AI is a confused soup of more or less (un)related concepts: agency, sentience, pattern recognition, unsupervised learning, embodiment, NLP, and goal selection - among others.

IMO the minimal useful definition of AGI would list a set of testable skills that would qualify as AGI, and a more useful definition would be based on quantifiable skill sets that would allow numerical comparisons between humans and AIs.

It seems pointless to speculate when AGI might be a reality when we have only the fuzziest idea what AGI is supposed to look like.
