Slime molds [are fascinating](https://www.youtube.com/watch?v=dYQG6ac38UA). They can live as single-celled organisms or work together as a colony that differentiates functions and exhibits learning behaviors without having anything like a brain. Training one slime mold and then allowing it to fuse with another transmits the training with the new slime mold.
@johnnylogic The slime mould that is, not the computer scientists. Computer scientists suck at solving mazes and designing efficient networks lol
