There is a chicken and egg problem. How does one make a secure password manager password...? There still is the need for users to learn how to generate secure but memorizable passwords.
With one big exception. There is only one (not 30 or 50 or 100) to have to remember (the master one) and it is one that someone will have to enter repeatedly (until they decide to change it) so they will eventually have enough practice to actually remember it.
