Google has broken my roman numeral captcha

Maverick Woo sent me an email to let me know that Google does roman numeral arithmetic. I can’t help but imagine the discussion between between the Google engineer and his boss:

  • (Engineer) Hi boss! I plan a new feature for our search engine… roman numeral arithmetic!
  • (Harvard MBA) What a great idea! (Thinking to himself: I need to replace this guy.)

As a basis for comparison, it seems that Yahoo! does not have this feature.

Beside my blog’s captcha, where else do you ever use roman numerals?
