The world of work is undergoing a massive transformation due to Artificial Intelligence (AI), which is a very new and rapidly changing field. It’s predicted that AI will replace many jobs, making it absolutely essential for individuals – from those finishing school to graduates and industry professionals – to learn AI to stay relevant in their careers and secure better salary packages. The job market already reflects this shift, with AI jobs in India soaring by 38%, significantly outperforming traditional tech roles. Between April and June 2025 alone, over 35,000 AI and Machine Learning (ML) jobs were posted on Naukri.com, a testament to AI’s incredibly fast growth. While non-AI tech jobs grew by only 8%, AI roles saw a 38% jump from the previous year, highlighting how quickly the industry is shifting.

Integrating AI into daily tasks is becoming commonplace; for instance, the presenter personally uses AI for content creation, voice generation, video creation, data generation, fact-finding, and even generating questions. Beyond individual relevance, AI offers substantial economic benefits: a PwC study revealed a 3x higher growth in revenue per worker in industries more exposed to AI. Moreover, workers with AI skills enjoy a significant 56% wage premium compared to those in the same job without AI expertise, a substantial increase from 25% last year. For AI professionals in India, the median salaries are impressive: AI Engineers earn around ₹91.8 lakh, AI Consultants are close to ₹98 lakh (nearly ₹1 crore), and AI Researchers command similar figures at ₹97-98 lakh. While these high salaries are part of a current market boom and may normalise in 5-7 years, the opportunity to capitalise on this is now.

India is facing an impending AI talent crunch, with a demand for 1 million more skilled AI workers by 2027. Colleges simply cannot adapt their curricula fast enough to meet this demand, meaning a massive need for upskilling and self-learning AI exists. To bridge this gap, seven essential free AI courses are recommended:

1. Basic Mathematics:

This is the fundamental prerequisite for understanding AI and ML, not just using it. Google and AI developers themselves stress its importance. Key topics include Algebra, Linear Algebra, Trigonometry, Statistics, and Calculus. A free “Math for Machine Learning” course is available on GeeksforGeeks. The immense value of mathematics is underscored by the case of Traphit Bansal, a PhD researcher in Mathematics, who was reportedly hired by Meta from OpenAI for a staggering ₹800 crore (USD 100 million).

2. Python:

An easy-to-learn, beginner-friendly coding language crucial for effectively using AI tools. It enables fast experimentation. Learners should cover basic syntax, concepts, control structures, functions, data structures, and work with libraries like Pandas, NumPy, Matplotlib, TensorFlow, PyTorch, and Scikit-learn. IBM offers a free “Python for Data Science and AI Developers” course on Coursera, taught by Joseph Saracangelo.

3. AI for Everyone:

Taught by Andrew Ng, co-founder of Coursera, this beginner-level course on Coursera helps you understand what AI can and cannot do, how to use it without coding, its real-life applications, and crucial ethical considerations. It takes approximately 6 hours.

4. ChatGPT Prompt Engineering Essentials:

This highly important course, available on DeepLearning.AI, teaches the art of writing smart, clear instructions (prompts) to get better, more useful responses from AI tools like ChatGPT. It helps unlock AI’s full power and work with any AI tool. The course, lasting 1.5 hours, is taught by Isa Fulford and Andrew Ng, and requires a basic understanding of Python.

5. Vibe Coding 1 with Replit:

Offered on DeepLearning.AI, this 1.5-hour beginner course focuses on making coding fun and creative within a browser-based environment. Taught by Michelle Catasta and Matt Palmer, it teaches core programming concepts and encourages building projects like mini-games or chatbots. No prior technical experience is needed.

6. Building Systems with the ChatGPT API:

Provided by OpenAI on DeepLearning.AI, this course, lasting about 1.75 hours, teaches how to create your own apps, tools, or automations that leverage ChatGPT’s power via its API. It requires a basic understanding of Python and is taught by Isa Fulford and Andrew Ng.

7. Machine Learning Specialization:

An advanced-level course on Coursera, co-created by DeepLearning.AI and Stanford University, and taught by Andrew Ng, Geoff Ludwik, and Aarti Bagul. It helps build a strong foundation in core AI and ML concepts, enabling you to build real projects. This is a longer commitment, about 2 months (approx. 80 hours total), and requires basic coding (for loops, functions, if/else statements) and high-school level maths (arithmetic, algebra).

In a world transformed by AI, staying still means falling behind — but with the right knowledge, anyone can move forward. Learning is no longer optional; it is the currency of survival and success.
