Right - I get that, and you make a fair (and valid!) point. Nobody knows where the top is. It's all hypothetical.

But my point is that when you're seeing hypergrowth in your company, you probably have an idea of what it's worth or what level you're happy walking away at. Example: I currently run a small side-hustle culinary business while I look for a full-time tech gig. It doesn't make me much money but I enjoy doing it and it helps put food on the table. If someone came up and offered me a million dollars to walk away, I'd take it without blinking.

If Yahoo offered Zuck 10 billion way back when instead of 1 billion, I have a feeling he would have walked away, too.
