I think you're pigeon-holing me a bit into a spot where you view me taking a moral stance with no external logic. Eg. I am a well meaning but ultimately naive savior-person that wants to create fairness and this doesn't help the company, the product, or the team. I feel like I'm becoming a projection for frustrations you have with those on a moral crusade.
I disagree that there is no logic to DEI. Specifically the idealized version of DEI, not whatever implementation company A has. I think a diverse team creates better products. I think diversity around gender/racial lines are stronger indicators of diverse experience than a wishy-washy "diversity of thought" angle that I see going around.
I also assert that, honestly, from a practical standpoint race/gender selection is easier to select for than most other forms of diversity. We use inexact tools as a heuristic for technical ability (leetcode, take home project, system design, CS fundamentals, etc), why would diversity be any different?
I assert that our interview tools and processes are inexact and consistently leave talented people off the table due to biases. The reality is if I have 10 candidates for a CRUD position I assert I could pick a name out of a hat and they'd be able to do the job most of the time. I think people pretend they can determine person A is 10% better of a developer than person B in an interview when they really can't. The reality is you could have probably picked B and it wouldn't have been a noticeable change once on the job. I think seeing these "successes" lead people to think they are better at interviews than they really are.
DEI to me is understanding the hiring process has bias + blindspots and taking the gamble that selecting in a differently biased way gets me better odds of getting that "Bangladeshi John von Neumann". And even if it's not a home run like that, that there is still an overall benefit to the added diversity to the team vs taking the person that did 10% better on our leetcode question.
