Separation perhaps, but we would be committing a major disservice to knowledge if we were not to acknowledge that both language and thought must derive in some way from deeper principles of self-organisational complexity in (and as) information, energy and logical or material communications systems in nature and physics. Language may be separable from thought but what does it tell us of our predicament when we are still bound by language and its variously unresolvable word-games to explain this, intra- or inter-personally?
Large Language Models manifest many lessons and insights for us but do we even notice as they generate precisely the kinds of discourse and language in culture and technology that provides an optimal transmission medium for its own exponentiated invocation? There is a mischievously opaque recursive sweetspot here and I am uncertain that it is getting the attention it deserves.
