I love that to play an instrument with some level of proficiency, it takes physical practice. I love that to get good at dancing, sports, or martial arts - takes physical practice. That these things engage your whole beingThat part of the joy from these kinds of activities comes from the time that is invested, the changes and improvements that are experienced over time. I love that we have muscle memory - that our bodies can be trained to respond faster than our thinking mind in various situations.
To me, while it could take some cognitive work up front in terms of synthesis, composition, and arrangement - the otherwise instantaneous transmission of this product from thought to machine strikes me, at worst, as yet another technological solution for a problem that doesn't exist. Not to say that it would never be useful. Just srsly... do we need an app for everything that could ever possibly exist?
