Because AI researchers have been on the path to AGI several times before until the hype died down and the limitations became apparent. And because nobody knows what it would take to create AGI. But to put a little more behind that, evolution didn't start with language models. It evolved everything else until humans had the ability to invent language. Current AI is going about it completely backwards from how biology did it. Now maybe robotics is doing a little better on that front.
