The USB4 protocol can handle 160Gb/s split asymettrically (so, say, 120Gb/s out, 40Gb/s in), wheras the upper limit for DisplayPort’s highest bandwidth mode, Quad UHBR 20, is 80Gb/s in one direction. So you can saturate your DisplayPort 2.0 quad-channel with more than enough bandwidth to power three 10K 60Hz 30-bit (i.e. very high-end) monitors in DSC mode, and still only be using half the bandwidth of USB4, all using a single cable which I can also use to charge my earphones.
Uhm no? There are more than a few use cases that require a mobile set up for demos for example but that you’d also want to use in a desk setting. For example, architects or sw dev.
Which is still enough for almost all sane use cases.
Like 2 4k60 monitors and literally nothing else? You have a very conservative opinion of what a “sane” use case is. Not to mention that lots of USB-C cable certification is a mess so not even getting the cable is simple (or cheap).
K then buddy. Keep buying dongles for your dongles.
My point is that including the ports is extremely simple. I’m not telling you that it’s wrong to choose to use a dock because you find it more convenient. I’m just saying that you could have the option instead of that being the only option you have. There’s no technical reason to not include the actual physical separate ports.
Also, monitors and your earbuds? That’s a very low bar. Lots of different tasks would require far more than that. Devices should be flexible.
Agreed. It’s a pity, then, that no-one has invented a single port that can replace USB-A, DisplayPort, HDMI, propriatary power connectors, Thunderb… oh… wait…
Yeah, show me a laptop that has 10 of those. Plus, your conveniently ignoring the plethora of adapters you’d have to use if all you had were USB-C ports.

Most devices only have 40gbps USB4. Which is still enough for almost all sane use cases. Frankly, if you need multiple 4K monitors get a desktop.
