Not that stuff like this isn't a good step. But I actually listenented to a podcast where a lady was interviewed who had one of these (not the exact same company/model but the same bionic arm deal). Anyway she actually ended up hating the thing since it is both harder to user than a static prosthetic and needs to be charged. And all of that is on top of the fact she had spent thousands of dollars to get the thing in the first place.
I'm really happy we're making advancements in this field but it does sound like it has a really long way to go
