Sure, computers can be very helpful to master certain skills like learning to read music or maybe mastering some aspect of technique. But to decompose music into aspects like tone, pace and so on is a huge oversimplification. And by learning to play piano I assume one want's to play music. Playing piano again in my view is about hearing, you have to play it in mind, make it sing, and only then bring that to the instrument. The instrument is just a tool.
