They just don’t have it in them to jump in and out of situations to think through the most trivial of problems from multiple angles. They don’t know in “5 seconds” if something can be done or if it’s complicated. It’s often a rush to tackle competition or cutting out the oxygen and “do whatever it takes”. Ordering subordinates to “deliver” in 3 weeks.
This is precisely the reason why I love someone like Larry Page or Sergey running Google. They just knew that recruiting Urs Holzle to build world class infrastructure early on was worth it.
A lifetime of learning to take noise in & conclude on the one signal that’s worth it.
