The definitions of words are a pragmatic matter; we choose them to make concepts easy to talk about. If the definition of AI were broadened to cover all software, then we would immediately need a new word for "software which is autonomous and general-purpose in a vaguely human-like way", because that's a thing which people want to talk about.
When you start thinking about "chauvinism", with regard to software that exists now, it's... kind of like if someone were to talk about how people were being mean to granite boulders. I'm just scratching my head about how you came to believe that.
Hyperbolic (like 1/x). I feel like you're hinting the answer is exponential, but that implies a constant doubling time, which isn't what we have here.
Turing's Test is from 1950. We don't judge dogs only by how human they are. Judging software by a human ideal is like a species bias.
Software is the new System. It errs. Some errors are jokes (witness funny auto-correct). Driver-less cars don't crash like we do. Maybe a few will.
These processes are our partners now (Siri). Whether a singleton evolves rapidly, software evolves continuously, now.
