I get that as a VC you have a deeply emotional attachment to encouraging people not to resort to violence, but your energies are best directed toward your fellow tech elite to encourage to stop doing things that are leading millions of people to contemplate violence against them.

All the jets in the world won't stop the violence once that bridge is crossed. Because the mob also has access to jets, and boats, and (at that point) an emotional reason to pursue their targets to the ends of the earth.

Ish. Most survived. And they didn’t have jets.

You have a very VC/tech-bro/Theranosesque definition of "most survived". More than 2/3rds of the French aristocracy was killed in the French Revolution. Even the low bound using just the official numbers puts almost half of the aristocrats having been executed or died in prison during the French Revolution.

Revolutions today are broadly accretive for elites.

They aren't, unless you're referring to the weapons dealers, warlords, or the complicit. Revolutions tend to have outsized impacts on reducing the wealth of elites. The only exceptions are where the elites were part of the security apparatus on the side that won the conflict and gained their wealth by murdering the people who had what they wanted. The inevitable result though is that when they lose that power, they tend to lose their lives (see e.g., Syria and South Africa).
