I think that miners also have a role to play in all these, and hence the reason Ethereum team are trying their best to ensure all these issues like gas fee and speed are taken care of in the next upgrade.
However, every upgrade done by a team on their platform have a specific function or reason for that upgrade, some might be strictly for security, some for speed, some for more user-friendly interface and so on, in the case of Ethereum, the London hard fork was done in order to reduce the circulating supply of ETH, hence in every transaction ETH coin is burnt; thus it can be seen that the London hard fork have no business with gas fees but we should wait for the ETH 2.0.
Also, the last time this fees was this high was months ago, during the bull run, that is, the more the ETH price increases, the more the value of gas fees increases, nevertheless the team have understood that more growth of Ethereum blockchain depends on their ability to solve this issue.
