Majority of people on earth don't solve hard, unique, but well-defined problems, do we? I dont expect AGI to to solve one of Hilbert's list of problems (yet). Your definition of AGI is a bit too imposing.
Saying that I believe you would get answers from an LLM better than most of the answers you would get from an average human.
IMHO the trend is obvious and we will see if it stalls or keeps the pace.
