What really frustrates me when I watch this kind of demonstrations with bionics is the delay and inaccuracy between desired action and the real effect. I know it's not that simple, but from my perspective since the desired actions are transmitted through our nerves at 100 m/s and we can send an message thousands of kms away in milliseconds, I think there is always space for improvement. I am curious which is the real bottleneck in all the process.

As you can see in the video https://www.youtube.com/watch?v=HjW1kIt5iQg there is some latency. Weinberg and Barnes are working to fix that, but I don't know details. Weinberg said he wants to gather more data from more users so the arm is more useful to more people.

But why should one rely on the termination of the nerves instead of the implating an electrode on the main cortex which controls the motor activity? Can't they translate directly the actions from the energy flow at that level?
