I is used a lot by myself. Thus I predict that all IEIs use I as a thing. This can probably be confused with other types that also use the I, but in a not "royal" way. Hrrm. Don't know how one would tell the difference. Hrrm. And please excuse my use of th word royal. It isn't anything narcissist. I compare it to the royal we when describing your people. I'm describing myself like I am a nation.
