I think with Eth2 we're possibly seeing a the first attempt to address the Innovator's Dilemma[0] in the blockchain environment.
I've been following the Eth2 progress for a few months now and from the outside it really feels like trying to swap out the engine of a running racecar.
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.
