Developing fine motor control for cursive is actually improving cerebellar function. It turns out that the cerebellum is a general "organ" for fine control and synchronization of neural function across the brain. It is implicated in:

* Reading and responding to other people's emotions. * Emotional regulation. * Generalized sequencing. * Musical ability. * Counting. * Following patterns.

While you may see it as a waste, you may very well have benefited in significant ways from learning it at a young age.
