I used to know a guy who was pretty high up in the railway industry. Nice guy.
Whenever a new train had gone through R&D he watch these newly designed trains being put through various tests.
There was an agreement with a technical division of the army to help oversee safety tests - which a new design had to pass before being put into service.
He'd watch with some amusement/amazement at one particular part of the tests where the Army Major would call out for, "the little old lady with a tight skirt" who each time helped in the tests.
The test was designed to see whether the weakest, smallest and less equipped person could step inside and use the train.
Trains aren't Bitcoin - sure. There's a lot more to understand and more technology to use.
However, if bitcoin were to be accepted and have mainstream use people need to have an eye out for the less capable amongst us.
Who should be the equivalent in say Bitcoin wallet use, what are the choke-points and how could they be ironed-out on the field?
