I believe vba616 is trying to point out that if we consider AI systems that   
  generate plausible-sounding responses to be "bullshitting," then we should 
  also acknowledge that humans who do the same are not necessarily 
  distinguishable from "intelligent" humans. In other words, both AI systems 
  and humans can produce seemingly coherent responses without necessarily 
  having a deep understanding of the subject matter.

  It raises the question of whether we should hold AI systems to the same 
  standard as humans when it comes to evaluating their output or 
  understanding. If we accept that humans can sometimes provide plausible yet 
  shallow answers, should we not also accept that AI systems, like LLMs, can 
  do the same?
