Vitalik: Even in an L2-dominated Ethereum, the L1 gas limit needs to be increased

ChainCatcher message, Ethereum co-founder Vitalik Buterin published a new article titled "Reasons to Increase L1 Gas Limit Even in an L2 Dominated Ethereum." The article states that an important recent discussion in the Ethereum roadmap is about how to increase the L1 gas limit.

Recently, the L1 gas limit was increased from 30 million to 36 million, a 20% increase in capacity. Many support a further significant increase in the near future. These increases are considered safe due to recent and upcoming technological improvements: enhanced efficiency of Ethereum clients, reduced need for storing old history due to EIP-4444 (see roadmap), and future stateless clients.

However, before we go down this path, it is important to ask a question: In the context of a Rollup-centric roadmap, is it the right approach to increase the L1 gas limit in the long term? We do not want to face the centralization risks brought by high L1 usage without truly determining that we will benefit from it.
