I see what you're doing there crunchyroll, getting us hooked on the first episode so we get premium membership.
All well, I'm liking it thus far so nice play!
We as humans do not know what it's like to not have a personality so we can't relate to things that don't and thus treat them as if they have personalities. Quite simple.
People have sympathetic reactions to machines already. I know other people who cajole, threaten and beg their cars to work. Thanking a machine doesn't make logical sense, but it's not really too abnormal.
Well, if my CD Player look my size and and looked at me and said "CD Ejected", I probably would thank it too, lest it goes haywire and beats my bone and flesh butt! It wouldn't be the only pointless thing I have ever done. lol
I love that the characters have very human personalities. there's a lot of depth that most anime lack. It's not about being cute so it doesn't lose personality
One thing I don't get is why he reacts as if he's outraged. It can be a shock, but rather than be fascinated, he seems only revolted at first.
I would be greatly in awe and curious and not stop short of a convo with my droid.
