Robots feels like the wrong wildcard though. How do you turn automated factories into biologists? If I had to pick a wild card it would either be colonists or infrastructure. You can train the colonists to be other things or you can dedicate the infrastructure to supporting the resource type you want.

You dedicate your automated factory to biological research. Or you program your robot arm to perform surgery.

Colonists would also work, although I’m not sure if turning Colonists into Robots is more or less plausible than turning Robots into Colonists.
