> Any person worth reading in STEM fields already knows English, and I don't know why anyone would want to read Wikipedia in any language other than English

That's not the goal of Wikipedia. The goal is to make knowledge freely available to as many people as possible. That's fantastic that you were given the opportunity to learn English and have made the best of it. That is not everyone though. It's not reasonable to expect a farmer in Malaysia to know English or to learn it purely to take advantage of what's there.
