Hey @timdaub.eth I just read your "Why I don't believe in a multichain future" piece and I think you approached it from the ETH-native multi-chain PoV. A lot of your criticisms aren't relevant in an actual multi-chain ecosystem like Cosmos.

Security issues are mitigated by opt-in shared security (either one-chain or mesh-network);
Stong composability via smart contracts (EVM, CosmWasm, Hardened Javascript) & ABCI++. 
Cross-chain UX is great via IBC and Interchain accounts. 
Scalability resolved by data-availability sampling.

Sure, that makes sense but that chain is probably going to be irrelevant. 

In reality, the multi-chain future is already here and any chains that are not able to pass light-client verifiable messages to other interconnected chains and don't already have a deep moat can be written off.
