By 2030, we’ll see 170 million jobs created — and 92 million jobs lost.
39% of current skills will be outdated.
And 59% of workers will need reskilling — but 1 in 5 may not get it.

According to the new Future of Jobs 2025 report from the World Economic Forum, AI and information processing tech are expected to transform 86% of businesses — more than any other technology.

We’re not in a “future of work” moment anymore.
We’re in a present of rapid transformation — and AI is at the center of it.

These aren’t just stats.
They’re a snapshot of the pressure — and potential — we’re all navigating.

💡 The AI-native workforce isn’t just technical.
Yes, AI and big data top the list of fastest-growing skills.
But so do:

🔹 Resilience & agility
🔹 Creative thinking
🔹 Curiosity & lifelong learning
🔹 Leadership & influence
🔹 Systems thinking

The world doesn’t just need more AI experts.
It needs more adaptive leaders who can think with AI — strategically, creatively, and ethically.

That’s the mindset we’re helping build in our Executive AI course — for leaders who want to stay ahead of the curve, not chase it.

We dive deep into skills like agentic AI, enterprise data strategy, and predictive decision-making — exactly the capabilities WEF highlights as essential for the future of work.

The brilliant illustration that the ups and downs of life make us progress faster...

> Ups and downs are where to get our momenta, don’t lose our faith when we are at downhills
> Shortest path might not be the fastest

These days many things might be going wrong in different parts of the world but we all need to keep the faith and push forward and make the world a better place!

Interesting concept! Subjects that should be mandatory in schools.

If I could proposal one to include in the schools' subjects, it would be “AI Thinking.“

AI thinking involves understanding the basics of how AI works and being able to differentiate between human abilities and what AI can do; recognizing the strengths and limitations of both humans and AI.

By developing these skills, children would learn how to effectively work alongside AI and make the most of its capabilities. And enable them to comprehend the unique aspects of human capacity and develop them as their core competencies.

Nowadays, we have access to an incredible amount of information, and the way we learn and teach is changing rapidly. The future learning might become customize for each student. What subjects would you like to include in the list?

One min to have a general idea about Neural Network, which is a technique that could achieve many different aims, facial recognition, predicting, music composition, etc.

NN contains virtual ‘neurons’ that are arranged in layers that are connected to each other. The neurons pass on the information and thereby perform calculations.

The connections between the neurons also have values associated with them, called weights.

Those weights tell us how much the information from one layer matters for the next layer. The values of neurons and the weights of the connections are essentially the free parameters of the network.

By training the network, we want to find those values of the parameters that minimize a certain function, called the ‘loss function’. It is an optimization problem, we use a method called backpropagation to solve it.

Backpropagation means if the NN gives us a result that is not good enough, we go back and change the weights of neurons and their connections. This is how the network can learn from failure.

Visualization of global temperature changes from 1880 to 2023, by NASA.

Scientists found that July 2023 was the hottest month on record since 1880, likely due to human activity. 😔

*Data is collected from multiple sources, including satellites, weather stations, and buoys.

I am also curious to see what the data looks like if we can trace it back further in time, and how the patterns change when we extend the timeline to thousands or even millions of years.

When I am into something always curious about how it works!

ChatGPT was trained on massive amounts of data that have been gathered from the internet and other sources through 2021, by using Reinforcement Learning from Human Feedback (RLHF).

It first demonstrates data from humans and trains a supervised policy;
The next step is to run the model and let humans manually rank (label) the quality of outputs produced by the model from best to worst, then collect those new feedback data to train a reward model;
Then use a reinforcement learning algorithm (Proximal Policy Optimization) to optimize a policy by training a model against the reward model. (the key phases of RLHF)

ChatGPT is the third version, it is fine-tuned from a model in the GPT3.5 series (a code model) making it more human-like. Read more in the comments.

#artificialintelligence #generativeai #datascience #chatgpt #technology

OpenAI quietly released a GPT-4.1 Prompting Guide a couple of weeks ago, and it’s one of the most practical resources on how to actually use LLMs well.

