‘AI should be a guiding tool, not a replacement for human thinking’

For Mr Sandeep Sharma, education is as much about values and critical thinking as it is about academic excellence. As Head of Emerging Technologies in Network Services at Tech Mahindra, he works at the forefront of AI-driven telecom advancements, from 5G and satellite communication to 6G’s sensing capabilities. But at home, he is a proud father to Soaham Krishna Sharma (Class 12-B) and Ira Sharma (Class 4-B), both students of Apeejay School, Saket.

In this conversation, Mr Sharma shares his vision for the future of networks, offers guidance on using AI wisely, and reflects on leadership lessons from his career and parenthood.

You lead Emerging Technologies in Network Services at Tech Mahindra. What does that involve in day-to-day work?

Telecom networks today are not just about connectivity; they’re enablers for AI applications, machine learning, and other time-critical services. As we move from 5G towards advanced 5G and 6G, networks must evolve to support these use cases. My role involves ensuring our networks are capable of delivering these emerging services efficiently and securely.

How do you decide which new technologies are worth exploring?

It requires constant research, collaboration with global forums, and analysing trends in
fast-growing industries such as defence, AI/ML, and data consumption. We also assess how automation and optimisation can reduce operational costs across sectors. The goal is to develop network capabilities that benefit both individual consumers and industries.

People are still adapting to 5G. How will 6G be different for everyday users?

While 5G primarily focused on faster data and better voice quality, 6G will be AI-native. This means networks will be designed to run AI-based applications more efficiently. Key innovations will include:

Satellite integration – so your mobile can connect seamlessly, whether you’re in a city, at sea, or mid-flight.

Sensing capabilities – enabling devices to detect surroundings, monitor pollution levels, and support technologies like driverless cars.

These will make coverage ubiquitous and services smarter.

What is your advice on using AI responsibly, especially for students?

AI should be a guiding tool, not a replacement for human thinking. Students must control AI, not the other way around. They should use it to gather ideas but develop their own perspectives. Overreliance can limit creativity and critical thinking. Also, AI models can carry biases and age-inappropriate content, so guardrails are essential.

Many young learners use generative AI tools like ChatGPT. What’s your take on that?

Generative AI can be useful for brainstorming, but students should avoid copy-paste learning. The real value lies in original thought. AI outputs are based on past data and can be biased or incorrect. Industries can detect AI-generated work, so building authentic, novel ideas will always be more rewarding.
