so

passkey wallets don't solve the seed phrase problem

they just rename concepts. Now Apple, 1Password, etc is backing up your "seed phrase"

fundamentally the only people who have eliminated seed phrases are the zk folks who built wallets that can operate on zkp's of other identities

What do you define as the seed phrase problem? in my mind, the "problem" was:
1. A phrase that you have to back up, manually save etc
2. A single point of failure if you lose it

Passkeys address 1 with built in passkey managers, and address 2 to some extent with automatic syncing across devices etc.

re: single point of failure -- SCW's with multiple signers is interesting, but you have the same recursive problem. 

Ok, I lost a key. I grab another one. I lost that one 💀 You're still "custodying" some seed phrase, passkey, or other material to enable interacting with these wallets

ZK tries to solve this

Submit a transaction containing a ZKP that you custody your email address

great, now all you need is your email, which is tablestakes for literally every other thing you do in life

nothing to remember, nothing to lose

main issue is performance (O(minutes) for proof generation). If they can fix that though...
