Create voluntary overlay networks and software on top of existing systems. Once the overlays are sufficiently matured, you won't notice when the foundation they were built on top of dissolves or you actively Exit it entirely.

Imagine taking a complicated clay sculpture and sticking little motion-capture-style nodes in it and wrapping wires on those nodes, etc. at first your wire sculpture would be inaccurate and coarse, but if you add more nodes and wires, bringing up the fidelity of your wire overlay, eventually you'd be able to melt the clay out and still have an accurate representation in your wire armature.

This is what we'll do; pemissionlessly and therefore unstoppably.
