It&#x27;s the easiest thing in the world to shake your head and laugh at &quot;crazy&quot; valuations. It&#x27;s incredibly tired at this point, maybe it was less so in 2007, but it&#x27;s not an interesting activity in my opinion. And of course there&#x27;s never any pressure to walk any of it back, this is the Internet, down the memory hole it goes.<p>Talking about the structural reasons for the crazy valuations may be slightly more stimulating.