Here’s what stood out:

✅ GPT-4.1 is very literal - It follows instructions exactly as written, which is powerful but also unforgiving

✅ Instruction placement matters - Putting them at the start and end of your prompt can improve results

✅ It handles long contexts better, but still benefits from clear structure (delimiters, labels, step-by-step thinking)

✅ Prompt techniques like internal monologue, self-critique, and chain-of-thought can boost reliability

📌 If you’re using ChatGPT, you’re likely using GPT-4 (or now GPT-4o).
📌 But GPT-4.1 is only available through the OpenAI API — and it’s built for more controllable, consistent output in production settings.

Quick takeaway:

If you're writing content, brainstorming, or doing 𝗴𝗲𝗻𝗲𝗿𝗮𝗹 𝘄𝗼𝗿𝗸 → ChatGPT with GPT-4o is great

If you're 𝗯𝘂𝗶𝗹𝗱𝗶𝗻𝗴 𝘁𝗼𝗼𝗹𝘀, 𝗮𝗽𝗽𝘀, or need 𝗰𝗼𝗻𝘁𝗿𝗼𝗹 over the full prompt/response pipeline → GPT-4.1 via API is a better fit

Monthly Book Review: Two books for building with GenAI (Foundations + Applications)

Took me five months to get to my second book review, but hopefully still counts as a series, right? 😂

This time, I’m sharing two books together - 
focus on different stages, make a good match to cover a lot of ground for anyone building real-world GenAI applications.

Highly recommend especially if you're working on any serious LLM projects this year. Let's start!

📘 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐀𝐈 𝐰𝐢𝐭𝐡 𝐏𝐲𝐭𝐡𝐨𝐧 𝐚𝐧𝐝 𝐏𝐲𝐓𝐨𝐫𝐜𝐡 (𝟐𝐧𝐝 𝐄𝐝𝐢𝐭𝐢𝐨𝐧) - recommend to start with this one first

In short, this book is about understanding how modern GenAI models work and building them from scratch - great if you want to dive deep, and not just how to prompt.

It starts with the foundations: transformers, embeddings, training LLMs; and then moves into more advanced topics like fine-tuning models, building diffusion models (for image generation), and has a touch on the latest trends like multimodal AI.

What I personally liked the most:

- It's technical, but very approachable if you have some Python background.

- A strong focus on building from scratch, you don't just run libraries, you understand what's happening under the hood.

- It doesn’t overwhelm you with theory either; every concept is quickly tied to something you can actually build.

But if you’re newer to PyTorch or deep learning, you might want to brush up a little before jumping in. But overall, it’s a smooth and rewarding read, especially if you're hands-on.

📙 𝐆𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐀𝐈 𝐰𝐢𝐭𝐡 𝐋𝐚𝐧𝐠𝐂𝐡𝐚𝐢𝐧

In short, you will learn how to orchestrate and deploy modern GenAI models into robust real-world applications.

This book focuses on the real-world application side, how to actually build and deploy LLM-powered systems.

It walks through using LangChain and LangGraph to create structured pipelines, smart agents, and robust applications that can handle real-world complexity (not just simple question answering).

What stood out for me the most:

- It’s packed with practical patterns: memory handling, tool usage, agent frameworks, evaluations; things that show up all the time when you move beyond demos.

- The LangGraph part is a big highlight. 
It shows a clear, modular way to design more reliable flows, for who ever struggled with keeping agent systems organized as they scale.

- Very deployment-minded. 
Less “how to build a cool project” 
More “how to ship something that actually works reliably in production”

A bit of Python and LLM background helps, but overall, it’s a very practitioner-focused guide, not academic, not too theoretical.

✔️ Generative AI with LangChain: https://packt.link/59uUr

I am a big fan of a quick start and small steps when I try to learn a new skill from absolutely zero, even if the final goal is very far away.

The shorter sub-goals return a more frequent sense of achievement, which helps me to build confidence and motivates me to go further in a new area. When I feel difficult to go through it, I will reconsider the length and material, rather than be self-blaming and deeply guilty.

AI is not limited to LLMs. There’s a high chance most of us already use AI more than we realize.

Imagine a day like this, and see how many activities you knew you were interacting with AI:

1) Your morning starts with checking your spam folder for an email you've been waiting for - 𝐞𝐦𝐚𝐢𝐥 𝐬𝐩𝐚𝐦 𝐟𝐢𝐥𝐭𝐞𝐫.

