Mostly from conversations in CS grad school ~2012 with research professors doing related work, such as in ANN. At that time at least it was commonly discussed in academia. Perhaps a breakthrough has happened since but not one that I'm aware of.

For example, see the sections "Tests for confirming operational AGI" and "Feasibility" in [1], the $100,000 prize requirements in the Loebner prize [2], or "The integration bottleneck" in The real reasons we don’t have AGI yet [3].
