I usually try to keep up with what's going on in robotics and prostheses developpment to try and make the cybernetics in my story as up to date as possible. I've also got a couple of articles lined up on necrorobotics (exactly what it sounds like) for future reference to read up on.
Also fun fact about the days of the week in english, whereas in other languages like French the days of the week are pretty explicitly all named for Latin gods, English has a couple of weird ones that don't seem to fit like Wednesday is nothing like "Mercurius", Thursday is not Jupiter and Friday is not Venus (where as in French it's pretty obvious: Mercredi, Jeudi, Vendredi).
That's because in English all days of the week used to be named for the Norse gods, and when the Romans invaded they thought Norse gods were just Latin gods with different names and worked hard in the parts of England them conquered to make that seem true to more easily transition the population from Norse to Latin beliefs. However they didn't conquer all of England nor did they conquer all the days, leading do the English adopting the order of the days but using the Norse God's names, so sun and moon, easy, Tį»³r's-day (Tuesday), Odin's-day (Wednesday) Thor's-day
(Thursday) and Frigg/Frejya's-day (Friday) surviving.
It was thought that Tį»³r the god of war was Mars' counterpart, that Odin was an analogue to Mercury, being both somewhat gods of knowledge and wisdom as Mercury is god of apothicaires and messengers, that Thor was an analogue for Jupiter with them both having thunder powers, and Venus an analogue for Freyja as they're both goddesses of fertility (though Frejya's probably closer to Demeter in her status of goddess of nature and plenty).
All that to say that in your worldbuilding different parts of naming and speech can come from different influences and peoples in your world as they do ours.
