Ethereum's rising complexity, particularly regarding gas fees and scalability challenges before full upgrades, could hinder everyday user adoption, but Layer 2 solutions like Arbitrum and Optimism help. Solana and Base, on the other hand, provide speed and low fees.
Ethereum's strong network effects and developer ecosystem are significant advantages; prolonged complexity could indeed impact its long-term dominance as the primary blockchain if user experience remains a barrier. Its dominance could shrink, but it's unlikely to vanish entirely.
