Typos and poor grammar everywhere, a better editor is my biggest recommendation to the author.
If you are brand new to the concepts in the title, you may enjoy this as a quick skim. However if you have read a few blogs on these topics, there isn't much content here. I was hoping for a book that described web3 concepts and use cases in-depth, but much of the talk is surface level that follows a consistent structure. 1. Here are X examples of how Y is changing the world. 2. Example X: This is really great, it is going to do really cool things, what are those things? Well here are some links to things that are cool. 3. That wraps up the list of cool examples of X thing.
Again, if you're looking for something high-level and don't want to go into the weeds on any of these topics, give this a try.
