Great post. Very insightful. As we are moving towards roles(and are letting go of jobs) aren't we also moving back to tribes? Isn't working in tribes part of human nature. Isn't humanity freed up again, as we have automated "work". It feels like we created a full transformation. We have build a layer on top of nature that works for us. Now we are starting over again. Building tribes on top of our networks. Tribes in which we organize ourselves around meaningful challenges triggered out of our networks(the source). We contribute in these challenges by stepping into roles and delivering creative work linked to our skills.
