From Charles F. Barth:

Re: Robots designed to develop emotions through rel ationships (Aug. 10): The article describing emotional responses by robots to actions of their human caregivers is exciting! These initial results represent a major step towards development of sentinent machines. Such machines, when adequately developed, would eventually be ideal candidates for space exploration and avoid the myriad challenges of long travel times and exposure to damaging radiation in space.
