A 4 year old is currently more capable than LLMs (I'm not making this up, ask Yann LeCun). You're going to need it to reach at least "adult" level to be general intelligence.
It seems more like people haven't decided on what the goal post is. If AGI is just another human, that's pretty underwhelming. That's why people are imagining something that surpasses humans by heaps and bounds in terms of reasoning, leading to wondrous new discoveries.
AGI just means human level intelligence. I couldn't come up with General Relativity. That doesn't mean I don't have general intelligence.
I don't understand why people are moving the goalposts.
