“Information download” is a genius term. In the right industry a company can save years of failure by paying the right person for X amount of hours to glean a ton of knowledge very quickly, assuming they can’t just outright hire them.
Mathematically this probably could never be justified as a permanent hire. Not enough steady demand.
It can be justified in the context of hiring that person keeps that knowledge resource from competitors. Then it makes a lot of sense to pay them enough to stay, as it allows you to outpace competition in the marketplace.
What does it take to become this kind of person in less than 10 years?
