The goal of the tech recruitment process is fundamentally about finding the best person for the job. The simple truth is that by eliminating unconscious bias in recruitment, you access more qualified candidates than you could before.
I think you would be hard-pressed to find a person in tech who goes into the recruitment process consciously giving into their biases. In the same way, I think you would be hard-pressed to find a hiker who goes into the mountains expecting to be saved by mountain rescue.
Unfortunately, hikers still get stranded and there is still evidence that the tech industry is rife with bias. The Stack Overflow 2017 Developer Survey found that their respondents who were professional developers were almost 90% male and almost 80% white.
