A lot of people and Democrats in STEM fields who voted for Kamala in the elections, including pg who publicly stated he was voting for Kamala, thought the corporate DEIA initiatives were counterproductive to their stated goals. It's not a extreme minority position in the tech crowd, nor is there a complete lack of criticism of corporate DEIA in the progressive media either.
I also give pg credit for being one of the rare VCs who posts "pro-Palestinian" viewpoints on occasion. So he does buck the trend from time to time. Calling David Sacks, Musk's unwavering eternal sychophant, possibly "the most evil person in Silicon Valley" was also a great line in the sand for him. But the basis for this opinion was more from his knowledge of how terrible Sacks treated founders as an investor rather than from Sacks being a Musk acolyte.
The people arguing the other side are not talking about reversible mistakes with minor fallout. They are claiming that taken as a whole the damage will be very difficult to undo. Countering this simply by accepting that there will be mistakes doesn't quite suffice. As pg tried to remind Musk on twitter (I'm paraphrasing): Countless startups come into being and die within the system. But this is the system we're talking about. There is only one.
I take it you want the others to believe this administration geniunely cares about providing the public efficient services without fraud and corruption by establishing highly-efficient meritocratic institutions. There's overwhelming evidence in the events of the past few weeks that this not the case. Just looking at the Eric Adams fiasco and, say, the cabinet picks of Hegseth, Gaetz, Bondi (straight of the movie Idiocracy) show this administration does not care about fighting corruption or hiring people that are most qualified for the job.
