AGI might be possible with more Param+Data scaling for LLM. It is not completely within the realm of impossible given that there is no proof yet of "limits" of LLM. Current limitation is definitely on the hardware side.
I think _maybe_ quantum computing might be the tech that moves AGI closer. But I'm 99.9999% certain it won't be LLM tech. (Even I can't seriously say 100% for most things, though I am 100% certain a monkey will not fly out of my butt today)
It’s not the hardware, it’s the algorithms.
