> (2) Silicon Valley is becoming less tolerant of divergent viewpoints.As measured by what? Are there people being jailed for expressing a divergent opinion, or being refused service in restaurants/hotels/shops/etc, or unable to find employment?
For the latter point, employment, some people are likely to pick one of the few examples that routinely get reused in this discussion - such as Damore + Google, or Eich + Mozilla. But are these kind of things actually happening at an increasing rate? Because I recall similar things happening in the 2000s, and 90s, and I wasn't around before but they likely did too (and go back a few decades earlier, and it'd be saying something like "women can be engineers just like men" or "black people can be doctors just like white people" that'd get you ostracized, so yeah). So unless you have actual data showing that there has been an increase in people getting fired/being denied employment in the past 5-10 years for having divergent viewpoints, there's nothing there.
If your main measure for "less tolerant of divergent viewpoints" is "people being mean to you on Twitter", well yeah, that's part of living in an open society. In fact one could equally argue that people feeling more empowered to call out things they disagree with is the very hallmark of an open society.
