According to Vitalik Buterin, Ethereum has seen significant improvements. Transaction fees on Layer 2 (L2) solutions are now below $0.01. Two Ethereum Virtual Machine (EVM) L2s, Optimism and Arbitrum, have reached stage 1. The user experience for cross-L2 wallets has greatly improved, eliminating the need for manual network switching. Additionally, Zero-Knowledge (ZK) tooling has become more powerful and mature, enhancing the overall ecosystem.
