Ironically, I think the GP meant exactly what google translate translated, and that your interpretation is wrong. He says that it takes him a long time to translate French and he won't even start if the original text is Chinese or Japanese. :) Edit: check replies below
I am native French, I need concentration to understand the intent on any xyz to French Google translations. A good proof is to translate back and forth a text. I often use German to English or Japanese to English (amazon), I can guess the overall meaning but 60% is my own interpretation.
I'd like to say it proves we're not general intelligences most of the time, but let's not generalize: it only proves that I am not a general intelligence most of the times. :)
