What if that achievement never happens, that is the "pure spider silk milestone" ... What has been accomplished thus far is an important milestone, that is the creation of transgenic silkworms that are able to spin spider silk structurally integrated in the native silkworm silk ... The fiber properties as announced earlier are already an improvement over silkworm silk ... Therefore with the creation of a wide array of transgenics capable of producing a wide array of fibers with a whole host of properties suited for various commercial applications would be the goal ... I could care less if this so called "pure spider silk" never happens ... If it does, more power to all of us but that's NOT why I'm investing in this company ...
