One advantage of modular tech stack like Ethereum is that it attracts Layer 2 developers. Layer 2 developers can make a lot of money. See Base from Coinbase. Therefore, many exchanges like Coinbase(L2 Base), Kraken(L2 Ink), Bybit(L2 Mantle)... are building Layer 2 on Ethereum. They will attract more users, coders, and liquidity to Ethereum. Layers 2s are builders/distributor for Ethereum Network. Who win the distribution problem will probably win the blockchain war.
Maybe one day Robinhood, Stripe, Blackrock, Charles Schwab, Nasdaq... will build a Layer 2 on Ethereum.
Sony already launched an Ethereum L2 called Soneium: https://www.sony.com/en/SonyInfo/News/Press/202501/25-002E/
World(co-founded by Sam Altman ) is also an Ethereum Layer 2.
Deutsche Bank is reportedly creating a layer-2 (L2) blockchain solution on Ethereum using ZKsync technology: https://www.binance.com/en/square/post/12-18-2024-deutsche-bank-develops-layer-2-network-on-ethereum-using-zksync-17746441239850
