When the scientific and technological fruits of artificial life are embodied in technology with real practical use, sometimes the result can properly be called living technology [6]. Technology today is becoming increasingly lifelike, and there has recently been increasing foundational discussion of the broader scientific, socioeconomic, cultural, and ethical implications of living technology (e.g., [5, 7]).
