I think we'll see more specialized models for narrow tasks (think AlphaFold for other challenges in drug discovery, for example) as well, but those will feel like individual, costly, high impact discoveries rather than just generic "AI".
Our world is human-shaped and ultimately people who talk of "AGI" secretly mean an artificial human.
I believe that "intelligence", the way the word is actually used by people, really just means "skillful information processing in pursuit of individual human desires".
As such, it will never be "solved" in any other way than to build an artificial human.
