Why do you think you have to limit your interests to one area? You can be a musician who hobbies in robotics, or you can be an engineer/scientist/CS who plays trumpet for relaxation. In fact, there were studies that showed computer programmers were much more likely to appreciate and participate in music than the general population; they suspected it was something to do with the same parts of the brain being used for both activities. And as an anecdote, when my son was in the University of Michigan Marching Band a couple years ago, there were more students from the College of Engineering than from any other school.
