Yeah that's part of the process. Unfortunately a lot of monkeys have been killed in the name of science. It is sad but they are our closest relatives and we have to test these things before they can be used in humans. Just part of the scientific process.

Having a pace maker or insulin pump malfunction will kill you too. I mean shit if your car malfunctioned it could kill you. I think the idea is to test and create redundant safety measures. Not, run away from technology cause its scary like some kind of fucking stupid caveman.
