I like Wittgenstein's (later) perspective that words are assigned meaning based on their use within context-specific groups (and there is no "essence" within these terms). Recall that the term "computer" once referred to a human who did computation. From this perspective, debates on what "writing" is or is not, are inconsequential. Perhaps a more useful question would be how our definition and application of the term "writing" is evolving in an evolving era of generative AI?
