What's Danksharding and crList, and why are they so groundbreaking?

Danksharding gets the name from the core dev who proposed it, @dankrad. Instead of the previous design which was simply parallel data shards, Danksharding flips Ethereum upside down with a new role: the block builder.
The builder grabs all of the existing L1 data as well as rollup data and puts them together into blocks which are then broadcasted to the network. Since we're giving builders this massive power, there needs to be a check involved to avoid censorship, which is crList.
crList is a way to force builders to include a transaction inside a block, making it censorship resistant. By forcing builders to be honest, the protocol stays trustless.
With this model, L1 and rollup data is in the same spot, allowing rollups to be more interoperable and connected. It flips Ethereum around and turns the L1 execution layer into a piece of the whole, rather than everything running on top of it.
This paves the way towards turning the existing L1 execution layer into a rollup in the future, if desired. With crList, transactions can be pre-confirmed instantly, even before they get introduced into to the block!
As @epolynya put it: "Danksharding turns Ethereum into a unified settlement and data availability layer."
The Endgame is here, on paper. We just have to finish building it.
