'If someone from the 1950s suddenly appeared today, what would be the most difficult thing to explain to them?'
This is a strange meme. I know plenty of people who were alive during the 1950s. If they are any indication, the most difficult thing to explain is how to use a modern cell phone or smart phone to make a phone call while not accidentally doing anything else with it.
(I recently got my dad what was advertised as a basic, unsmart cell phone. Every time I picked it up, I managed to trigger the voice recognition function.)
I think the other most difficult thing to explain would be certain kinds of humor that have come about since the 50s. I'm not sure how to explain which kinds, though.This entry was originally posted at http://firecat.dreamwidth.org/796039.html, where there are comments.
