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.
Crocker's Rules
I am suggesting your comment implied to me you still compare AIs with humans a bit too much. We work to make software able to solve the set of problems it was designed for. This applies for Hello World, and for Singleton.
Single-use software has its place, but it's not exactly singularity-inducing. Each piece of software can only do one thing. If you had a piece of software that could do anything, then you program that one piece of software and you and everyone else is set until the heat death of the universe.
Also, why bother with the word AI? Even if AGI isn't its own cluster in thingspace, we already have the word "software". Why replace it?
