"We've also discussed how homogeneity is valuable to an early startup. Having everyone be culturally similar may allow faster pivoting and interpersonal comprehension."

Homogeneity is also the natural state for human beings and not necessarily a sinister plot. If you solve our natural tendency to surround ourselves with people who look and act like us, you'll probably have solved racism, sexism, ageism and just about every other -ism. I' not saying we shouldn't challenge this instinct, but I also don't think we should be surprised that white, 25-year-old, male founders have a tendency to hire other white males in their mid-twenties.
