There are 300 different usb-c form factors. I can't charge my old phone with my new phone charger or vice-versa even though it's all usb-c. Also usb-c very easily detaches and the connections are pretty sensitive, which makes it less than ideal for serious use.

For charging, the best port is the barrel port. It's the most robust and it can totally also be universal, there's nothing preventing this but, as you said, how bad modern tech is with things like that.

Even if we ignore all that, you're not talking about tech at all, you're talking about standardization, which is a totally different and unrelated topic. The advent of standards is always a mixed bag. One the one side at least there is, well, a standard. On the other, almost always, the worst technology is chosen as the harbinger.

Also enjoy your shitty chinkpad that cost 2x what the equivalent macshit costs while being built worse than a $200 shitbook. You wanted new tech, have at it.
