Although I concede that fear is sometimes used to get people to buy things, in the particular case of AI (of all things) wouldn't trying to get some of the $100s of billions being invested in AI be a more effective cash grab?
Hype is messaging designed to attract people. What is attractive about the message, "The AI labs need to be shut down or they are going to get us all killed"?
That is throwing a big old wet blanket on the hype, it seems to me.
If the purpose of writing the book is "a cheap cash grab" (your phrase), why doesn't the book say how wonderful AI will be? Wouldn't that sell many more copies?
I like the title, it sounds humorous.
