GPUs in gaming laptops use WAY more power than even the hungriest mobile CPU. Strong mobile CPUs like the Ryzen 5800H are usually in the 45W ballpark while mobile RTX 3080 class GPUs can go as far as 170W+ and that is still half of what the desktop equivalent can draw.
What's the cooling situation on such a laptop?
USB-C is about to go from 100W to 240W, enough to power beefier laptops

At which point do we change assumptions about safety of USB cables though? Myself and most people I know always considered USB connection to be safe-ish - that is, you can keep the cable connected on the supply side, and have the receiver end just lie on the desk on the floor, and the worst that could possibly happen is some tiny sparking if the stray end touches something conductive in a very unlucky way. But the mo…
I mean, I share that worry, but isn’t the “-PD” part of “USB-PD” a negotiation step? I have very little worry that my carpet can accidentally negotiate 60w and up. I _am_ worried about cheap USB-PD devices that forgoe this negotiation as it is complex and expensive to implement.
If you buy a fake cable that pretends to have display-port alternate mode or something but doesn't, meh, you're out 10 bucks. But if it pretends to be able to carry 200 W but isn't and burns your house down instead, you might be out a tad bit more...

#2550 volt @ 5 amps? Better make sure your ports don't have any lint inside. And don't forget your special EPR certified 240W USB-C cable, of course. The U in USB stands for "universal", but it feels like USB is trying to target a very niche market with this.

#26I look forward to USB 4.1a Type C.2 Phase iii.b Gen 3E and the 482646282 different cable capability combinations that all plug in and have no distinction of those capabilities whatsoever. I also look forward to all the necessary and helpful posts telling me how the identical ports on my laptop are in fact diffferent despite their identical appearance. But at least everything uses the same plug, so that’s nice.
I'm not enthusiastic about wading into the world of "every port looks identical but isn't" that USB-C has given us. I have to keep my cell phone charger cable with the charger at all times, because it's my only cable compatible with Qualcomm quick charging. Naturally, there's no visible indication of this.

#28Laptops shouldn't ever need 240W. That's just getting stupid. Buy a desktop if this is what you need!
I can't take a desktop with me on an airplane.

Here are 10 different cables, you must accurately describe each of their features in detail (USB speeds, charging speeds/power delivery, video out? What version of Display Port does it support?). Make one mistake and you'll be executed.
Obviously I don't advocate for that but it's damn annoying you can have one cable do so many different things and not know by looking at it. At least USB 3 was often times blue to offer a distinction.
These days I plug in a cable and prey it functions as advertised (sometimes it's 50/50).
Awful mess.
