I do think diversity is a good thing but it is overrated and politicised by ideologues.
Quality of work and output in most spheres is largely aided by diversity. New people bring new ideas without which the mindset of “we’ve always done it this way” will prevail for longer.
I’m watching The Boys on Amazon Prime just now. It amazing, but with an all white cast it wouldn’t make sense.
I can think of some positives, such as new ways of working like you say, or different types of cuisine/fashion etc.
I just think these are far outweighed by the negatives which are endless IMO.
For me, society is at it's strongest when hierarchy is clearly defined, and uniformity in terms of culture, religion, earnings within class as well as ethnicity overall is sought.
The quest for wage equality will always be doomed too, because different groups have different characteristics and interests.
I'm pretty sure the gender pay gap increased slightly in my company recently! **sniggers**
