"Lekgolo are also able to integrate themselves into machinery such as the Scarab and use their combined intelligence to pilot, or control, the vehicle or machinery." "Every worm-like creature is an individual eel, about 1.4 meters long, with its own central nervous system. It is speculated that the Lekgolo have microscopic muscular cilia which are used to connect to other Lekgolo and that each cilium is capable of communicating chemically similar to a synapse, explaining how the species can become a collective being in the form of the Mgalekgolo." They work as one, or as close as you can get to it without being telepaths. And, like anything with a brain, if you put two people together in a room instead of one who's working on a complicated set of calculations, that right there means there's more room for computational power between the two individuals. Which in itself is how the flood works when on large planetary scale. They don't only consume geniuses. There's dumb folks in the collective too. But that doesn't matter. So long as the brain has a simple understanding of mathematics, it can be used in conjunction with another. So if you had this mass of Lekegolo that was connected to one another on a planetary scale, do you think they'd all be able to solve complex equations if they worked as one, crunching the numbers together?
