Hell,LLMs can and do output strings of "I'm AGI", so in some sense we're long past that. The problem is as humans we've never defined what it means for a system to be AGI.
My back of a napkin definition is that AGI, given the same information and tools as an IQ 100 human, is able to do all of the same tasks that you could ask a human to do, at the same quality level, as well as recall the experience some time later, like a human would likely be able to do.
The particular issue here is that is subjective as any other subjective definition. 100 IQ is subjective and a moving target. 100 IQ doesn't even mean you can survive and navigate in the real world. Even worse is all humans cannot do all tasks other humans can do and we'd consider them intelligent.
Furthermore this "must behave like a human" blindness represents both a danger, and a way to miss intelligence capabilities leaving them unused/under capitalized. Humans behave like humans because we have human bodies with particular sets of strengths and weaknesses. Other 'intelligent' actors with different embodiment will necessarily behave differently.
Couple that with humans have become far more intelligent and stronger by using tools, that the ability to 'universally' interface with external tooling, at least in my subjective opinion is what will be the defining factor of higher intelligences.
