I feel like comparing it to biological systems glances over like half the points the parent makes. Also of course it's a sophisticated autocorrect, there's no system for agency, which is what we also desire from a proper AGI.
I wanted to put the focus on the overused "glorified x thing" sentence, which to me seems to be applicable to just about anything. I didn't want to liken/compare AI to biological systems per se.
You and me think we are but we can't be sure, and many before us have raised a doubt.
As for the prompt(s), to use such a limiting term, they could as well come from a self-reinforcing loop that starts when we're born and is influenced by external stimuli.
LLMs as part of a bigger system that keeps prompting itself, perhaps like our internal conscious thought processes, sounds a lot more like something that might be headed towards AGI. But LLMs on their own aren't it.
