Well the latest episode cleared up some stuff for me, I'd been wondering how exactly everyone was able to see/hear the guns and after this episode I'm guessing they all have computer implants like the reporter lady did (since obviously she didn't think anything of having them so they must be rather common). And there was also that interesting line about how people who spent more time around the elderly as children seem to bond with their home AIs better and Akane's jellyfish has acted not exactly as a parent but as a caretaker for her, both taking care of and spoiling a bit, like the way an extended family member might act. Or they could've just had that line to fill time/make the professor seem even smarter.
