Tech prides itself in being more objective, more rational than other fields but in reality is no different.
In other fields the effects of class and network are openly acknowledged, in tech you to even address the issue you first have to punch through the mythos.
In other fields the open acknowledgment of these issues has resulted in some action to de-bias the system (see: blind auditions for orchestras, residency matching for doctors). These efforts are imperfect, but nonetheless still way further along than anything we have.
Don't let the perfect be the enemy of the good.
