Why is I capitalised? (in 'I' and 'I'm')

It’s a proper pronoun?

I assume that ‘his’ and ‘me’ are also proper pronouns (remember, I am dumb to the fundementals of the written language) If so, why is the H not capitalised?

He’s just kidding. There are no “proper pronouns.” He’s making fun of the fact that we capitalize proper nouns.
