The bet is a punctuation point on a discussion. Sam is already taking risk on current valuations, another $100K here or there isn't going to move the needle. The real stakes are reputation for prognostication. And the point to me is getting VCs on the other side of the debate to put a public stake in the ground, and hopefully give their arguments for why.

So I don't find this taker particularly interesting. In the context of an industry wide debate, the opinion of someone who doesn't have an audience similar to Sam's doesn't really mean much. Not that they aren't smart, just that they aren't someone influencing the discussion. Which is what this is mostly about.

And to say "I take the bet" without any discussion of why really misses the whole point.

Of course Sam should take this bet. But I'd suggest that he amend his proposal: Find people with enough audience to change the discussion, who are talking about bubble valuations, and ask them specifically to put a stake in the ground on this.
