the benefits outweigh the risks. spoken like a true scientist who lives with his head in the clouds totally discounting the number of dumb asses there are out there who want to do evil in the world. why don't you just teach the bad guys how to put the bad virus together (so they don't stumble on it accidently and let it loose), then you can tell them to play nice and not hurt anyone, counting on them to do the right thing. what idiots.
