ETH gas fee is very high, this is what makes investors switch to other networks such as solanan, BSC and TON.
One thing I worry about is that ethereum's popularity will be eroded and abandoned by many investors because of the expensive gas fee. Although currently ethereum's popularity is still high but we don't or if ethereum dev doesn't improve its project, it will likely be replaced by other cheaper networks.
ETH gas seems quite cheap currently. Have you checked the gas price today?

How you claimed that investors have abandoned Ethereum network?
Even if Ethereum network may not be as popular as Solana network or Ton Network nowadays, it doesn't mean Ethereum network is no longer popular among crypto users.
By the way, I personally never think that there is another platform that can replace Ethereum.
