Ethereum

one of unspoken points of rollup centric roadmap endgame is making all rollups highly interoperable, eventually abstracting the entire rollup thing on UX. you’ll be able to interact with all projects on all rollups from any rollup

I think the end goal is to have all user interactions on L2 including on and off ramps.

L3 that unites all the l2s

End game is it scales

Check out taiko. Sounds like endgame to me.

Old idea is back

don't worry about it. it's ok, if things get too out of hand vitalik will tell everyone "Ok can you guys stop trading"

Everybody loses their money except a few early adopters who managed to cash out, like all other Ponzi schemes.

People interacting with the L2/L3's on an infinite scale, burning Gwei and giving it to the stakers in the ETH Project.

That's the goal of it all.

The endgame is that users do not need to know or care which L2 or bridge they are using, it will all be abstracted away into a seamless user experience of 'on Ethereum' I even expect most user experiences to be feeless as account abstraction will allow third parties to cover gas and any bridging needed.

The current situation is indeed very clunky and not a good UX, but the current situation is obviously not the endgame

We're early

The end game should be 0.000000001 dollar transactions

What do you mean by layer 2s and rollups? Do you mean new flashy cryptos coming out basically sequestering investor money from our beloved ethereum stock?

To get everything to work better than Solana for the user

Eth user experience is cancer

There are some interop projects and thoughts about accessing cross rollup state and their basic idea would be to alleviate some of the pains, but one would still need account abstraction to be properly utilized to remove gas requirements. Furthermore dapps would need to integrate which is kind of a long shot. Overall it should get better, but perhaps not for everything and there will be some quirks as even with interop you won't have direct state atomicity for cross layer 2 operations. Asset oriented dapps will have to work in isolation based on the specific network's bridged assets. Unless they go another route which would introduce great latency to synchronize states, but this would break composability.

So to answer your question - the UX might improve depending on your specific usage. Most of the current dApps will remain kinda clunky to use. And the ecosystem is definitely not going back to a single layer any time soon as there is no viable way to scale and optimize execution costs.
