  1. While I appreciate the publisher’s honesty in admitting that most of this piece was written by ChatGPT I think that this is unnecessary and extremely lazy. It’s easy enough to compose a summary of this game without the assistance of an AI tool. I don’t mind seeing an LLM being used as a writing aid but using it to compose blog posts is a bad idea and I’m now considering no longer using this Web site as a source for keeping up with the assistive technology field.

    • Hi David,

      Thank you for your comment. I use ChatGPT to summarize content from one or multiple sources, create first drafts, and generate related ideas. I work meticulously to make sure there is no made up information from LLMs in the blog post. I certainly don’t use it to generate blog posts from scratch with no sources or citations.
