https://ethereum.org/en/eth2/vision/ for those who like me need an explainer what Eth2 is.
Definitely worth to follow how the Eth1->Eth2 evolution will play out, but I wonder if is not too late for Ethereum while newer kids on the block [1], much more agile due to lack of legacy overhead, have already launched solutions for many of the problems (PoS, sharding, scarcity, WASM smart contract infra, super-high TPS etc.)[2] that Ethereum will be trying to...in the next year or so.

The vast majority of projects out there are pure speculations and a decent scan through their blog posts, whitepapers and activity on their public repos should be enough to decide if they're building something meaningful (and worth to follow long term) or not.
This is interesting. Cross-shard attacks were a major flaw in shard designs. How is this solved exactly and who is "us" in this sentence? How can the network force a miner/validator to use a specific random shard?
