According to Odaily Planet Daily, Vitalik Buterin wrote that L2 is a cultural extension of Ethereum. He pointed out that Ethereum is an L2-centered ecosystem that can freely and independently build a sub-ecosystem with unique functions, which is also part of the larger Ethereum. L2 can and does achieve some specific ways of cultural specialization, including being more willing to conduct user expansion or "business expansion", emphasizing the diversity of values, and the diversity of participants.
