This kind of books are key to getting started with Machine Learning/AI, and this particular book is a very good one. I started my ML journey with this book.
There is a lot of hype around AI and it is going to be like the dotcom bubble.
Unlike Crypto, AI has real uses right now and I am saying this not taking into account any LLM products. But there is also a lot of hype and wishful thinking, and this bubble is going to burst and hurt a lot of people. But that won't stop people making real money in the short term. Many hypers I know understand this well.
But AI is here to stay. And even after the bubble bursts, there will be real uses of AI all around us.
