I'm pretty happy I wrote an O'Reilly book. It's been a life-long goal of mine. A couple of notes:
* No, I did not chose the cover
* Yes, I think TensorFlow.js is awesome
* No, You don't need a PhD to do AI
* Yes, I think web developers will be the majority of AI developers in the near future
Happy to answer any other questions.
