Bio-computing, though I think quantum grows faster and with less sunlight.

Slime is not a technical term, but biocomputers are very interesting and potentially huge.

Go on .....

From the article:

“Part of the idea of the ongoing research is to include metal nanoparticles and make computers that way, which may involve using living slime mold to lay down circuitry before killing it to leave behind wiring,” she says. “This could be a cheaper and greener way to make circuits.”

Specific applications will depend on how robust the computers are, Gales says. But environmental sensors are one possibility. “Slime mold is happy with damp conditions and sensitive to light so it could be used as a light sensor in a cave network or something.”
