That's fire. Imagine the potential applications outside of limb replacement
why train someone to use a remote controlled robot when someone with a bionic hand is able to perform tasks that might be difficult to get an entire person to tight spot or dangerous area.. get a drone to drop off some hands...
train people with bionic hands to disable bombs from a safe distance.
soldiers can carry bionic arms that are connected to surgeons remotely who can operate or provide treatment remotely.
the uses cases are immense since there are over 2 million americans with upper limb loss who could be trained for anything..
