> Passkeys are a fantastic technology. Since they are bound to the site they are created for, they cannot be phished by a hacker’s fake login screen.

The same is true for passwords with a password manager.

> If a site suffers a data breach, passkeys are asymmetric and cannot be recovered from the server-side details.

Also not really a problem with randomly generated site-specific passwords in a password manager.

Really all the browser vendors had to do was add an API to make automatically generate a password that is then stored in the user's password manager the low friction option.

If you're doing that you might as well use public/private keys. The issues with passkeys are around user experience and education about how they are stored, and a lack of good backup options like enrolling a not-present device as opposed to relying on syncing them through an external service.
