Every day, smartphones are getting smarter,

智慧型手機每天都變得更智能，

AI is becoming more intelligent,

人工智慧變得越來越聰明，

and our environment seems to be getting worse every year.

而環境似乎也每年都在惡化。

If you were to travel 50 years into the future, what would the world look like?

如能旅行至 50 年後的將來，世界會是什麼樣子？

Would robots have taken over everything?

機器人已經掌管一切了嗎？

Would we still be living on Earth?

我們還住在地球上嗎？

Would alien life finally be discovered?

終於發現外星生命了嗎？

This is WHAT IF, and here's what would happen if you lived 50 years in the future.

您收看的是大膽科學，接下來將帶您看到人類五十年後的生活。

Look down at your phone and think how far technology has come in the last 10 years.

低頭看看手機，想想近 10 年來科技的蓬勃發展。

Have you ever imagined what tech might look like in 50 years?

是否想像過 50 年後的科技會發展到什麼程度？

What about your family and friends? What will happen to them?

你的家人和朋友呢？他們會發生什麼事？

In 50 years' time, we might actually look back and laugh at how we used to have to hold our phones.

50 年後，人類可能會回顧現在，取笑我們還得用手拿手機。

How primitive!

超原始！

Instead, our smartphones will either be worn or implanted in us through contact lenses.

取而代之，智慧型手機會變成穿戴式或透過隱形眼鏡植入人體。

Imagine being able to have your GPS embedded in your vision, instead of having to look down at your phone.

想像將全球定位系統嵌入視野中，不必低頭看手機的情況。

But, although this all sounds nice, there will be problems, too.

儘管這一切聽起來都很不錯，還是存在問題的。

If you don't want to fast-forward yourself into the future because you're worried that your family might not be around,

如果因為擔心家人可能早已不在，而不想前往未來，

well, you can rest easy, knowing that in 50 years, the average life expectancy will be about 80 to 90 years.

可以放心，因為 50 年後，人類平均壽命將會落在 80 到 90 歲間。

That's over 10 years longer than it is today.

比今日的平均壽命多上 10 歲以上。

Since the nineteen sixties, our population percentages have always looked like a pyramid.

自 1960 年代以來，人口分布圖型總是金字塔形。

But 50 years into the future, that pyramid will look more like a rectangle.

但 50 年後，金字塔會變得更像長方形。

This means that there will be an equal percentage of senior citizens to toddlers.

這表示年長者和嬰孩的比例會相同。

This will have a huge effect on the economy.

這會對經濟造成巨大衝擊。

Grandma and Grandpa will be retiring much later, and when they do, those seniors' homes are going to be packed.

爺爺、奶奶退休時間會變得更晚，退休時養老院也會爆滿。

With more people in the work force, jobs will be harder to find.

隨勞動力的增加，工作會變得更難找。

Just graduated school?

剛從學校畢業？

Expect to live at home with mom and dad a bit longer.

預計得多和爸媽住幾年了。

Especially since AI is expected to be working over 800 million of our former jobs by 2030.

尤其因為 2030 年時，人工智能估計將取代約 8 億個職務。

The world's population will be at an all-time high.

世界人口量也將創下新高。

By this time, the population of Earth will have reached a staggering nine billion people.

到那時候，地球人口將驚人的達到 90 億。

More people means more problems.

更多人口意味著會有更多問題。

There will be a much higher probability of food shortages as we try to grow crops to feed everyone.

當我們試圖種植作物來養活所有人，糧食短缺的可能性將大幅增加。

Due to increasing temperatures, crops will be harder to grow as well.

由於氣溫不斷升高，農作物也將變得更難以生長。

And with 70% of the world's population living in cities, crowding will lead to more diseases being spread, and being spread faster.

而當全世界 70％ 的人口都居住在城市中，擁擠將導致更多疾病傳播，加快傳播速度。

As for the environment, well, that doesn't look too good, either.

而在環境面，前景也不太樂觀。

The Amazon rainforest will continue to be deforested, and in 50 years' time, half of it will be gone.

亞馬遜雨林將繼續被砍伐，50 年後，一半面積將完全消失。

Don't expect it to come back, either.

