I'm not sure I totally buy the "no plasticity" argument. If you are allowed to write to context in an agentic fashion, certainly the LLM can record intermediate answers, go back and re-rank it's memory. The "plasticity" is in the form of data that can be looked up and referenced as a shortcut. I would think this forms a Turing complete system so theoretically it can represent pretty much anything.

no that's not the same thing. plasticity means it starts giving a different output for the same input, because the "logic" changed.

What you're describing is simply changing the input.
