Re: "That's the future..."
That really depends on your local engineering talent. As a field engineer, the reason I'd get called on quite often being in one of the most remote places on earth, something absolutely essential is broke, and they need an improvised solution "right the fuck now!" In every case, I hadn't ever met, nor been trained on that absolutely essential item.* It certainly helps that my favorite form of snack-food is engineering manuals especially for systems I almost always never meet. Lifelong learning carried to the extreme but there you are.
* - Having to resort to Stone Age, or early Space Age, tech isn't a problem. Unlike most, I've actually made my own stone tools and up the tech stack as well. In about five years, I'll have worked up to air conditioning if it were necessary. I certainly hope I'll never need such, then again Heinlein is my guide here since I was a tyke.