也別指望雨林能恢復了。

Increasing climate change will render it a parched shrubland.

加劇的氣候變遷將使其變成一片乾旱的灌木叢。

Higher temperatures will cause the polar ice caps to melt to less than 50% of what they are today.

高溫將導致極地冰蓋融化，面積不及今日的 50％。

And the Dead Sea may actually live up to its name, as its water will continue to evaporate.

死海或許終究會名副其實，因為其水分將繼續蒸發。

Thinking about visiting American cities like New Orleans, Miami, and Houston?

想造訪美國像是紐奧良、邁阿密和休士頓之類的城市嗎？

Well, sorry, but you're out of luck.

很抱歉，無法如願以償了。

Hurricanes will get a lot worse in the next 50 years, and higher water levels will lead us to abandon the Gulf Coast.

颶風將在未來的 50 年加劇，而高水位會讓人類不得不撤離墨西哥灣區。

But don't worry, it's not all bad.

但別擔心，不全都是壞消息。

Although the world may be dying, it's not the only place humans will have to live.

儘管世界面臨死亡，但地球不再是人類必須居住的唯一地方。

In the next 50 years, humans will have begun colonizing Mars.

在接下來的 50 年，人類將開始殖民火星上。

Private companies will even be attempting to travel to the Alpha Centauri system, the closest star system to our Solar System.

私人公司甚至將嘗試探索半人馬座星系，距太陽系最近的恆星系。

While we're there, we'll visit the Proxima-centauri B planet, which has a good chance of housing alien life.

在那，人類還將造訪比鄰星 b，那裡可能孕育著外星生命。

If we don't find any little green men, we might decide to colonize it ourselves.

如果沒發現任何外星人，我們可能會決定自己殖民它。

So, we've talked about the human race and the environment, but what about you?

好了，已經談了人類和環境，但是你自身呢？

What's going to happen with you 50 years into the future?

50 年後的你會發生什麼事？

Well, first off, you won't have to go to the doctor for your annual checkup.

首先，你不必再去醫院做年度健康檢查了。

You'll have a device where you can scan yourself for any diseases.

你將擁有一部可掃描自己是否患病的設備。

Watch for body modifications to rise in popularity.

等著看吧，人體改造會流行起來。

And, no, we're not talking about tattoos or piercings.

不是在說刺青或穿環。

You'll be able to get things like cybernetic eyes that will allow you to see better and to see things that are invisible to us today, like radiation.

你可以裝機械眼之類的東西，讓你看得更清楚，看到人現今看不見的東西，如輻射。

If you're rich from your Bitcoin investment blowing up, then you can even get yourself a designer baby.

如果你因比特幣投資成為暴發戶，甚至可以買訂製嬰兒。

These babies can be completely customized from simply what they look like to things like their behavior and intelligence.

這些嬰兒可以完全客製，從簡單的外貌到他們的行為和智力。

AI will be as smart as humans.

人工智慧將會和人類一樣聰明。

They won't have taken over the world just yet, but they'll be well on their way.

它們還不會統治世界，但快了。

AI will constantly be progressing in intelligence, soon being smarter than humans could ever imagine ourselves.

人工智慧在智力上會不斷進步，很快就會達到人類無法想像的地步。

Expect them to be working with us, while humans have more advanced roles in our jobs.

可以預計 AI 會與人類共事，而人類則在職場擔任更高階的角色。

So, are you ready for all the good and bad that comes with the future?

那麼，準備好迎接未來所有的好與壞了嗎？

If not, that's okay!

如果還沒，也沒關係！

Just live in the present, and slowly grow into it over the next 50 years.

活在當下，並在未來 50 年中慢慢成長適應也行。

Who knows? In the future, we may not even talk about hypothetical scenarios anymore.

誰知道呢？未來我們甚至可能不再談論假設性情景了。

Will there be any "What ifs"?

未來還會有所謂的「如果」嗎？

Or will every idea in the universe have already gone through a computer simulation?

還是說，宇宙中每個想法都會已經由電腦模擬過了？

That sounds like a question for another What IF.

這聽起來又是另一集大膽科學的好主題了。
