end up with an uncharged phone after a full night of "charging", just because the cable's own weight keeps yanking it out of the phone. The phone is not even 3 years old. It would be nice to get a user replaceable USB port. Meanwhile, I'm not sure if those mag…
