- More secure (Face ID uses more data points)

- Less user-interaction to authenticate (though as you point out this is also a negative)

- Allows for other UX improvements, e.g., maintaining screen lighting while phone is being observed but not manipulated

- My speculation: capacity to add additional faces will be added with SW (or next HW) update

I don't understand your point #3. How do you think someone would unlock your phone with Face ID?

[Jeremy1026]

For their Point #3 I'm guessing they are saying if they are sleeping or a mugger points their phone at their face. Fortunately, Face ID has focus detection, so if you aren't looking at it then it won't unlock. Which makes point #3 moot as well.

Apple has mitigated this, your eyes need to be open and looking at the screen to be unlocked.

It requires your face + your attention.
