Existential threat to Ethereum

Hey gang. I was wondering what y’all’s opinion on Ethereum dominance going into the future will be? Other layer 1’s such as solana have faster transaction rates/lower fees, yet sacrifice security through lack of decentralization as they have fewer validators. Ethereum sharding will not be introduced until 2023 if we are lucky. Anyway, long term are y’all still bullish on eth as the dominant layer 1 despite the short term migration of developers to other layer 1’s? Still learning , appreciate your thoughts
