You are a brilliant woman of many talents, Margot Robbie!

It's amazing for a "standard" that there can be so many non-standard ways to do it. Your explanation is great and just reminded me that cable tester tools are a really good idea to have at home. There was one in Kickstarter earlier this year, I think, that was a really smart idea. I don't recall what it was nqmed though. Maybe you have heard of it? I'll see if I can find it.

Regardless, there are some devices that really need a specific type of usb-c cable to function properly and/or not burn the circuitry. (i.e. Nintendo Switch, the original release model (though, they may have fixed it in later hardware revisions))

Edit: Found it! That cable tester that I was referring to was called the BLE CaberQU. I think it is a really neat idea.

I'm glad someone is smart cause I sure ain't

It's a great explanation. However you have some pretty egregious use of commas that made it a lot more confusing. I had to read it over multiple times to fully understand.

It may seem like nitpicking but these subtle issues end up making it harder to comprehend and overall results in more time and effort for everyone you're trying to inform.

I have this cable: https://www.spigen.com/products/arcwire-usb-c-to-usb-c-cable-pb2202

It's 2 meters long, 240 watts and supports Thunderbolt 4/USB 4 (40 gbps).

I couldn't test the 240 watts charging as I don't have any device pulling more than 100 watts, but the Thunderbolt 4 part definitely works.

Apple sells a 3 meter Thunderbolt 4 cable (albeit limited to 100 watts of power) that isn't optical either (I think there's some special circuitry in the plugs though).

Almost none so not zero?

So a standard cable needs to be chipped to show its rating to the device, its not that the device can pull what it wants or can get, but the cable itself tells it what it can supply. Extension cables can’t do that, because it doesn’t know what it’s plugged into, and that would be if they even bothered to put a chip in. They instead piggy back off the chip for the main cable. The problem comes when you you have a 240 watt cable hooked up to a cheap 120 watt cable, with the device being told it can push 240, and starts to super heat the extension cable

This is what AI says about this video:

The video is about the dangers of using USB-C extension cords. The narrator explains that USB-C extension cords are not officially certified by the USB Implementers Forum, which means that they are not guaranteed to be safe or reliable. He also explains that USB-C extension cords can be dangerous because they can overload the power supply of the device that they are connected to. This can cause the device to overheat and even catch fire. The narrator recommends that people avoid using USB-C extension cords altogether. Here are some of the specific dangers of using USB-C extension cords:

• They can overload the power supply of the device that they are connected to.
• They can cause the device to overheat and even catch fire.
• They can degrade the performance of the device.
• They can be unreliable.

The narrator also explains that some USB-C extension cords have a label that says "USB 2.0 low speed devices can only work with one side of the ultra high rate extension cables interface." This means that the USB 2.0 connection is only available on one side of the cable. This can be a problem if you need to connect a USB 2.0 device to the cable.

The narrator recommends that people avoid using USB-C extension cords altogether. If you must use one, he recommends that you use a high-quality cable from a reputable manufacturer. You should also make sure that the cable is rated for the power requirements of the device that you are connecting to it. Overall, this video is a helpful resource for anyone who is considering using a USB-C extension cord. It provides important information about the dangers of using these cables and how to avoid them.

Per the video, the usb-c connector on the cable has a chip that communicates the maximum current that it can safely pass. By plugging it into a lesser rated usb extension cable, that assertion is now wrong, potentially dangerously wrong if enough current is sent that the wires in the extension overheat.

That's not an extension cable, but an adapter, thus it's not a problem in this case. It's a cable that can convert the data from an audio jack to something that can go through USB-C, not a cable that simply extends a USB-C cable. The cable can almost certainly handle any amount of power and data that an audio jack would pass through it, no problem, even if it were a USB-C to USB-C extension cable, and not an adapter.

The problem arises when someone tries using a higher-spec USB-C cable with a lower-spec USB-C extension cable, such as using a 240W charger with the lower-spec USB-C extension cable in the middle that can only do 120W. In that case, it would pass more electricity through than the lower-spec cable could handle, and it would overheat.

The amount of data and power from an audio jack is simply too small to overwhelm practically any USB-C cable or adapter that exists, thus it's not an issue.
