Understandably, the rhetoric is still entirely monolithic blockchain (L1) centric, presumably a reflection of people's bags - they don't want progress.
The real question is which projects are best specialized in these categories?
- Execution
- Settlement
- Data availability

I generally stick to talking about the specialized execution layers, i.e. rollups/validiums/volitions, but the truth is all three are interlinked and as long as people continue to have monolithic-centric biases the discussion is stifled. Let's start thinking in E, S and DA terms.

Example of why monolithic/L1-centric thinking is plain wrong. E, S and DA can be different. The correct comparisons should be E vs E, S vs S, DA vs DA; not L1 vs L1.

Example 2: with a volition execution layer, it can have multiple DA options, leading to a single execution layer that can replicate the properties and trade-offs of all L1s - except far more efficiently. So the "L1 vs L1" thoughts are totally irrelevant.

Additional note: the term "L2" is also a vestige of monolithic-centric perspectives.
Old: L1, L2
New: E, S, DA
Users will exclusively use E layers, while S & DA layers will be infrastructural under-the-hood. Depending on the scenario, S is also a monetary/economic layer.