2) During lunch break, you book tickets for your next vacation and chat with a customer support bot when you encounter a payment error - 𝐜𝐡𝐚𝐭𝐛𝐨𝐭.

3) At 6 PM, back home, you do some exercise with your smartwatch and put on a suggested playlist - 𝐟𝐢𝐭𝐧𝐞𝐬𝐬 𝐭𝐫𝐚𝐜𝐤𝐞𝐫/ 𝐩𝐥𝐚𝐲𝐥𝐢𝐬𝐭 𝐫𝐞𝐜𝐨𝐦𝐦𝐞𝐧𝐝𝐚𝐭𝐢𝐨𝐧.

4) Your neighbor comes by and rings your camera doorbell - 𝐬𝐦𝐚𝐫𝐭 𝐬𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐜𝐚𝐦𝐞𝐫𝐚.

5) Open Uber Eats to order food delivery - 𝐨𝐩𝐭𝐢𝐦𝐢𝐳𝐞 𝐫𝐨𝐮𝐭𝐞𝐬 𝐚𝐧𝐝 𝐞𝐬𝐭𝐢𝐦𝐚𝐭𝐞 𝐚𝐫𝐫𝐢𝐯𝐚𝐥 𝐭𝐢𝐦𝐞𝐬.

6) Later, with your kids, you browse recommended shows on Netflix - 𝐩𝐫𝐨𝐝𝐮𝐜𝐭 𝐫𝐞𝐜𝐨𝐦𝐦𝐞𝐧𝐝𝐚𝐭𝐢𝐨𝐧𝐬.

*Bonus: Live webinar on 'Build a Recommendation System', practical and free to join (starts in 12 hours)
https://bit.ly/4fP7tgu

7) Before sleep, you open Facebook and see you've been tagged in photos your friends shared – 𝐢𝐦𝐚𝐠𝐞 𝐫𝐞𝐜𝐨𝐠𝐧𝐢𝐭𝐢𝐨𝐧.

Those are all applications of AI. How many did you recognize?

Not every single application seems exciting, right? Actually, about 90% of AI solutions for real-world projects are still based ML algorithms, not LLMs or other super-advanced algorithms.

Another reason might be that many things have been incorporated into AI over time, but most of them operate in the background.

This trend has been ongoing for over a decade and has literally been integrated into every aspect of our lives.

This includes decision-making processes, such as which political ads we see, what jobs we qualify for, whether we qualify for loans, etc.

I enjoy the benefits of technology, but I also like to keep myself mindful of its influence and how it may shape my decisions and experiences.

What Are Agentic Design Patterns?

We talked about AI Agents as 'doers' (autonomous actors that plan, take action, and adapt)

Agentic AI is the broader concept, where system behaving autonomously and goal-oriented.

Often using multiple agents working in coordination through agentic workflows.

To build these systems, developers use design patterns, which are reusable architectural templates.

The field is evolving fast. Besides the 6 common patterns (shown in the image), some other notable pattens worth checking too,

especially for more advanced or or domain-specific systems (e.g. enterprise AI, robotics, R&D environments).

◾ 𝗠𝗲𝗺𝗼𝗿𝘆-𝗔𝘂𝗴𝗺𝗲𝗻𝘁𝗲𝗱 𝗔𝗴𝗲𝗻𝘁𝘀
Adds short-term or long-term memory to agents.

**Enables personalization, context carryover, and better reasoning over time.

Used in: LangChain Memory, ChatGPT custom GPTs with memory

Good for: Agents that need continuity (e.g. CRM agents, tutoring bots)

◾𝗘𝘃𝗲𝗻𝘁-𝗗𝗿𝗶𝘃𝗲𝗻 𝗔𝗴𝗲𝗻𝘁𝘀
Agents triggered by system events, data updates, or user actions (not just prompts)

**Enables automation and real-time responsiveness.

Used in: Zapier AI, Slackbots, enterprise automation tools

Good for: Internal ops, alerts, or workflows like
“If new order → summarize → send to Notion”

◾𝗘𝗻𝘀𝗲𝗺𝗯𝗹𝗲 / 𝗩𝗼𝘁𝗶𝗻𝗴 𝗔𝗴𝗲𝗻𝘁𝘀
Multiple agents (or models) generate options, and a “judge” selects the best one.

