If Internet cables can carry a lot of data per second, why won’t these cables replace HDMI/VGA/DVI standards?

“If trains can carry a lot of people very fast, why don’t they replace walking, biking, cars, and planes?”
Different strengths and drawbacks is the short answer. Being single-purpose (only image data) has advantages over a genera purpose bus, and point-to-point connections also don’t need to have a forwarding or routing protocol to go with them. Data can be preprocessed in a way that is easier for the end device to decode, so the receiver can be simpler and cheaper. Physical connectors and cable can be made without caring as much about long-range performance if you can assume that the devices will always be close to each other. And on and on.
“Data” is always the same in an abstract sense, but in a physical sense there’s a lot of possible paths you can take to create a data transport system.
