AGI being possible (potentially even inevitable) doesn’t mean that AGI based on LLMs is possible, and it’s LLMs that investors have bet on. It’s been pretty obvious for a while that certain problems that LLMs have aren’t getting better as models get larger, so there are no grounds to expect that just making models larger is the answer to AGI. It’s pretty reasonable to extrapolate that to say LLM-based AGI is impossible, and that’s what the article’s discussing.
You not mentioning LLMs doesn’t mean the post you were replying to wasn’t talking about LLM-based AGI. If someone responds to an article about the obvious improbability of LLM-based AGI with a comment about the obviously make-believe genie, the only obviously make-believe genie they could be referring to is the one from the article. If they’re referring to something outside the article, there’s nothing more to suggest it’s non-LLM-based AGI than there is Robin Williams’ character from Aladdin.
