Cyberneticist → It is formed from "cybernetics" (from Greek "kybernētikós", meaning skilled in steering or governing) and "-ist" (meaning one who practices or is concerned with). A cyberneticist is someone who practices or is concerned with the science of communication and control in living organisms and machines.
Think of someone who is skilled in 'steering' or 'governing' systems — that's what a cyberneticist does, as they work with the control and communication in both machines and living beings.
