Creating a work environment where everyone is focused on the invention, engineering and delivery is a delicate and inspiring challenge. There are many people who are focused on agendas outside of the core goal of creating amazing tech. Those distractions are often the death of creativity; yet as they [are] a normal part of working life it becomes one of the greatest challenges for leaders in tech to permit enough diversity in general thought that creativity can still flourish, but to limit it so that it doesn't drown out the core focus of the work.
It's been my experience that you should seek to build teams that share a passion for the project that is so strong that they either park their biases outside, or they are simply so focussed that they don't even think to bring them to the table. Imagine being "in the zone" and wanting nothing other than to build amazing technology and to work with a peer group who only wants to do the same. So much so you no longer notice race, creed, politics, religion, gender, etc. You are there for the engineering; and the outcome. That is the utopia you should seek as a leader in our industry... And maybe even life in general.
