All these three problems already solved by non EVM blockchain like sui, solana and so on.
It's not exactly a problem that needs to be solved. Although you can always argue that these two aren't that decentralized, so does any PoS in existence, even ethereum with its pectra upgrade already making things more centralized by increase cap of ETH for validator.
Repeating lies won't make them true, none of this is solved. All of the ones you listed are very centralized.
Actually sometimes it genuinely feels like the same tech wrapped in fresh buzzwords merely to stir up investors. Shardeum looks interesting on paper with the dynamic state sharding idea, but we’ve seen similar claims before. Algorand did come out strong with their PPoS approach, but even they haven’t totally evaded the trade offs. I don’t think the blockchain trilemma is totally addressed by anyone yet. It’s more like teams are just finding better tradeoffs between decentralization, scalability and security rather than genuinely solving it.
Sharding does not solve scalability.
