Vitalik: Ethereum should prioritize increasing bandwidth rather than pursuing extremely low latency; L2 will play a key role in the long term.

With the help of PeerDAS and ZKP, Ethereum's scalability can be improved by thousands of times without compromising decentralization. Latency, on the other hand, is limited by physical laws and real-world conditions, such as the need to support global home nodes, censorship resistance, and anonymity.
