Have you ever used a Walkman to listen to music?

Are you still using a typewriter to do your reports?

For many teenagers, the answer is no.

In the past, different technology was used to make people's lives easier.

For example, more than twenty years ago,

beepers were a popular choice for people to get in touch with each other.

Once they noticed their beepers going off,

they would go and find a phone to call the number back.

In the 1990s, beepers were used by millions of people in Taiwan,

but now they are a thing of the past.

Now, more and more people use smartphones instead.

They simply pick up their phones, touch the screens, and talk.

With smartphones, they can also use different forms of social media to reach people.

Without a doubt, smartphones are very popular now.

However, will they still be used to reach others in the future?

Some watches are able to do this now,

so maybe in the near future,

your glasses can do the job, too.
