With the increasing number of transactions taking place on decentralized exchanges (DEX) like Uniswap and the emergence of token memes increasing every day, it will certainly be difficult to reduce gas prices on the ETH network. because DEX is an exchange that costs more than CEX, Also, we know the tax system on memes, this is the reason why in ETH drives the increase in gas usage. IMO
We can blame Vitalik and developers for making ETH a "Turing Complete Smart Contracts Platform". They should've separated contract deployment/execution from the main blockchain. In other words, leaving smart contracts off-chain. Now it's too late to do anything about it, especially when ETH is already launched for mainstream use. Changing the network's architecture would require a hard fork. It's yet to be seen whenever validators will approve a fork or outright reject it. Exchanges are now the dominant force of the ETH blockchain with their customers' stake, so they can do anything they want.
It's possible fees will decline in the future, at the cost of a more centralized blockchain network. Most people won't care because they prefer convenience. I guess we'll be left with Ethereum Classic as a decentralized alternative with cheaper gas fees and faster block times. Who knows if it replaces Ethereum (ETH) in the future? Just my thoughts
