hey, fwiw, I don’t regret your raising it, and I appreciate that you’ve been engaging with me :)

I would love for this thread to accomplish something other than meta rifraff, so — I’ve never worked as an Apple Store floor sales person, but:

> In the 90's, a USB cable was just four braided wires – literal copper wires which link copper pins in your [computer] with your [printer]. Two of them carried the data, and the other carried power and ground. This worked, and it was an affordable, easy-to-implement standard which spread like dandelion seeds on the wind.

> Now in the 2020's, we have USB-C. Have you ever had a kind of “friend” who tries to be “everything to everyone“? Well, that‘s USB-C.

> We fixed some things with USB A and mini – er, micro – B, like how hard they were to plug in, and how you invariably seemed to find yourself holding them upside down more than 50% of the time!

> And, well, engineers being engineers, and USB standing for universal serial bus, we tried to also solve all other problems at the same time. Like you couldn’t use a USB cable for video, or to power an air fryer.

> So, these days, USB cables are more than braids of copper wire. They are “active” cables! meaning they have a microchip inside. Even our cables became little computers.

> And we kept backwards compatibility with USB, so that if you use a plug adapter, you can take an original 90’s USB mouse and plug it right into your brand new iPhone n±1!

> Or nowadays, you might grab the wrong cable in your kitchen, and plug your toaster oven into your iPhone. yikes! I know you came in to the store today with a simple-seeming question, and we’ve been standing here now for minutes, and I apologize – but now I hope I can answer your question about why this cable isn’t recognized by your new phone.

> When an active cable is plugged in, the chip inside the cable “negotiates” with the chip inside the device. For a device you hold in your hand and use without thinking about it, like your phone, we have made the negotiator more stringent than we did in our tablet. :)

I love USB-C. Its awesome with one cable I'm able to plug in multiple different models of computer to my monitor and get 3440x1440 160Hz + multiple USB 3.0 + audio + 65W power. Or go to my desk at work and plug into my dock and get multi monitors + gig networking + multiple USB ports + audio + 90W power. I'll take that over proprietary dock connectors any day.

I love that the same power adapter I use to charge one computer works with all my computers, my portable game console, my headphones, my portable speaker, my phone, my tablet, my flashlight, my battery bank, and more. I like that the USB-C port in my car can natively charge my laptop, at least when asleep/powered off, without needing an AC inverter to run a 19V brick.

There's no way you're going to convince me my life with dozens different sizes of barrel power adapters with different voltages/polarizations, micro + mini USB, and more proprietary power connectors were better. You're never going to convince me having the vendor lock-in of proprietary laptop docks was better than just a single cable to do it all. I can't wait to retire my last few barrel-type power devices.

> than just a single cable to do it all

Well, generally speaking, you can't use "just a single cable". Because a USB-C cable only carrying a power charge would still technically be a USB-C cable. And you would never know until you tried to connect your display with it