**Improves quality, reduces hallucination, balances multiple perspectives.

Used in: OpenAI’s system message testing, research LLM evaluations, SuperAGI

Good for: Content generation, code generation, or safety-sensitive domains

◾𝗦𝗶𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻-𝗕𝗮𝘀𝗲𝗱 𝗔𝗴𝗲𝗻𝘁𝘀
Agents that operate and learn inside simulated environments.

**Safe space for testing strategies, training, and multi-agent collaboration.

Used in: Meta’s CICERO (Diplomacy), Voyager in Minecraft, MARL research

Good for: Robotics, gaming, R&D, or long-term planning

💡Patterns aren’t mutually exclusive, acutally the most advanced agentic systems combine several of them to get smarter, faster, and more reliable over time.

Personally, I’ve seen memory-augmented and multi-agent patterns the most, especially when trying to scale workflows or personalize outputs over time.

Curious, which ones have you used or seen most often in action? Any interesting examples out in the wild?

50X faster data analysis with NVIDIA's open-source accelerator!

Pandas accelerator from Nvidia's RAPIDS cuDF, a GPU-accelerated library for data manipulation and analysis, similar to the popular Pandas library in Python.

It's interesting to see how Nvidia made it easy to use - they introduced a way to deploy cuDF with just a module flag when running the script or through an extension load in a notebook.

This allows you to easily switch to using cuDF instead of Pandas, without having to change your code.

pip install cudf
conda install cudf -c nvidia

Make sure you have:
- Python 3.9 or later
- NVIDIA GPU with CUDA support
- CUDA installed (version 11.2 or later)
- cuDF is installed on the same environment as your Python installation

Have fun!😎

AI is not limited to LLMs. Most likely many of us already use AI daily more than we realize.

Imagine a day like this, and see how many activities you knew you were interacting with AI:

1) Start your morning by checking the spam folder for an email you’ve been waiting for - 𝐞𝐦𝐚𝐢𝐥 𝐬𝐩𝐚𝐦 𝐟𝐢𝐥𝐭𝐞𝐫.

2) During lunch break, you book tickets for your next vacation and chat with a customer support bot when you encounter a payment error - 𝐜𝐡𝐚𝐭𝐛𝐨𝐭.

3) At 6 PM, head home, exercise with your smartwatch, and put on a playlist it recommends - 𝐟𝐢𝐭𝐧𝐞𝐬𝐬 𝐭𝐫𝐚𝐜𝐤𝐞𝐫/ 𝐩𝐥𝐚𝐲𝐥𝐢𝐬𝐭 𝐫𝐞𝐜𝐨𝐦𝐦𝐞𝐧𝐝𝐚𝐭𝐢𝐨𝐧.

4) Open Uber Eats to order food delivery - 𝐨𝐩𝐭𝐢𝐦𝐢𝐳𝐞 𝐫𝐨𝐮𝐭𝐞𝐬 𝐚𝐧𝐝 𝐞𝐬𝐭𝐢𝐦𝐚𝐭𝐞 𝐚𝐫𝐫𝐢𝐯𝐚𝐥 𝐭𝐢𝐦𝐞𝐬.

5) Your neighbor comes by and rings your camera doorbell - 𝐬𝐦𝐚𝐫𝐭 𝐬𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐜𝐚𝐦𝐞𝐫𝐚.

6) Later, with your kids, you browse recommended shows on Netflix - 𝐩𝐫𝐨𝐝𝐮𝐜𝐭 𝐫𝐞𝐜𝐨𝐦𝐦𝐞𝐧𝐝𝐚𝐭𝐢𝐨𝐧𝐬.

7) Before sleep, you open Facebook and see you've been tagged in photos your friends shared – 𝐢𝐦𝐚𝐠𝐞 𝐫𝐞𝐜𝐨𝐠𝐧𝐢𝐭𝐢𝐨𝐧.

