When I was a small child, I took an IQ test. One of the first questions I stumbled on was "A piece of candy costs 25¢. Jonny has a dime. How many nickels does he need to buy the candy?"
My 7-year old brain popped. WTAF is a nickel? Or a dime for that matter? We don't have those coins in my country! We don't spend in ¢ either. There was no way to get around the cultural knowledge required by the test. There were several questions like that - all assuming the test maker and taker were from a cultural homogeneity.
A few days ago, I had to complete a CAPTCHA. One of those irritating little web tests which is supposed to prove that you are a human. Here's what I got:
Guess what, Google? Taxis in my country are generally black. I've watched enough movies to know that all of the ones in America are yellow. But in every other country I've visited, taxis have been a mish-mash of different hues.
This annoys me. Will Google's self driving cars simply not recognise London's Black Cabs? Will any yellow car in the UK be classified as a taxi by the infallible algorithm? Will Google refuse to believe I'm human simply because I don't know what a Twinkie is?
Before sticking a comment below, riddle me this - if something costs a half-a-crown, and you pay with a florin, how many tanners will you get in your change?
