In sum, CEO Brian Chesky brought me in for my industry knowledge, but what I really offered was my well-earned wisdom.Maybe it's time we retire the term "knowledge worker" and replaced it with "wisdom worker."We have five generations in the workplace today, and we can operate like separate isolationist countries,or we can actually start to find a way to bridge these generational borders.And it's time for us to actually look at how to change up the physics of wisdom so it actually flows in both directions,from old to young and from young to old.How can you apply this in your own life?Personally, who can you reach out to to create a mutual mentorship relationship?And organizationally, how can you create the conditions to foster an intergenerational flow of wisdom?This is the new sharing economy. Thank you.
