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.
