We need stupid people to use Bitcoin, just like how they will use iWatch.
It is more likely, and being implemented now, that the service providers will make it a swipe/scan and pin option the same and therefore with approximately equal security as traditional cards . Xapo has already implemented this for their bitcoin loaded card..They also allege that their wallets/vaults are insured I do not know the terms of that insurance but it is likely that it would be = or better to standard FDIC insurance on bank accounts.This allows them to concentrate on the benefits of bitcoin in order to increase adoption while removing the likely critisism that it would be less secure than traditional fiat cards and accounts.
So you say that bitcoin is for tech savvy people?

Bitcoin will follow a similar path...How do I use it..is it safe is it easy to use for the things I want to do with it..what does it cost to use?
After that , how its done is not particularly interesting to the average consumer.
