With the soldiers attachment to robots thing: I was in the Army and deployed for a year to AFGN, my team leader had a public funeral for his flesh light at the end of deployment. I don’t want that to seem too crass, I only say it to highlight that people misunderstand soldiers and their sense of humor when they talk about these things. I have not read the study that Kate is referring to, and maybe way off base here, but I’m going to take the anecdote about the EOD guys getting attached to their bots with a grain of salt.
