It's a fine argument, just rough around the edges:

Human brains use redundancy and the physical independence of neurons to build new pathways over time.

Current LLMs have no redundancy and brittle weights. Their technology and architecture fundamentally prevents them from learning.

I think our understanding of consciousness is developing as we build new edge cases. We have a machine that understands and reacts, but can't learn, grow, or "be" over time in a meaningful way.
