Multi-user coordination is massively underserved in software today.

The reason is that each silo doesn't know about the other.

So each bit of multi-user coordination only works per silo.

To have high-fidelity coordination across the m silos that contain your data with n people is just combinatorially too expensive.

So you fall back on the smallest number of silos that you know everyone uses.

This reduces down to WhatsApp or Google Docs.

In enterprise, higher leverage tools can emerge, because there's a schelling point of the tools that the enterprise requires the employees to use.

But for consumers, it's hopeless to coordinate on anything other than the lowest common denominator.

We are social beings, coordinating in high-fidelity ways should be common and powerful.

But we're missing the Silver Swarm of social software, because the physics of trust make it impossible.

These are the missing social use cases.

You might conclude that they must not be valuable because we don't have them today.

But actually we don't have them today because our physics of trust make them too costly.

New physics of trust that make them cheap will unlock tons of value that was always sitting there, waiting to be activated.
