  438. <p>When the hedge funders asked me the best way to maintain authority over their security forces after “the event,” I suggested that their best bet would be to treat those people really well, right now. They should be engaging with their security staffs as if they were members of their own family. And the more they can expand this ethos of inclusivity to the rest of their business practices, supply chain management, sustainability efforts, and wealth distribution, the less chance there will be of an “event” in the first place. All this technological wizardry could be applied toward less romantic but entirely more collective interests right now.</p>
  439. <p>They were amused by my optimism, but they didn’t really buy it. They were not interested in how to avoid a calamity; they’re convinced we are too far gone. For all their wealth and power, they don’t believe they can affect the future.</p>

  442. <p>And they are right, you cannot buy that. You can influence at a bigger scale with your exemplarity though.</p>
