I'm doubtful about that. At least among my cohort (first generation south asian immigrants to the east coast) there's not a strong sense of racial identity. There's strong identity in the sense of ties to religion, home countries, culture, and traditions, but not group identification or a feeling of collective destiny. I recently told my dad about being at a professional event where there were three south asians "at the table" so to speak. He was like "huh, that's interesting." He had a stronger positive reaction when I mentioned that Chris Sununu (governor of New Hampshire) went to the same high school as my brother and me. I have to think it's similar to Jewish Americans--they're not looking up to Mark Zuckerberg because he's Jewish.
I also disagree that Indian kids "should" look up to Pichai or Nadella because of their ethnicity. Insofar as there is an "us"--a definable group with distinct interests--"representation" will never advance those interests. Pichai or Nadella will run their companies how white shareholders want them to, exactly the same way as a white CEO would. They wouldn't have been selected if that wasn't the case. The "representation" doesn't advance the agenda of the group in any meaningful way.
To the contrary, "representation" is used by white people to obtain the support of minority groups without giving them anything. I see white people pressuring my daughter to look up to Kamala Harris (because Harris "looks like her"). This is just manipulation. Harris will not meaningfully advance the distinct interests of south asian people, nor is she a good model of south asian culture or values.
As to your main point--for sure people on the internet have better manners today. Is that creditable to DEI initiatives? Can we have online spaces and workplaces where nobody is made to feel excluded because of their immutable characteristics without forcing people to write diversity statements or having Robin Di Angelo types come in to lecture white people about their inherent racism?
