レッスンを作成中...
1
Since the turn of the century, technology has rapidly improved.
2
Our reality is now filled with things that were mere dreams in the past few decades.
3
Seeing how the past has unfolded, I was curious about what the next 30 years would look like, so I did a little digging into what life might look like in 2050 for us.
4
Let's take a look.
5
Nanotechnology First, let's take a look at nanotechnology.
6
Over the years, scientists have made exciting developments and discovered numerous innovative applications for nanotechnology.
7
As it stands, nanotechnology has the potential to change life as we know it.
8
Experts in the field believe that nanobots will, in the future, be fitted into our brains to connect us to the virtual world more readily and faster.
9
With the use of brain-computer interface technology, the mind and computer will be one,
10
making humans very powerful beings with access to endless information and solutions to problems that the mind wouldn't be able to solve.
11
If nanotechnology reaches that stage, there may be no need for gadgets like phones and calculators.
12
Well, this is very exciting for the student of the future.
13
Looks like math will not be a universal challenge much longer.
14
3D Print Technology The next tech advancement that we can expect in the future is the rise of 3D print technology.
15
3D print technology is already advanced, but we can expect it to be even more advanced in 2050.
16
Right now, we have 3D printed tools and homes.
17
In the future, we will be able to print more tools
18
and perhaps even some modes of transportation if bigger machines are built.
19
This technology will also become more accessible to everyone who may want a 3D printer, making the possibilities of what can be printed infinite.
20
If the current trend of open source 3D printable files continues, it will not be long before everyone prints their own large objects like furniture and weapons.
21
Well, here's an idea.
22
How about developing an affordable 3D printer for food?
23
That could be the end of world hunger, despite global warming.
24
Medical Now we go from the extinction of phones to the eradication of death.
25
Well by 2050, the finality of death may be a thing of the past.
26
With the brain connected to a computer through BCI technology, the information stored in our brains can be transferred into a hard disk, like computer files.
27
That means the data, including memories, can be retrieved and uploaded into another being, maybe a more advanced humanoid robot.
28
This way, the best minds in every field will be preserved and able to continue working on innovations.
29
Another improvement to consider in the medical field is that serious diseases like cancer will be cured.
30
The only downside to this development is that every new technology is very expensive when it first comes out,
31
so the rest of us may not have access to this literally life-saving technology for a while.
32
Transportation Something that we may have access to is transportation.
33
In 2050, transportation will have immensely changed.
34
With experimentation focused on self-driving cars already underway from car manufacturers such as Tesla, it is not much of a stretch to believe that by 2050,
35
the technology for fully automated vehicles will exist.
36
Some notable advantages of such automated vehicles include a drastic reduction in traffic-related deaths
37
because the vehicles will collaborate with traffic control systems.
38
Another advantage is the change in lifestyle that self-driving vehicles will bring.
39
With no need to man a vehicle, people will be free to choose whether to relax or be more productive as they travel.
40
A lot of free time, considering the amount of time spent in traffic.
41
Another interesting development is the Hyperloop One project by Elon, which aims to move the bulk of public transportation underground.
42
With the use of electromagnetic levitation at historic speeds of 310 km per hour, this train presents the opportunity for a faster,
43
cheaper and cleaner mode of transportation.
44
And if more people opt for it, then there will be even fewer traffic-related incidents.
45
Fuel Still on transportation, the fuel used in all future transportation modes will be renewable Currently,
46
the world is plagued by global warming and the threat of depleting natural resources, so we do need to be looking at adapting to a more sustainable source of energy.
47
Now, Hyperloop One is exploring electromagnetic levitation, and the automobile industry has also been looking for ways to reduce harmful vehicle emissions.
48
These are all efforts aimed at achieving the goal of stopping the use of carbon-emitting fuels.
49
Besides those, research is being done on the ocean's wind, solar, and thermal energy.
50
One company in particular, BlueRise, a specialist developer of ocean thermal energy conversion, is working on a project that could completely phase out the use of fossil fuels.
51
Hopefully, BlueRise and their colleagues will be successful soon enough to alleviate some of the environmental problems we face.
52
Space exploration Now, if there is one thing that has been mentioned as a mitigating option for our current environmental challenges, it's space exploration and colonization.
53
Companies like SpaceX and Blue Origin are set on revolutionizing space technology,
54
with goals of spatial exploration and ultimately enabling people to live on other planets in colonies.
