One thing it doesn't do, that would be particularly powerful, is emulate the geometry of the human arm. If it did, and it if it was typically paired with a mirror image arm, you would be able to very easily train it to do most tasks that can be done by a human. Instead of "programming" it to, say, iron a shirt, you just get someone who is good at ironing shirts to do the task over and over while it copies them, gradually improving its abilities.

Combine that with designing it in a way that it can do a large part of making new robot arms, and the costs should drop and the capabilities should increase....dramatically.
