"Back in the days", it was a bunch of different ports of different sizes and shapes, and each thing had its own cable that fit into that thing only, and into only port only on the back of the pc. Yes, you needed 20 cables, but things were simple.
Then came the USB... one cable, one protocol for all.... except video (firewire) and storage (esata). Then even those got replaced by USB, as new usb standards made it faster.
And now? You buy a new laptop... usb-c charging, great. You need another charger, you go to the store, find a usb charger, buy it, plugi it in - everything fits - but it won't charge. You need a fast charger... back to the store, bring it home, doesn't charge. You need a PD charger and not a QC charger... store again, new charger... plug it in, doesn't charge. You need a PD charger, that goes up in voltage enough (20V) to charge. Store again, a new one... you plug it in... still nothing. Even though it fits in the hole, not all holes are equal, and you need to plug it into the correct usb port to charge the laptop. Yaay, everthing works! Start a game, play, nice framerate, and bam, battery low warning. Yes, it charges, but your charger is only 45W, and that's not enough, you need a correct wattage one (eg 65W).
And then you go to the store and buy an original charger for your laptop, and you're back at where we were 20 years ago, just with a higher chance of plugging the charger in a wrong port, because it fits in more than one hole.
