When I am not in actual meetings, I do already spend all day talking to anthropomorphized facets of my personality that represent software architecture, security paranoia, operational practicality, user experience, etc. Often not by speaking aloud, but it's a conversation nonetheless.
So yes, this sounds absolutely grand.
EDIT: But I don't think it should be forced on everyone! Having the option to use the tools that work best for you should be the goal.
