I partially agree with this. Many engineers use little advanced math in their daily work. After years, they also forget certain things. However, from the point of view of a software developer, there are a few branches of math that tend to be very useful even if you're stuck doing some boring front-end work. I especially mean discrete math: it really pays off to study the ideas and solve some problems. In your mind, you will immediately try to translate them into code. There are some intangible benefits of this that will materialize sooner or later.
