USB 4 will be a failure

[SS451]

More so for PC and desktop computing. It doesn't offer anything compelling to enthusiast and if it does weather or not your thunderbolt 4 devices supports it is questionable and if it does you have to pay a huge mark up

I was trying to think of a use case. My idea was for small portable monitors so you could have one cable for power and one for video

 

but I guess that works to

The problem with USB 4 is it suffers all the same problems of USB 3, half of its features are "optional".

So inherently a USB 4 port can be nothing more than USB 3.2 Gen 2x2, or may support power delivery, displayport, thunderbolt, etc.

 

Its infuriating as USB was invented as a simple, fast, and importantly highly compatible replacement for our legacy ports, and its turned into the complete opposite.

How so, for how long TB exists it's more of a failure in my eyes following this logic. Really USB4 is same thing but not bound by licensing nonsense and cheaper to implement.

USB4 is still kinda newer, but blame everyone being slow adolting it, even Type C in general. It's also not brand limited, can act as DP and TB it's just that doesn't mandate higher feature set. 

There are ports of it on motherboards, can use fast SSD with these enclosures now. Still can charge very fast, be used as DP and such. 

Can power and signal monitor with 1 cable.

Adoption needs to take off that's it. Chicken and egg problem, peripheral companies slack, just lately making use of Type C but then still mobo using older port mostly. So everyone waiting others to start that nobody switches to new standard. At least Apple only uses Type C now.

Type C for most of its history was REALLY expensive to implement. the cable connectors until 5 years ago were all hand made, not automated. 

USB4 will have similar problems in that timing and routing is a pain in the ass. Even with AI automation.

Initially everything needs to start slow before ramping up for mass production. But it's been so many years and we still see more old connector on boards though. For years many refused to change. Now we're here finally with more peripherals etc. using it. But on many still only on one side, motherboards still slacking. We're far from initial release, price is not a factor at all. Talking about just the Type-C connector.

As for USB4 feature-set that too, is crawling to gain traction. Initial motherboards costed so much just to get one port with it. Lately finally we're seeing more boards offer it, still a premium though. But fair enough, not every port is going to be fully featured.

Hot take: All mid-tier and higher motherboards should have Thunderbolt 3+, USB 4 support, and multi-gigabit Ethernet. Apple manages to sell a $599 full machine with Thunderbolt 4 support and USB 4, so the cost of implementation isn’t really an argument against it anymore.
