Not necessarily, in this case I didn't reject the phrase "I dropped the pencil on the table and it smashed." as semantically implausible because of its context (it was used close to similar-looking phrases). Of course that it doesn't inform us anything about any "pencil" nor "table", but it does inform us about the limits (or non-limits) of AI.
