Well, uh, I am pretty sure you are wrong.
People are social animals and not technophiles. Most of the behaviors associated with technophiles are distinctly anti-social and this comes from a variety of sources. For example, for every one source in popular media that extolls the wonderfulness of a technophile, there are 10 that make the technophile out to be the stereotypical nerd and an object of derision.
Who wakes up in the morning with the thought in their head "I want to be less likeable and more an object of derision." Nope, sorry, technical abilities and skills are a passing fad.
What is going to happen, clearly, is that the technical requirements - especially very picky detail-oriented ones - are going to all but disappear. Complex passwords, password vaults, using lots and lots of different passwords, etc. are all going to disappear. The reason is simple, it would take someone that would be easily classed as a "nerd" to manage such a life and people intensely do not want to be nerds nor thought of as nerds.
What we will do is to simplify the whole problem. How about a bracelet that reads biometric data (to insure it is worn by its owner) and is your "passphrase". If you take it off, it has to be reset so it cannot be stolen. It probably should not use any protocol that can be intercepted. It can be an extremely complicated device but the key is that it is simple to use - you just stick the bracelet in a loop that reads it and it works for everything.
OK, maybe we have implantable chips instead. Or a badge that runs off body heat. Something. It can be a pretty expensive device because the alternative is getting left out of everything or having stuff stolen. It should clearly be something that cannot be stolen and reused, and obviously it should be something that is very, very difficult to lose.
OK, think up some nerd-proof device that the average Joe can use, never lose and isn't subject to being stolen and being reused. I'm sure it is possible and if the interface to read it is cheap enough we can start with putting one on every PC and every ATM. Then use it for credit card data and get rid of all the cards. Because it IS in fact your identity it can also replace a driver license and likely replace a passport as well.
Trust me, nobody is going to want to walk up to an ATM and look up the proper 17-digit PIN on their phone password keeper. Moreover, they will not do it. Something else will happen.
