Yes, and most likely more of a paradigm shift. The way deep learning models work is largely around static statistical models. The main issue here isn't the statistical side, but the static nature. For AGI this is a significant hurdle because as the world evolves, or simply these models run into new circumstances, the models will fail.
Its largely the reason why autonomous vehicles have sorta hit a standstill. It's the last 1% (what if an intersection is out, what if the road is poorly maintained, etc.) that are so hard for these models as they require "thought" and not just input/output.
LLMs have shown that large quantities of data seem to approach some sort of generalized knowledge, but researchers don't necessarily agree on that https://arxiv.org/abs/2206.07682. So if we can't get to more emergent abilities, it's unlikely AGI is on the way. But as you said, combining and interweaving these systems may get something close.
