USB-C charging is truly revolutionary.

USB-C data is a clusterf*k, and worse of all, is not UNIVERSAL anymore.

Is it? I guess it's nice that I can charge my phone with my laptop charger, but it has the same issue as usb-c data where everything physically fits but are incompatible. eg. having to worry about whether a aftermarket charger provides enough voltage/current to charge your laptop.

Well, I tried, and I could charge my Thinkpad using a 5V/2A phone charger and an A->C cable. Very slowly of course, but it worked. If I was somewhere and I had forgotten my laptop charger, I could worry about whether a phone charger will work, but without USB-C, I could be sure that it won't work.

Is yours a recent model? AFAIK most laptops can't charge using phone chargers. They require high voltage that isn't available on low wattage chargers.

Yes, it's a T14 Gen1 (AMD).
You can also charge your phone from your laptop and vice versa. Or one phone from other phone. Or just link two phones with a wired data connection with no power exchange.

There's a lot more flexibility than there was prior to USB-C.

Revolutionary? It's a hot mess. Some usb will charge my phone very slowly, maybe at 3w. Some will charge what I call 'medium', at around 15w, and some at 30w. And the charger that came with it is its own special usb-c thing that isn't standards compliant. I noticed that cord doesn't even attempt to charge my Stadia controller. Sure, they all do plugin and most do charge. But have fun guessing which ones charge at which speed.
