0:00.00 – 0:17.23 (17.2s)

That was in 2001.

0:17.46 – 0:18.86 (1.4s)

And he said that we’re holding a golden ticket to job security.

0:19.66 – 0:24.06 (4.4s)

Just last month, the CEO of GitHub said that the future of programming is natural language.

0:24.86 – 0:32.43 (7.6s)

It looks like the prediction of my professor at the turn of the century is going to become true, but probably not in the way that he had imagined.

0:34.00 – 0:42.36 (8.4s)

Artificial intelligence is capable of writing code for you through a natural language prompt.

0:43.20 – 0:48.90 (5.7s)

GitHub Copilot can complete code for you and fix bugs for you.

0:49.26 – 0:54.23 (5.0s)

And ChatGPT can create an entire project for you within seconds.

0:54.66 – 0:59.40 (4.7s)

And all these tools are available to anyone.

0:59.93 – 1:02.76 (2.8s)

So I find myself wondering, have we lost our golden tickets to job security?

1:03.66 – 1:08.63 (5.0s)

And as a CSTU professor and a father to a daughter who studied Computer Science, there's a bigger question for me.

1:09.63 – 1:17.90 (8.3s)

If AI is going to do programming, is it still worth it for us to learn software engineering anymore?

1:18.60 – 1:25.10 (6.5s)

Today, I would like to explore this question with all of you guys.

1:26.70 – 1:30.26 (3.6s)

Let’s talk about what AI can do and more importantly, how our students of software engineering can prepare for the future roles of a real software engineer.

1:30.43 – 1:41.76 (11.3s)

So let’s dive in.

1:42.20 – 1:43.33 (1.1s)

First, let’s talk about what AI is good at.

1:43.76 – 1:46.43 (2.7s)

In terms of programming, AI is really good at generating thousands of lines of code.

1:47.70 – 1:53.40 (5.7s)

It translates between programming languages.

1:53.70 – 1:56.20 (2.5s)

It can create user interfaces and fix bugs for you.

1:56.40 – 2:01.23 (4.8s)

And it excels at repetitive tasks, and, you know, pattern recognition.

2:02.06 – 2:06.96 (4.9s)

You know, once I asked ChatGPT to create a project for me, a dating app like Tinder in Python.

2:07.93 – 2:14.70 (6.8s)

And within seconds it actually created a complete application with user profiles, the swiping logic, and even a sample database.

2:15.30 – 2:24.16 (8.9s)

The only thing it didn't do for me is find me a date.

2:24.83 – 2:27.90 (3.1s)

(Laughs) But AI has a lot of limitations. We have to accept that.

2:28.36 – 2:33.56 (5.2s)

It still doesn’t understand the why behind all the tasks we ask them to do.

2:33.73 – 2:37.83 (4.1s)

It needs your human input for real-world context and scenarios.

2:38.16 – 2:44.23 (6.1s)

It may not work well, prioritizing long-term business goals and assessing trade-offs.

2:44.73 – 2:50.66 (5.9s)

And last but not least, it's not reliable.

2:51.30 – 2:54.46 (3.2s)

It hallucinates and sometimes gives the wrong answer.

2:55.16 – 2:58.46 (3.3s)

The statistics say that 55% of the developers today are actually starting to use Copilot, but only 30% of them are accepting the outcome without any changes.

3:00.50 – 3:12.36 (11.9s)

So if you are a developer and you are not in the first 55%, that means you’re not using AI, and you’re in trouble.

3:12.36 – 3:20.00 (7.6s)

But if you are in the 30%, that means you trust AI too much.

3:20.60 – 3:25.16 (4.6s)

You may be in bigger trouble.

3:25.33 – 3:27.26 (1.9s)

So all the leading AIs today are built on top of large language models, and it’s trained on the text of human knowledge.

3:29.50 – 3:37.36 (7.9s)

It’s impressive.

3:37.70 – 3:38.70 (1.0s)

If you give a clear prompt, it’ll give you very good results.

3:38.70 – 3:42.50 (3.8s)

But all the strategic thinking are still us. It’s the human.

3:42.86 – 3:47.20 (4.3s)

You can think of AI as a brilliant junior developer that you hire to your team, and they can do a lot of jobs very quickly and efficiently.

3:47.46 – 3:57.93 (10.5s)

But it's up to us human to define the vision, to validate the results and ensure what we're building is good for the society.

