The core technical claim (drawn from Bender & Koller) of the stochastic parrots paper about LMs is that systems trained on language alone can only learn its form, not its meaning (which requires grounding). Thus, that *a priori* these systems could not exhibit understanding. 2/

What is information, really? Instead of arguing for a single valid interpretation, we propose a pluralistic view where rigorous alternatives coexist — each with affordances and limits Finally published: “Four faces of information in natural systems” 🧵

When is distinguishing imagery from perception really a problem? Is this ever just trivial? In this paper, together with philosopher Nick Shea and @smfleming.bsky.social, we aimed to answer "Why do we need imagination-reality monitoring?" -now out in #NCONSC! academic.oup.com/nc/article/2...

Why do we need imagination–reality monitoring?

Abstract. The ability to imagine scenarios decoupled from the immediate environment supports a wide range of cognitive functions, such as planning, memory,
