Hi, I'm the author, I appreciate your comment. You're demonstrating that you still have some rational perspective here; my thesis is that many people have lost that perspective. I am an ex-Googler, and I am seeing more and more talented engineers leave Google to start a "company" with the express goal of getting acquired for talent, sometimes even hoping to get acquired back by Google.
When people see a valuation in the marketplace (eg, a talent acquisition that makes everyone extremely wealthy) and assume they can achieve the same kind of returns with minimal effort, that is the hallmark of a bubble. The same thing happened with day traders and real estate speculation.
