We are all building the same thing: infinite, dynamically & horizontally scalable blockspace

(d)Apps can choose within the sovereignty vs composability spectrum. Fees are infinite dimensional, enabling infinite number of "composability domains" (apps that compose).

- If an app needs no composability, it will have an independent fee market that is free from global congestion.
- If a group of apps need composability amongst each other, they will share a fee market.

The two popular scaling & interop approaches today can achieve dynamic horizontal scaling:

1. Coordinated sequencers + shared settlement (+ ephemeral rollups) can get us there.
2. True parallelization + local fee markets on a single chain can also potentially get us there.

There are of course lots challenges that I swept underneath the rug here, such as the need for horizontally scalable DA, as well as a new smart contract framework that fits the entire trade-off spectrum for apps (existing VMs are not designed for this).
