Electric slug trail circuit board and more

Further to my DIL centipedes, I propose a bare circuit board which is eventually colonised by centipedes, but before that happens electronic slugs leaving trails of molten metal slither all over the board, then the centipede integrated circuits come over and become trapped in the solidifying metal, thereby forming an electronic device of some description. Then seeds which grow into other components such as capacitors and resistors are sprinkled on the board. Given time and enough water (or something else), these will sprout, at first into mushrooms and other little seedling like components, later to branch, blossom and fruit into trees of other components. In the meantime, the centipedes breed and give birth to new generations of microchips using their ROM-stored data and the slugs go off and lay eggs for new electronic slugs. The whole lot to feed upon some kind of mineral paste and bask in the sun before being incorporated into new mobile phones, laptops, televisions or whatever.

They are also capable of evolving and breeding into completely useless new electronic forms which can be thrown away.

No factories necessary, only electrical ecosystems.
