But for most jobs, it's not just about competency in the role. Agreed that there's a minimum threshold of competence required but after that aren't there other factors that weigh in, including diversity?

I was indifferent towards the topic of inclusivity, till I read about how being full-abled is temporary and we all are at certain points of time disabled due to age/injury & systems that are designed with inclusivity in mind (even a specific category of disability) are beneficial to many kinds of users, say text-to-speech applications.

I'm no DEI expert but allowing for people to participate in society fully as themselves seems like a good thing for the community at large.
