The A.I (A.I.Reader/RWBY)

Its funny right? I know i shouldn't laugh at it but its funny to me, Rampancy is something that an A.i fear.. but i find it hilarious for some reason, for example! An A.I has to go through three stages? Well i mean people say four but who knows. Ok stage one Melancholia! Or Depression i would call it!. Second stage Anger! But why though? Oh and the third stage Jealousy! Its funny because.. I'm an A.i and i don't have these feelings, the only one's i have are humor and happiness.. but now a days i feel Depressed why?
