My dad was ha car paint goroo, a little it of a niche not going to win the nobel prize in chemistry. He talked a lot about leaving dupont and about start ups and doing something on his own, and he never did. So my dad absolutely yearned for the new, but clung to the familiar. And if i just play out what i think happened, it might be operating for some of these people that david wants to recruit. For my dadd i think it was deeply fear. The equation, if it had a number for if this goes wrong, that was a very big negative number for him.
