Robert Sasu, core developer of MultiversX, in reply to Vitalik's comment on "Encryption enters early stages in terms of L2 cost reduction, ZK-SNARKS, account abstraction", stated that on a truly decentralized network, a centralized sorter can actually be cheap. Rollups based networks are great, like Taiko, but right now that's just a handful. Hopefully more people migrate to Rollups. I think not only should L1 be scaled, this will help eliminate all unwanted L2, the benefits of scaling the base layer are huge.
