My take from this article: so basically, what separates a staff engineer from a freelancer or company owner is mainly uncertainty or risk adversity. They must already have everything else it takes to succeed, since it's a requirement for the job. But the vision and drive to go in for themselves is not a requirement and if they don't have it, they will become a valued staff engineer. I'm not sure I buy it, but that's how it comes across, since a staff engineer is supposed to be blessed with all these wonderful talents.
