The network of devices which authenticated each other's keys can be seen as a complete graph with each device as a node and each mutual authentication as an edge. The network of devices which authenticated each other's keys can be seen as a complete graph where each device is a node and each mutual authentication is an edge.
The number of edges grows for each new device by the number of existing nodes. The number of edges grows for each new device by the number of existing nodes.
That means to sustain a secure communication across all devices, a new key has to be authenticated by all n existing devices and vice versa. This is due to the fact that in order to sustain secure channels between all devices, a new key has to be authenticated by all n existing devices and vice versa.

One of those n mutual authentications requires user interaction like scanning each other's QR codes or comparing each other's key identifiers by hand. One of those n mutual authentications requires user interaction like scanning each other's QR code or comparing each other's key identifier by hand.
That is the initial mutual manual authentication. That is the initial mutual manual authentication.
The remaining authentications can be automated relying on the secure channel established by the inital mutual manual authentication and the secure channels already created by the same procedure between the rest of the devices.
