Re: Sure, USB-C is way more versatile
I do carry a small hub with me, but that's only if I'm going onsite.
At home, it's ONE USB-C cable in the MacBook (which has 2 on each side) which goes directly to my work screen. Through that one cable it gets power (from the screen), it hooks up to the screen itself, it drives the speakers hooked up to the screen*, it interfaces with a 2TB SSD which I use for Time Machine via one slot of the USB3 hub in the screen and talks to an rather old printer which is hooked up to the second USB3 slot in that screen. Which is 4K@60Hz of which the Macbook could drive two - AFAIK in daisy chain, still over that one stupid cable.
My old laptop needed a HDMI cable, a power cable, a 3.5mm jack, and two USB3 cables because - and this is important - one of the USB ports had stopped providing enough power. That's a lot of single points of failure, and that did indeed herald the need for replacement after 6 years: a port gave out.
In the new MacBook I have 4, so if the one I use gives out or wears too much, I still have 3 more. In addition, the PSU now has a sensible, replaceable power cable and I can use the PSU of other USB-C laptops if required so getting a spare isn't hard or expensive.
As for supplying more than 5V or more than 8W, the cables communicate with the power supply what they can handle so you don't have that risk that originally prompted Apple to come up with the lightning connector: standard USB cables have no built-in controls, so if you want to send 2.4A charging power down a pipe it's better to make sure it's a cable you can trust and is rated for that sort of power. Hence the chip in lightning connectors and now universally in USB-C connectors - a passive cable won't be fed anything more than 5V.
Yes, it's a pain, but at least it's a one-off pain. I've used VGA, DVI, HDMI 1080 and all of that, and USB A, USB3 and every conceivable power connector under the sun with laptops over the years. USB-C means I can retire half a cabinet full of cable, plus I don't have to worry I've forgotten the one cable I need when I travel or that a cable won't fit in someone else's modern laptop if they need it. It cuts down something fierce on the stock of cabling a support department needs to hold too.
So, if this was dreamt up by a Crayon Dept, I want some of those crayons because they clearly did a damn good job.
* But yes, I do miss that universal 3.5mm jack. That's been with us for so long, like 6 or 7 DECADES. In IT terms, that's pretty much forever.
