I've always liked the idea of the gentle giga but not too many stories on this site try to write them. In my opinion it's difficult because you have to think of clever ways for the giga gts to interact with humans without harming them, violent giga is easy because they don't care about any of that. The only other story I can remember that had a gentle giga was Utopia by Gerald. Anyway I'm looking forward to what you have planned next!
