What is the end game for Ethereum scalling?

Anyone else hate how much layer 2s and rollups split up the attention of the eth ecosystem? It is terrible user experience to have to bridge from one chain to another if you want to use a new dapp that is only available on a chain where you don't have funds, the liquidity of the dapps also suffer, cause it is now split all over the l2s, and rollups.

Is there anything on the roadmap that eventually puts everything back in a single layer without the assle of having to use bridges, and where every app can actually be composable, etc ? Cause from what I read, scaling ethereum layer 1 with sharding is not in the plans anymore, so what is the end game?
