Dr. Fraser was talking about silks that exceeded the properties of Kevlar well BEFORE Kim announced the “knock in knock out” technological advancement that allowed for the creation of nearly pure spidersilk. I am fairly confident that as long as the silk proteins are structured in a way that they can achieve the necessary tensile strength characteristics required that the silks being developed will exceed the properties of Kevlar. It’s one thing to have increased spidersilk proteins show up in the fiber, but how will those protein structures hold up under testing? We should be moving mountains and Earth to get this nearly pure silk fiber, knits, and weaves — tested. IMHO
