Yes, that's a fair point--the numbers for the potential upside and downside matter a lot here. I was only trying to make the case that in some cases, the downside risk may not hold a candle to the potential upside.

I also think that they want to see founders who are willing to charge up those hills rather than to shirk away from challenges that seem to be too big for them. Sort of like burning your ships behind you in terms of morale--if it's go big or go home and you can't go home, there's only one choice left.
