Doubting Non-Fiction now

To all those who know more than I:

It has long been my intention to write both fiction and also non-fiction (Non-fiction being based on my CSI career). I was hoping sales would at least support each other. Recently, though I listened to an interview with Thomas. He spoke about his creation of AI Thomas and the different editions of the maternity book What to Expect , and how It had shifted away from print.

I thought he made the comment that non-fiction books could be superseded by subject matter chatbots. As usual he made some good points. I’m no AI WIZARD, so I’m concerned about having success writing non-fiction. Should I be?
