the worst conventional wisdom in crypto is:

"blockchains will fade into the background and people won't care which one they are using"

(Exhibit A: there were 6 NFT Marketplaces on Terra chain)

I work for Ethereum at the Ethereum Foundation.

That scenario is a *failure* mode for blockchain adoption:

(1) Because "creating a blockchain" is permissionless, the set of all blockchains will always have widely varying security properties

(2) If people can't distinguish between them, they cannot make good choices

People won’t care which ones they are using. Developers will.

I don’t think there’s a universe where we get to mainstream adoption if people have to care about the chain things are on.
