"Good luck making good products with a group made of people who look like each other, promote and hire people like them. Actually, try to find one and work for them. Let's see how well this goes."
There is so much wrong with this statement.
Please give us examples of where skin color matters over skill. If you want to build a house, all you need are carpenters, plumbers, electricians, etc. If they are all black, the house will get built. If they are 100% Latino, white, or trans, it will still get built because they have the necessary skills to accomplish the project. If you ask a diverse group of people to build a home, but they don't have any of the required skills, will the home get built? No, of course not. Skills and ability are all that matter, their group identity is meaningless, and the make-up of the group is meaningless.
But I imagine what you are saying is it's better to have a diverse group of skilled people, but can you prove that? How can you tell the difference between a house built by a diverse group of people vs a single group of people? I doubt you can.
This is the problem with DEI thinking. It makes stupid claims about group identity mattering more than actual qualifications. The only thing we should worry about and fight against is discriminatory hiring practices. DEI is institutional discrimination mostly against asians and whites. Discrimination is wrong, no matter which groups it's against.
The reason there are more whites and asians in tech, is because they comprise the majority of the applicants. URM's represent the smallest part of the applicant pool, and for some roles they don't apply at all. But in spite of that, our DEI program insists we must slow down the hiring process and the business to find them. If you all truly cared about diversity in tech, then you would fix the problem at the source, which is increase the talent pool and applicants from URM, instead of making crazy claims about hiring unqualified URM's to meet a diversity target, will make better products.
