Because the tech landscape changes, and in a few years the tech skills you have will become outdated. Nobody will tell you this, though, so you'll confidently and move forward in your MBA career thinking you're still as good as you were when you developed full time. In a few years, you're going to butt heads with a developer who tells you you are wrong, but because you are an MBA and you used to develop, you must be right. I deal with this all the time as a developer. I am tired of guys who "used to develop, so they know what they're talking about".
