That's also not true. A base LLM like GPT-3, without any (specialized) training data, alignment, or prompt engineering, embodied quite a bit of agency (able to answer questions, simulate coding, or take actions in a while-loop), and in principle, can be AGI if scaled up. Consider Gato for an example: no alignment, no prompt engineering, just a GPT on data. This is unlike a stone soup which is completely un-nutritious without the villagers donating all the edible ingredients to make an actual soup, where the stone itself does nothing (a LLM definitely does something); the two scenarios are different qualitatively, not just quantitatively. Gopnik's analogy and goal for her analogy are both irretrievably flawed.

This analogy didn't melt after being pushed too far. It caught on fire spontaneously in the garage while no one was looking before half the parts arrived or had been unpacked.
