In hindsight it's always easy. You know what, the book authors wrote the book in 1999 for the general public, the average joe who bought tech stock without much knowledge. Many insiders from the valley knew about the bubble, yet your grandma in Texas never heard about it in 1999 or Jan/Feb2000. That's why that book helped lot's of people to get out of it, right before the crash - it doesn't matter when the crash happen, a few months before is better than a months too late, isn't it? Well the one amd two star reviewers thought they were clever or were heavily invested insiders (like you/other downvoter now?). Petty for them that those probably lost their money. It's always good to learn from history.
