Someday an iPhone will have this speeds. For now we have to use usb 2 speeds. 
Got a tip for us?

USB4 Version 2.0 to Offer 80Gb/s Transfer Speeds

the EU better mandate it quick. Or else no one will know what their preferred connector is...
I'm a product manager, and if I suggested a version like USB 4 2.0, I'd be out of a job. Just call it 4.1 and stop confusing people. No way my boomer mom is going to be able to figure this mess out. Do I need a USB C cable or a 4 cable or a 4 2.0 cable?
Yes, I'm sure you understand completely the simplistic and ever-so-straightforward differentiations between USB 3.2 Gen 2, USB 3.2 Gen2x2, USB-C, Thunderbolt 3, Thunderbolt 4, USB4, USB4 Version 2.0 and their varying levels of throughput, Alternate Mode support, power delivery limitations, cross-compatibilities, display support, etc.
Mmost people aren't going to use or need this much bandwidth, and there are limitations on the device itself.
I am not seeing anything about cable lengths, but considering Thunderbolt active cables using copper are limited to around 2m/6ft, I would not at all be surprised if this is the same for the active copper USB4V2 cables, as well.
The up to part of the statement implies that existing passive USB4 cables will support up to 40Gb/s and for 80Gb/s, you will need to buy an active USB4V2 cable. There would be no reason to specifically reference an 80Gb/s active cable if a passive cable could handle the speed.
It's on the MacBook Airs and Pro's (the M1's). Those are USB 4, not TB (although it contains the TB spec of 40 gps).
I just broke down and bought only TB3/TB4 active cables so that way I know that I am covered regardless of what I am plugging into either end when it comes to products with a USB-C connector.
I love the posters who think people who run corporations, especially large ones, are mustache twirling predatory villains just looking to screw people over. It's such a caricature.
News flash: Most companies are not out to screw you, and the ones that are out to screw you are pretty transparent, anyway (cough, gambling, cough, alcohol, cough cough).
People are their own worst enemies--certainly not Tim Cook, et al.
That's not how I read it. The 40Gbps cables also say "up to 40Gbps." This is common CYA language because the connections are quite finicky and the speed depends on a lot of factors.
Second, there is a good reason to specifically reference an 80Gbps active cable - distance. Active cables can be much longer than passive cables while maintaining full speed. I recall with TB3/USB4, the maximum length passive cable for 40Gbps is 0.8meters, and it drops down to 20Gbps for cables up to 2meters in length. Active cables, on the other hand, can be much longer. But also, by nature of being an active cable, the chip in the cable must itself fully support the spec. So a USB4 active cable might not be forward compatible with USB4 v2 or whatever they call it - but a passive cable has no such restriction.
So wait.. We're back to calling USB 3.1 Gen 2, USB 3.2 again?
I need some of what the USB-IF is smoking, I think they got better stuff than me and Im in California!

It’s USB but v4, the revision, and it’s Type-C. Add some Thunderbolt and don’t forget to keep the cable 6ft. What’s confusing about that?
As a techie, the list here is insane and even worse for regular consumers. It allows for deceptive marketing by companies getting to make their cables seem like the newer/better ones, and is also a mouthful for no good reason.
I think the whole thing is very balkanised - naming conventions alone for USB is bonkers - you'd hope that a certified Thunderbolt 5 cable would cover all possibilities in that class and anyone needing reliable high speed cables go with those.
As for potential future connectivity, if the EU (amongst other countries) mandate USB-C as the connection standard it would certainly make iPhones interesting as cameras because users would finally be able to transfer 4k or 8k footage at speed off the phone as well as potentially charge at high speeds (at the potential risk of battery health?).
Moreover though, especially with Continuity Camera coming in Ventura, is there room for Apple to consider re-entering the camera market with an iSight camera that could then be used with an AppleTV device as Apple's own Portal?

No. It's Unified Memory all the way now, which is not possible with eGPUs!
I would expect that your Thunderbolt 3 -> 2 adapter should still continue to work.
Should be possible then (6k 10bit 120Hz)!6K 120hz displays incoming?
Also 8k+ 10bit 60Hz which would interest me more...!
If I remember correctly, the Thunderbolt mark is still owned and certified by Intel so the USB consortium has no control of the mark, but the protocol will still likely remain part of USB.