3:58.26 – 4:08.10 (9.8s)

So there’s another thing that I want to talk about that AI is struggling with.

4:09.76 – 4:14.36 (4.6s)

It's struggling to communicate and collaborate with human beings.

4:14.56 – 4:18.80 (4.2s)

Well, maybe you will say this is more of a human problem, right?

4:19.63 – 4:23.30 (3.7s)

We humans sometimes deal with the same problem too.

4:23.46 – 4:26.26 (2.8s)

But this is something we will have to work out.

4:26.80 – 4:29.56 (2.8s)

Let AI do what AI is good at, and we humans can take care of the boring jobs such as handling office politics.

4:29.56 – 4:37.80 (8.2s)

So talk about the capabilities and limitations of AI.

4:38.63 – 4:42.80 (4.2s)

Now we can take a look at the software engineering roles.

4:43.20 – 4:46.33 (3.1s)

So software engineering roles is not just about writing code.

4:47.66 – 4:52.10 (4.4s)

It actually is about how we need to understand what the user needs.

4:52.10 – 4:57.26 (5.2s)

We need to collaborate across roles and also make tough decisions with empathy and responsibility.

4:57.26 – 5:04.70 (7.4s)

This is what a software engineer should be doing, right?

5:04.90 – 5:07.90 (3.0s)

We're not just text executors.

5:07.90 – 5:09.60 (1.7s)

The best engineers are not the ones who code the fastest, but the ones who think the deepest.

5:10.66 – 5:15.80 (5.1s)

So a good engineer will take messy problems, ambiguous problems, and guide machines towards structured and meaningful outcomes.

5:17.16 – 5:26.26 (9.1s)

So there are system architects who design the best solutions, and they should be the AI collaborators who use AI to implement those solutions.

5:27.00 – 5:38.16 (11.2s)

And then they need to be ethical technologists to make sure the solutions that we’re building are truly benefiting human beings.

5:38.76 – 5:46.96 (8.2s)

So AI is actually democratizing a lot of complicated technical tasks.

5:47.96 – 5:52.93 (5.0s)

Like, today a designer can mock up an application with a prompt.

5:52.96 – 5:59.73 (6.8s)

And also marketers, they don’t need data engineers.

6:00.03 – 6:03.13 (3.1s)

They can just run data analytics without writing any code.

6:03.13 – 6:07.73 (4.6s)

Does that mean software engineers are losing advantages?

6:08.43 – 6:11.73 (3.3s)

The answer is no.

6:12.43 – 6:13.56 (1.1s)

It still remains essential for software engineers.

6:15.63 – 6:18.83 (3.2s)

And the reason is as follows.

6:18.83 – 6:21.20 (2.4s)

First, we understand AI better.

6:22.13 – 6:25.30 (3.2s)

We not only know how to prompt, and we also know what’s under the hood.

6:25.80 – 6:30.10 (4.3s)

The models, the data pipelines, the limitations and risks.

6:30.46 – 6:34.76 (4.3s)

And the understanding of these are very important because AI is integrated into every product we’re using and we’re building in the future.

6:35.50 – 6:44.36 (8.9s)

Second, we can make better use of AI when building software.

6:44.66 – 6:48.80 (4.1s)

So nowadays anybody can prototype a demo or create a simple application of features.

6:49.40 – 6:55.83 (6.4s)

But software engineers think of the bigger picture.

6:56.30 – 6:59.06 (2.8s)

We are actually using AI to build a production-ready software that’s scalable and reliable with long-term maintainability.

6:59.70 – 7:08.46 (8.8s)

Finally, we are making AI better.

7:09.83 – 7:12.56 (2.7s)

We fine-tune models.

7:13.00 – 7:14.53 (1.5s)

We optimize the performance and improve usability.

7:14.53 – 7:18.66 (4.1s)

We make AI available and useful for everybody else.

7:19.10 – 7:22.96 (3.9s)

The next generation of AI is still built by software engineers.

7:23.46 – 7:27.16 (3.7s)

Do you guys remember this quote from CEO of GitHub?

7:27.96 – 7:31.13 (3.2s)

This is not a reality yet.

7:31.66 – 7:33.50 (1.8s)

It's still up to the software engineers to improve AI and make this happen.

7:33.53 – 7:39.70 (6.2s)

So software engineers were not losing the golden ticket to job security.

7:41.53 – 7:46.26 (4.7s)

As a matter of fact, we’re collecting even more because we’re no longer just building software.

