Usefulness is here, and has been for a while time. I have been consistent in my stance that AGI will be achieved in the demonstration of iterative, stable self improvement. This can be demonstrated in knowledge creation or skill acquisition.
1. increases in consistency and quality to some specific measure
2. development of human-like qualities - "consciousness"? "Intuition"?
And then we toss the term AGI which is overloaded and ambiguous.
