This is an interesting one. Early in my career I thought it would be a good career move to become knowledgeable in the business domain I was working in (finance/trading). I started investing some time and resources to learn. But before I got too deep, I came to the realization that it wasn't really much help. I could become knowledgeable enough to talk and understand the business like a half-assed rookie trader, and let my technical skills suffer. Or I could spend that time to invest in my technical skills and become a better SWE. This was also around the time that I started to think I didn't want to stay in the finance industry much longer, and obviously the business knowledge would not be portable. That said, I'm still stuck working at a bank, and I completely understand where you're coming from, where the traders come to technology asking us to understand and solve their business problems.
