That would be a consequence of your position.
The person who wrote the article is english. The claim being evaluated here is from the article. The term "concept" is english. The *meaning* of that term isn't english, any more than the meaning of "two" is english.
My analysis of "concept" has nothing to do with the english language. "Happy" here stands in for any property-concept and 'dog' any term which can be a object-concept, or a property-concept, or others. If some other language has terms which are translated into terms that do not function in the same way, then that would be a bad translation for the purpose of discussing the structure of concepts.
It is you who are hijacking the meaning of "concept", ignoring the meaning the author intended, substituting one made up 5 minutes ago by self-aggrandising poorly read people in XAI -- and the going off about irrelevant translations into Chinese.
The claim the author made has nothing to do with XAI, nor chinese, nor english. It has to do with mental capacities to "bring objects under a concept", partition experience into its conceptual structure ("conceptualise"), simulate scenarios based on compositions of concepts ("the imagination") and so on. These are mental capabilities a wide class of animals possess, who know no language; that LLMs do not possess.
