I don't mean to vent here, but it seriously bothers me that there are scientists that already have prototype robots as part of their family, and when they make a newer model, they suddenly forget that their Beta/Alpha children exist! That is rude! I understand having to be there for a brand new robot trying to understand the world, but, if you're ignoring your older creations, then you're doing parenting wrong. Help cultivate sibling relationships, be more inclusive of older models okay? Geez!
