Write a letter to Marry : "... I've just returned from the mountains where I tired mountain biking and rafting! Have you or your friends ever tried extreme sports? If not, which of them would you like to try? What do your parents think of such activities?" ( 100-120 word)​

I believe this question asks whether Artificial Intelligence (AI) will replace human interpreters in 20 years. Well, my answer is it won't.

The reason is that language is subjective, it is full of nuances, references, jokes, puns and colloquialisms that no machine is able to grasp and convey in another language at the moment.

If we think of a more distant future, it is possible that technology will replace human interpreters, but it won't be a problem for interpreters specializing in languages which are less widely spoken.