Those are all applications of AI. How many did you recognize?

Also, an update from Google certificates, they just updated some of their foundational programs with real-world AI applications, if you’re eyeing on those courses, time to check:

✔️UX Design https://lnkd.in/gtdb_fWc
✔️Digital Marketing & E-commerce https://lnkd.in/gndBvPqy
✔️Cybersecurity https://lnkd.in/gZM6fUva
✔️Project Management https://lnkd.in/gg58JsP2

*I use Coursera, but you can also find those courses on other platforms.

🔉Breaking: The DeepSeek Conspiracy

The House of OpenAI, once the uncontested ruler of the realm, now finds itself in turmoil. A new challenger has risen from the East—DeepSeek, the rogue alchemist who, with cunning and coin, has forged a model that rivals the might of the great O1… and gave it to the people for free.

But the gods of Silicon Valley do not forgive so easily. Whispers in the keep of Microsoft’s Azure Towers speak of stolen magic—𝗢𝗽𝗲𝗻𝗔𝗜 𝗻𝗼𝘄 𝗮𝗰𝗰𝘂𝘀𝗲𝘀 𝗗𝗲𝗲𝗽𝗦𝗲𝗲𝗸 𝗼𝗳 𝗱𝗶𝘀𝘁𝗶𝗹𝗹𝗶𝗻𝗴 𝘁𝗵𝗲𝗶𝗿 𝘃𝗲𝗿𝘆 𝗲𝘀𝘀𝗲𝗻𝗰𝗲, siphoning the knowledge from their sacred models like a shadowy apprentice learning forbidden spells.

The accusation? 𝗗𝗶𝘀𝘁𝗶𝗹𝗹𝗮𝘁𝗶𝗼𝗻, a dark art where one takes the wisdom of a mighty, well-trained AI and transfers it into a smaller, more efficient model. A clever trick, yet one that OpenAI deems high treason, for it was done not with scrolls and study, but through the plundering of API calls.

Microsoft’s ravens claim to have seen 𝘃𝗮𝘀𝘁 𝗱𝗮𝘁𝗮 𝘀𝗺𝘂𝗴𝗴𝗹𝗲𝗱 into the East, and the lords of the Valley demand justice.

But the story does not end there. Even as OpenAI sharpens its blades, House Alibaba has unleashed 𝗤𝘂𝗲𝗻 𝟮.𝟱 𝗠𝗮𝘅, another open-source warrior, standing alongside Kim 1.5, yet another rising power.

And in the shadows, the architects of DeepSeek have 𝗯𝘆𝗽𝗮𝘀𝘀𝗲𝗱 𝗖𝗨𝗗𝗔 𝗶𝘁𝘀𝗲𝗹𝗳, forsaking Nvidia’s dominion to carve their own path with sheer technical mastery.

If the rumors are true, this band of rogue engineers has achieved 10x the efficiency of their rivals—something that should not be possible by the laws of the land.

Yet, as this war rages, there is a deeper irony. The great houses have all played the game of shadows before.

Did OpenAI not once 𝘀𝗰𝗼𝘂𝗿 𝘁𝗵𝗲 𝗹𝗮𝗻𝗱𝘀 𝗼𝗳 𝘁𝗵𝗲 𝗶𝗻𝘁𝗲𝗿𝗻𝗲𝘁, feasting on the texts of bards and scholars alike? Did they not once laugh in the face of copyright lords, only to now cry foul when another dares the same?

The drama unfolds, and the question remains: Is DeepSeek the Robin Hood of AI, stealing from the rich to gift intelligence to the world? Or are they mere opportunists, cloaked in the garb of revolutionaries?

One thing is certain—the war for AI dominance has only begun. And in this game, as in all others, you either innovate… or you become obsolete.

Traditionally, data scientists use AI models for analysis, and are great data storytellers at a high level.

AI engineers, more specifically generative AI engineers, are like AI system builders. They use foundation models to build generative AI systems that transform business processes.

*EDA: exploratory data analysis

*Scope: refers to the scope of tasks that can be solved by an individual model

*The image highlights the major differences, but it's not absolute. Data scientists also work on prescriptive use cases, and AI engineers work with structured data.
