1/5) ETH is in a race to scale on-chain
Competitors will overtake ETH if it does not deliver on time
Block space is a valuable resource, not exempt from competition
ETH should pay attention or get left behind, scalable blockchains have arrived; I will cover some in this thread

2/5) EGLD has already fully implemented sharding:
The holy trinity; state, execution & data sharding!
All fully interoperable, exactly what ETH was trying to build!
EGLD has already developed much of the technology; now they just need to build up their ecosystem to catch up

3/5) NEAR has also developed sharding:
Fully live now, also beating ETH in the deployment of sharding!
Having also solved the holy trinity with full interoperability
Instead of multiple chains, NEAR is a single chain where blocks are split into parts; this makes it composable

4/5) XTZ has enshrined roll-ups
Utilizing the advantages of roll-ups without the disadvantages of L2s
This means no admin keys & no permissioned elements
Perfectly interoperable & composable, solving the UX problem that has plagued L2s
As all parts are part of a single whole

5/5) With all of this legitimate competition building up
ETH cannot afford to sit on its laurels; it should pivot back to execution sharding!
Especially now that the competition has proven its viability
L2s will not save ETH from this predicament, just as it did not save BTC
