Ethereum's differentiator (aka what makes it a valuable thing in the world) is that it's a maximally secure/neutral/global base layer
the roadmaps for scaling, UX, hardness, and security are all in service of this
L2s use this secure base layer to provide their own zones of differentiation and control on top (creating their own valuable economies)
and this reinforces Ethereum's unique position as the global neutral base layer
1/ How L1 and L2s can build the strongest possible Ethereum
tldr: we should continue to lean into the unique capabilities of each layer, and make sure all users have a clear path to securely and seamlessly benefit from the core properties of Ethereum
