I like our language. The fact that we have three (and probably more) different words for these concepts is useful. When you need to extend the meaning of a word by borrowing it into a technical jargon, you have many more options and the potential for a lot more precision.

Plus, less confusion. ‘Core’ wrt computers means memory. ‘Kernel’ refers to the deep magic of the operating system. No one in the field confuses these two. If they both had the same name, confusion would abound.

This large variety of related words is also a boon to creative writing. Using a slightly different word can evoke different shades of meaning while communicating the same basic idea.

Minimalistic languages are nice at times, but I prefer English.

Hey now, it is just ‘kernel’ to computers. Not core.
