Exactly, Vitalik Buterin will never solve this problem because currently the transaction fee problem on Ethereum is no longer possible to fix because it requires large costs and takes quite a long time. Meanwhile, Ethereum is a digital currency that has a high daily trading volume. It's quite high so it's impossible to stop its circulation just to fix high transaction costs and it's also not guaranteed to be successful.
You don't need to stop trading when you have a hard fork, Bitcoin didn't stop trading with Segwit or Taproot either!
Also, there are no high costs, it costs nothing to implement a change, just look at how Bitcoin did these, you just update and the chain continues on the updated protocol, validating new rules.
The problem with Ethereum is simple, Vitalik thinks that eventually his path will lead to scalability, and he refuses other updates that would fix the problem now, much like Bitcoin developers do, so it's more about pride than money!
Yes, that's right, upgrade after upgrade without any noticeable improvement on the Ethereum network. Many upgrades were launched about two years ago until now, the most recent of which was the Dencun upgrade, which promised to significantly reduce fees, but we have not noticed this until now
A long time ago I stopped caring about the eth upgrades.
There was an interesting one when they switched from PoW to PoS but the rest are like Windows updates.
