Even that is IMO untrue: "technical solutions" have indeed changed society at large quite significantly; eg. "social media" is one very influential example, "smart phone" is another, "internet" itself, etc.

Aren't you agreeing with me? None of those things changed the underlying social dynamics that humans exhibit but they nonetheless affected widespread social and political change.

We might have different definitions of "social dynamics": to me, it is a marked change when people tune to impress strangers on "social media", vs building their "standing" with peers and neighbours.
