". . . by humans, mostly white, mostly male, who, in the best case, are simply unknowingly biased, . . . "
IRstuff, you do realize that this is not unique to white males !?!? Having traveled somewhat extensively in my career, 21 countries at last count, I can tell you that racial/cultural/you-dress-differently-than-we-do "bias" runs fairly deep in every single culture on the planet. Every one. I've been the butt of jokes and made fun of in more languages than I can keep track of, and you know what, it's perfectly OK because that's just the way people are. I think it is also disingenuous to say that white males are seeking to keep the status quo. The notion that only whites practice bias is just flat out wrong.
I don't know your age or cultural background, I'm in my 50's with a northern and eastern European heritage for the most part, and I can tell you that what I have witnessed over the course of a few decades is a gradual dying off of the old guard "good ole boy" mentality. Yes, it was far worse the generation before mine. There may be pockets of it remaining here and there, but with the upcoming generation, it has largely disappeared. That's just my take, perhaps others have witnessed something different. In spite of all of the "flavor-of-the-day" protest groups, the normalization of gender and race in industry and corporate America has improved in leaps and bounds from where it was.
My 2 cents.
It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
