I think there are merits to diversity but of course there are also merits to a fully meritocratic system. But I think the ideal situation would be having a fully meritocratic system that has this "diversity" attribute. I feel as though that is a step up from a fully meritocratic system that has virtually no diversity.
Also, perhaps having diversity would allow for the development of new types of products and services in the tech industry that the "privileged" have no interest in. At least that's what people who call for diversity claim.