7:46.53 – 7:51.16 (4.6s)

We're actually building the future intelligence itself.

7:51.36 – 7:55.06 (3.7s)

And how we train, direct and supervise AI today will define the kind of systems, technology and society that we’re building tomorrow.

7:57.13 – 8:08.43 (11.3s)

AI is raising the floor, but software engineers are raising the ceiling.

8:10.23 – 8:15.06 (4.8s)

And I want to share this not just with… You can applaud, that’s okay.

8:15.86 – 8:19.50 (3.6s)

I want to share this with not just system engineers.

8:19.63 – 8:22.66 (3.0s)

This is for everyone, all right?

8:22.66 – 8:24.30 (1.6s)

We have AI that’s raising us up from the floor.

8:24.33 – 8:26.76 (2.4s)

But it’s us humans that have to reach to the ceiling and raise up the ceiling.

8:26.76 – 8:31.56 (4.8s)

All right, so after all this, now we can talk about software engineering education, right.

8:32.96 – 8:37.73 (4.8s)

So, in the past, coding was a very important piece of software engineering education.

8:37.73 – 8:42.86 (5.1s)

But software engineering education is not just about writing code.

8:42.86 – 8:46.53 (3.7s)

It's also about teaching you how to break complex problems into steps, think logically and critically, and harness the digital tools to build solutions that really matters.

8:46.53 – 8:58.30 (11.8s)

So in a time when AI is everybody’s assistant, engineers become the orchestrators.

8:59.33 – 9:06.66 (7.3s)

We remove barriers and open doors.

9:07.03 – 9:10.30 (3.3s)

And in order for us to be a successful software engineer, the students should go beyond learning code as quickly as possible and get into the following things.

9:11.56 – 9:22.40 (10.8s)

So in order to become a successful engineer in the future, we should focus on mastering the foundations.

9:24.26 – 9:29.90 (5.6s)

The data structure, the algorithm, the programming concepts.

9:30.50 – 9:33.53 (3.0s)

100

They are still very important.

9:33.53 – 9:34.96 (1.4s)

101

Spend enough time to learn all these and become an expert on them because they’re very important basics.

9:34.96 – 9:41.86 (6.9s)

102

Next, think about a system like an architect because, you know, aim higher.

9:42.80 – 9:49.53 (6.7s)

103

Meet the expectation of a senior engineer as soon as possible.

9:49.96 – 9:53.60 (3.6s)

104

And think about designing systems that are reliable and scalable.

9:53.60 – 9:58.03 (4.4s)

105

Go beyond, go full-stack across disciplines.

9:59.83 – 10:03.43 (3.6s)

106

The days when a software engineer could focus on either the front end or the back end or the database are gone.

10:04.00 – 10:11.53 (7.5s)

107

The future software engineers are full-stack engineers.

10:11.86 – 10:14.76 (2.9s)

108

And there’s more.

10:15.13 – 10:16.13 (1.0s)

109

You need to also get into the other disciplines like design, product, data, project management, and be prepared to wear multiple hats.

10:16.23 – 10:23.76 (7.5s)

110

Practice communication and collaborations.

10:25.33 – 10:28.40 (3.1s)

111

Learn to work with people through team projects.

10:28.80 – 10:33.03 (4.2s)

112

Because in the future, if you can explain and connect, it will become increasingly important, and it will set you apart.

10:33.43 – 10:42.83 (9.4s)

113

Use AI as a creative partner.

10:44.56 – 10:46.56 (2.0s)

114

Embrace AI, don’t hate it.

10:47.16 – 10:49.13 (2.0s)

115

And learn LLM, generative AI, model fine-tuning and RAG, etc.

10:49.53 – 10:56.06 (6.5s)

116

You discuss your project with AI, and delegate your work to AI as if it’s one of your teammates.

10:56.76 – 11:02.46 (5.7s)

117

Last but not least, stay adaptable.

11:03.86 – 11:06.33 (2.5s)

118

Tools change, principles last.

11:06.96 – 11:09.80 (2.8s)

119

So you should always focus on learning how to learn.

11:10.46 – 11:13.83 (3.4s)

120

So in the future, when everyone can code a little, the ones who can master the craft, will build the path for everyone and become the leader.

11:15.20 – 11:25.26 (10.1s)

121

So in the era of AI, software engineering is becoming the foundation of leadership.

11:26.00 – 11:32.06 (6.1s)

122

I've talked a lot about programming, but perhaps programmer is no longer the right term we should be using to refer to software engineers.

