Correct.
Since math is a language and is itself described by language, that folds all the natural sciences (as they are described by math) into social constructs as well, and since engineering is just applied science, engineering is a social construct. Which means that civil engineers assign whether or not a bridge will hold under a given load and conditions, as opposed to it being some properties of the bridge itself independent of the language being used to describe it that determine what loads and conditions it can successfully operate under? No?
Sex is the same way. Sex predates language. Sex predates humans. Sex predates the entirety of organisms we would classify under Kingdom Animalia. It predates any living thing complex enough to have a language. It exists independent of the language used to describe it. You can easily make the argument that’s not true for gender, because unlike sex it doesn’t exist outside the language and societal structures built around it.
I don’t know, I wouldn’t mind also being able to tell it to start to preheat while I’m on my way home. Would save a chunk of time if I could literally walk in the door and throw the food in the oven without the extra wait for it to preheat which is usually long enough to be annoying but not long enough to do anything else.
