Areas like this is where 20++ technology will come into its own. The discovering that combine the chemistry, physics and biology of the the modern world is simply astonishing. Bonus points to those that recognize and utilize it.
I imagine the handling of earthworms does not scale particularly well considering the huge amounts of cadmium telluride we'd need (if this ever becomes an actual drug, which probably won't happen). Ideally, we'd find a way to manufacture those enzymes synthetically or at least industrially by means of transgenic bacteria.
