Yeah true but that's the thing, years of development. When we talking about only months of development, maybe a year at most, then it's a high risk or high reward thing. It's either going to work straight out of the gate or nothing will work, which will set the world back years then probably. The only true things that can help settle this is either this just disappears which it won't, it becomes like the common cold in a few years which I heard some say or we get a vaccine. Otherwise we're in trouble I guess.
