This is one of about a dozen technology advancements that I feel we’re on the cusp of, and have awaited for sometime. And I believe will be feasible in my life time.
I know it’s off topic, but it’s neat technology. And for those who have been injured, it will greatly help their ability to live normal lives. I wager there are a number of U.S. soldiers who will never fire another rifle due to injuries in Iraq and Afghanistan, unless technology like this becomes available.
