Both Apple and Google have recently announced new features for

their smartphone operating systems that will help users keep track of their

screentime and possibly limit it. While that certainly shows the companies’

willingness to help limit the negative effects of excessive smartphone use,

ultimately, it’s in the consumers’ hands to change their possibly unhealthy

habits.

There are a myriad of predictions, encouraging

and terrifying, about what technological innovations the

future holds. One of these hypotheses is that, sooner rather than later, the

language barrier will effectively be broken thanks to modern language

technology. From Google Translate all the way to simultaneous translation

earbuds, some have predicted new technology will make it unnecessary and,

frankly, impractical to learn a language. Why study French when you can get

along just fine in Paris with a wearable device? How important is

understanding Spanish verb conjugation if your phone does it for you?

Researchers across different studies have

found that studying a language seems to unlock students’ creative abilities.

This could be the result of the thought processes involved in language

learning. These include translation, language switching and disciplined

study, along with a willingness to learn and adapt. Language learning skills

will help learners in all areas of their lives, improving their mental

abilities, and helping them with problem-solving and decision–making.

Ultimately, this all goes towards enriching their personal, social and

professional relationships.

After your talk, please, answer three questions:

1. What other benefits does

language learning have?

2. What advice would you give

to someone learning a language?

3. Why do some people give up

when learning a language?