55
With all the strides already made, by 2050 space tourism will also be a reality for those who can afford it.
56
The possibilities for holiday destinations will expand to include places like Mars and the Moon.
57
Unfortunately, a trip to orbit will be significantly expensive, making it exclusive for the extremely wealthy, at least at first.
58
Artificial Intelligence Something that may be available for everyone is artificial intelligence.
59
Already more advanced than most of the innovations mentioned here, the development of artificial intelligence will only get better through the years.
60
Experts in the field believe that AI will surpass the processing power of living brains.
61
That wouldn't be scary if it didn't open the door to the robo-pocalypse.
62
Luckily, scientists still have to figure out how to impart all
63
the important human values into an AI before it can become a part of our everyday life.
64
But the rise of AI will, of course, change the face of the workforce.
65
Not only that, but the job market will also face radical change, and with the way things are going, about half of the world's current jobs will be extinct,
66
taken over by AI machines and robots.
67
In 2050, the world will be more interconnected and even more driven by data than it is now.
68
Some of us will definitely need to consider a career change.
69
Education As the job market changes, education will also see some significant changes.
70
Already there has been an increase in digital learning, especially during the pandemic.
71
By 2050, completely digital schools will be commonplace.
72
Even if we have physically attended schools, they will have no need for books, using tablets and laptops instead.
73
For higher education, experts believe that more than 70% of the student population will be enrolled in online degrees, making education more globalized.
74
A rather welcome step in the right direction if we are to make good education accessible to all, I believe.
75
Online degrees may even be taught by AI-powered robots.
76
At that time, I imagine the robots will be able to prepare course material, give lectures, and mark assignments.
77
Sadly, you may be unable to twist your lecturer's arm so they give you a deadline extension.
78
The Metaverse Now, we move on to the Metaverse.
79
Since Facebook CEO Mark Zuckerberg announced it, virtual reality and AI have been assimilated into our everyday life through the social media giant.
80
For those who may be a bit confused about the metaverse, you're not alone and you've come to the right place.
81
The metaverse is a virtual reality computer generated environment in which you can interact with other users through AI enabled software.
82
So it's about simulation with avatars representing users.
83
As metaverse functions get more developed, by 2050 it will be able to offer a full virtual experience
84
that includes shopping to travel right from the comfort of your own home.
85
People will have the option to share their virtual experiences with the world.
86
Imagine taking a trip to your favorite holiday destination with your family, only you're not physically there.
87
That's what the metaverse will offer.
88
It seems to me like the more we get connected, the more we stay apart.
89
Money.
90
Next is money.
91
Even though we will still use money, one thing that has been used less and less over the years is cash.
92
Keeping up with that trend, cash will most likely no longer be used in 2050.
93
All transactions will be done virtually, and new modes of financial transactions will emerge because of AI and decentralized finance.
94
As the world slowly starts to adopt those technologies, we may not even have to do our own grocery shopping anymore, making traditional paper and plastic money even less useful.
95
Like Tesla, which orders its own car parts as needed, our automated pantries and refrigerators may order our groceries.
96
No more getting the wrong milk, or even running out of milk.
97
Real Estate Speaking of the automation of home appliances, the homes in 2050 will also be completely automated smart homes.
98
Although smart homes already exist, the developments that will be available in the next few decades will be a great improvement to what we have now.
99
Smart homes in 2050 will have full AI activation functions, allowing the home to sense our moods and requirements without giving it a single command.
100
Additionally, interactive hologram televisions will exist, meaning that you can verbally call up your hologram TV And it will appear right in front of you.
101
The best part?
102
You will never have to look for the remote again, because you can control the TV with your mind using nanotechnology as discussed at the beginning of the video.
103
So with that we have come full circle in this video of exploring what our lives will look like in 2050.
104
To be honest, this is just an exercise of imagination, and I realized that not everything discussed in this video will come true.
105
However, you'd have to agree
106
that none of this is too far-fetched either as humanity has already planted the roots of many of these technologies Anyways,
107
one thing is for certain with how technology is progressing I have no doubt
108
that the world will be very different by 2050
109
But I do hope that our current societal systems
110
and structures will be able to cope with these coming innovations So what do you think of these future innovations?
111
Do you think this is what life will look like in 2050?

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
