I keep hearing this argument but I really don't buy it, sorry. I think that over time these other chains are also going to naturally decentralize, at least in the case of Solana the primary barrier of entry is hardware. I think that actually having a product that works today is more important than a platform that hasn't been scalable since inception. Maybe ETH 2.0 will release sometime and all the ongoing scalability efforts actually do work, but until then I think it's absurd to write off other chains that are vastly outperforming it.
Edit -
It's really, really easy to see that a transaction on Ethereum is not even remotely worth the gas it charges today. I remember hearing ETH people trashing BTC transaction prices in 2017, but yeah I'm sorry, this is so beyond absurd I cannot support or recommend anyone use ETH as a layer 1 until it is actually a scalable chain. Not in theory, but actually works. Wasn't sharding and layering discussed in 2017? How much longer until it's actually usable? Gas price for minting a JPG the other day for me would have been $300. This isn't worth it in any world unless you are sitting on a fat stack of ETH you bought under $200. But then you should just sell it instead of actually using it. Don't you see the problem? Why do you think there's so many articles talking about how terrible Web3 is? It couldn't possibly be that people's first impression of the tech is on a financially impractical chain.
I like working in Solidity and think the EVM is great, and there's a lot of cool projects in the Ethereum ecosystem. But ETH is an unusable L1 for the vast majority of people until they solve scalability. No amount of decentralization dreams are worth it. Hell, you could even just use Ethereum classic if you wanted. It does everything ETH does because it's just ETH except they didn't have a centralized Ethereum foundation mutate the chain history because someone stole a bunch of money from them and only costs like $50 the last time I checked. If you care so much about decentralization shouldn't you like the chain that didn't have it's history changed by a centralized organization?
If you really want the most decentralized network possible, Bitcoin is it. I haven't looked into the taproot update too much yet, but maybe it'll be actually supported before ETH scales at this rate.
