I had an interesting conversation on the plane last week with a retired choir director/professor who had recently experienced fraudulent charges on his bank account. As I had disclosed my profession, he wanted to know how this could have happened and I struggled to answer the question in a way the he - a non-techie - could easily understand.
The conversation made me wonder once again: what should/can we reasonably expect the average person to understand? Do we really need to reduce to the lowest common denominator, or do we at some point draw a line, with the caveat that a certain percent of the population will never "get it"? If so, what percent is reasonable and appropriate?
