@Jake Van Clief Last thing then I need to go study! lol but this feels worth sharing here. I asked claude the other night about the history of the nervous system, reactivity, and our current experience with it. The last paragraph: "For the “solve at scale” instinct: notice that almost every existing intervention is individual — teach people to regulate (breathwork, vagal tone, interoception, CBT, somatic work). But if this is fundamentally a mismatch problem, then the environment is also a lever, and a strangely neglected one. We’ve spent a few hundred years engineering out physical threats while accidentally engineering in a dense field of symbolic ones — feeds designed to trip threat-detection, status legible at planetary scale, ambient precarity that pings survival circuits without any tiger present. The interesting question your framing opens isn’t only “how do individuals regulate a miscalibrated system,” but “what would environments designed around our actual threat-physiology look like.” That second question is wide open."
