They are, notably, the computational foundation of contemporary Large Language Models (LLMs). LLMs’ facility with language have led many to draw analogies between LLMs and human cognitive processing. Drawing out the consequences of what seems like an innocuous step—the need for positional encoding of the input to LLMs—I argue that transformers are broad precisely because they have so little built-in representational structure. This naturally raises questions about the need for structured representations and what (if any) advantage they might have over mere representation of structure. I develop this in particular in the context of the contemporary revival of the Language of Thought hypothesis.</span><o:p></o:p></p><div style='margin-top:12.0pt;margin-bottom:12.0pt;font-variant-ligatures:normal;font-variant-caps:normal;font-variant-numeric:inherit;font-variant-east-asian:inherit;font-variant-alternates:inherit;font-stretch:inherit;line-height:inherit;font-size-adjust:inherit;font-kerning:inherit;font-feature-settings:inherit;orphans:2;text-align:start;widows:2;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;word-spacing:0px'><p class=MsoNormal style='background:white;vertical-align:baseline'><i><span style='font-size:12.0pt;font-family:"Aptos",sans-serif;color:black'>A reception with light refreshments will follow the Talk in The Center on the 11<sup>th</sup> floor from 5-6pm.</span></i><o:p></o:p></p><p class=MsoNormal style='background:white;vertical-align:baseline'><span style='font-size:12.0pt;font-family:"Aptos",sans-serif;color:black'> </span><o:p></o:p></p></div><div style='margin-top:12.0pt;margin-bottom:12.0pt;font-variant-ligatures:normal;font-variant-caps:normal;font-variant-numeric:inherit;font-variant-east-asian:inherit;font-variant-alternates:inherit;font-stretch:inherit;line-height:inherit;font-size-adjust:inherit;font-kerning:inherit;font-feature-settings:inherit;orphans:2;text-align:start;widows:2;-webkit-text-stroke-width:0px;text-decoration-style:initial;text-decoration-color:initial;word-spacing:0px'><p class=MsoNormal style='background:white;vertical-align:baseline'><b><span style='font-size:12.0pt;font-family:"inherit",serif;color:black;border:none windowtext 1.0pt;padding:0in'>Can’t make it in-person?
