#BZZ Ether is like running a hotel, and now it's fully booked. You can either expand on the spot, which is the swarm solution, or allocate to the nearby small inns, which is the layer-2 solution.

Swarm is the scaling solution proposed first by Vitalik Buterin, and it is clear that Vitalik prefers the later layer-2 solutions.
As the swarm solution matures, the failure of the layer-2 solution will take many years.

When the Layer 2 solution is announced as a failure, it will be the moment of glory for the swarm ecosystem, and bzz will definitely reach 1000U each.