11:34.60 – 11:41.60 (7.0s)

123

The software engineers of the AI era should be visionaries who can define meaningful problems.

11:42.20 – 11:50.33 (8.1s)

124

A bridge builder who can connect tools, teams and disciplines, and leaders who not only lead human beings, but also lead AI.

11:50.70 – 12:01.00 (10.3s)

125

So the future doesn't belong to those who code the fastest, it should belong to the ones who think deeply, adapt quickly, and collaborate efficiently.

12:01.96 – 12:12.70 (10.7s)

126

They are the ones who don't just predict the future.

12:13.30 – 12:16.16 (2.9s)

127

We build the future.

12:16.66 – 12:17.90 (1.2s)

128

Thank you.

12:19.26 – 12:20.26 (1.0s)

Was ist die Shadowing-Technik?

Shadowing ist eine wissenschaftlich fundierte Sprachlerntechnik, die ursprünglich für die professionelle Dolmetscherausbildung entwickelt und durch den Polyglotten Dr. Alexander Arguelles populär gemacht wurde. Die Methode ist einfach aber wirkungsvoll: Du hörst englisches Audio von Muttersprachlern und wiederholst es sofort laut — wie ein Schatten, der dem Sprecher mit nur 1–2 Sekunden Verzögerung folgt. Anders als passives Hören oder Grammatikübungen zwingt Shadowing dein Gehirn und deine Mundmuskulatur, gleichzeitig echte Sprachmuster zu verarbeiten und zu reproduzieren. Studien zeigen, dass es Aussprachegenauigkeit, Intonation, Rhythmus, verbundene Sprache, Hörverständnis und Sprechflüssigkeit signifikant verbessert — was es zu einer der effektivsten Methoden für die IELTS Speaking-Vorbereitung und reale englische Kommunikation macht.

Wie man auf ShadowingEnglish effektiv übt

Wähle dein Video: Suche ein YouTube-Video mit klarem, natürlichem Englisch. TED Talks, BBC News, Filmszenen, Podcasts oder IELTS-Beispielantworten eignen sich hervorragend. Füge die URL in die Suchleiste ein. Beginne mit kürzeren Videos (unter 5 Minuten) und Inhalten, die dich wirklich interessieren — Motivation ist wichtig.
Zuerst hören, den Kontext verstehen: Beim ersten Durchgang die Geschwindigkeit auf 1x lassen und nur zuhören. Versuche noch nicht zu wiederholen. Konzentriere dich auf das Verstehen der Bedeutung, das Aufnehmen neuer Vokabeln und darauf, wie der Sprecher Wörter betont, Laute verbindet und Pausen nutzt.
Shadowing-Modus einrichten:
- Wartemodus: Wähle +3s oder +5s — nach jedem Satz pausiert das Video automatisch, damit du Zeit hast, ihn laut zu wiederholen. Wähle Manuell, wenn du die volle Kontrolle möchtest und nach jeder Wiederholung selbst auf Weiter drücken willst.
- Untertitel-Sync: YouTube-Untertitel erscheinen manchmal leicht vor oder nach dem Audio. Nutze ±100ms, um sie perfekt auszurichten, damit du genau folgen kannst.
Laut nachsprechen (die Kernübung): Hier passiert die eigentliche Arbeit. Sobald ein Satz gespielt wird — oder während der Pause — wiederhole ihn laut, klar und selbstbewusst. Sprich nicht nur die Wörter nach: Ahme den exakten Rhythmus, die Betonung, Tonhöhe und verbundene Sprache des Sprechers nach. Ziel ist es, wie ein Schatten des Sprechers zu klingen, nicht wie eine Wort-für-Wort-Rezitation. Nutze die Wiederholen-Funktion, um denselben Satz mehrfach zu trainieren, bis er sich natürlich anfühlt.
Die Herausforderung steigern: Wenn sich eine Passage angenehm anfühlt, erhöhe die Herausforderung. Steigere die Geschwindigkeit auf <code>1.25x</code> oder sogar <code>1.5x</code>, um Hochgeschwindigkeits-Sprachreflexe zu trainieren. Oder stelle den Wartemodus auf <code>Aus</code> für kontinuierliches Shadowing — der fortgeschrittenste und lohnendste Modus. Konsequentes tägliches Üben von 15–30 Minuten wird innerhalb von Wochen spürbare Ergebnisse bringen.
