But users have to understand the risks [inherent in driving a killing
machine such as a car, or sending sensitive data over any one
transport].
I believe users need to know, and be educated if need be, about scams
(e.g., phishing) and how to recognize when they are at risk. Some
details necessarily bleed through the abstractions ("cars burn gas").
When I tried out the padlock analogy last yesterday, my audience got the
MITM problem mainly when I mentioned relying on 411 as an online
directory. Finding analogies that make real risks evident to the
uninitiated is important, provided we can find such analogies of course.
