While I'm not going to dive into the debate you're having one way or the other I do want to comment on the following
There won't even be what we consider passwords in the future.
That's never going to happen. Passwords/pins represent one of the three fundamental types of information we use for authentication.
Any one on their own is unsafe which is why we're starting to move to coupling them with one of the others for a two factor authentication. Passwords easily the most useful, and protected, of the three which is why they are the most common form of single factor authentication. Of the other two they are most commonly paired with something you have because it means if either are compromised they can easily be replaced, while your biometrics can't.
That is not something that is going to change and it's unlikely you'll see biometrics used outside of either trivial security, such as unlocking a phone, or extremely high security. In terms of something in the middle ground, like every day corporate logins, however they are, and will, remain much more effort than they are worth.
