Perhaps not much now but a use for them might come along and it will be good that this will be there ready to fill the need. It's my understanding that quaternions were mostly a curiosity when first described in the mid 1800s but now are used extensively in computing. From wikipedia "quaternions are used in computer graphics, computer vision, robotics, control theory, signal processing, attitude control, physics, bioinformatics, molecular dynamics, computer simulations, and orbital mechanics." When Sir William Rowan Hamilton first described them, he had no concept of most of the above, much less that quaternions would be important for them. Good for us that he still pushed forward with them.
