As AI surges ahead and concerns grow about machines becoming conscious, the mystery of consciousness has jumped from dusty philosophy books into everyday conversations. Once the private playground of philosophers and mystics, it has now become the greatest unsolved puzzle in science — and perhaps the key to understanding both ourselves and the machines we create.
Consciousness is ever-present, at least during our waking time. It is what accompanies all our subjective experiences – the redness of the sun we experience during a sunset or the unpleasant sound of honking at a traffic signal. Yet, we have absolutely no idea how it works.
The real problem isn't just finding an explanation of how consciousness happens. We don't even know what a good explanation would look like. Australian philosopher David Chalmers captured this perfectly by calling it the 'hard problem of consciousness.'
To understand the 'hard problem,' it's important to grasp the 'easy problems.' Neuroscientists map neural correlates of consciousness (NCC) — brain activities linked to specific experiences. For instance, a toothache activates certain neural circuits in the brain. Despite its name, the 'easy problem' isn't easy, but substantial progress has been made in mapping NCCs in the recent decades.
Back in 1998, renowned neuroscientist Christof Koch and Chalmers made a friendly bet. Koch believed scientists would uncover a specific NCC within 25 years. Chalmers wagered against it. In 2023, Koch conceded defeat, gifting Chalmers a case of fine wine. Koch remarked, 'In twenty-five years, we have mapped the brain, but the mystery of consciousness remains unsolved.'
The 'hard problem' asks — why do brain processes result in subjective experiences like blueness of sky or the joy of watching a sunrise? Knowing which neurons fire when we taste chocolate is one thing, explaining why it tastes delightful is another. A deep 'understanding gap' remains between physical processes and subjective experience.
Modern science approaches this bottom-up, assuming matter is fundamental and consciousness emerges from it. But thinkers like Philip Goff and B. Alan Wallace challenge this view. They argue consciousness is primary — all knowledge of matter comes through conscious experience. Explaining consciousness through matter might just be circular logic. Roger Penrose, a Nobel Lareate in physics said 'I argue that the phenomenon of consciousness cannot be accommodated within the framework of present-day physical theory.'
So, if studying matter won't reveal consciousness, is understanding it even possible? Thankfully, ancient Indian and Tibetan traditions developed rigorous methods for studying consciousness by turning their attention inward. Over centuries, rich schools of thought have emerged. Two beautiful traditions stand out: Advaita Vedanta and Dzogchen Buddhism.
Advaita Vedanta: Dreaming while awake
Advaita Vedanta teaches that there is only one true reality – pure consciousness, called Brahman. The world around us is like a dream, known as Maya. The individual self, or Atman, is also pure consciousness. According to Advaita, mind or consciousness is the only true reality — a monistic view, unlike dualism, which sees both mind and matter as real.
Modern science is also monistic, but it claims only matter is real. It sees mind as emerging when matter becomes complex, like the brain producing thoughts. Advaita flips this idea, mind comes first, and matter is a projection of mind like dreaming of mountains and rivers. They seem real, but when you wake up, you realize they were just mind-creations.
Imagine dreaming you are standing on a high cliff, heart racing with fear. Upon waking, you realize there was no cliff, only your mind. Similarly, Advaita says the world seems real only until we recognize deeper truth.
Dzogchen Buddhism: Recognizing the Open Sky
The Dzogchen tradition of Tibetan Buddhism offers a similar but powerful approach. Its goal is recognizing Rigpa — a pristine, sky-like awareness beyond thoughts and perceptions. It is a state where the distinction between subject and object dissolves into oneness. Like Advaita, it is rooted in non-dualism.
Practice of Trekchö ('cutting through rigidity') helps practitioners see mental events as fleeting and transparent. It is considered one of the quickest ways to glimpse non-duality as it aims to cutting through the mental conceptions quickly and recognizing Rigpa. Practices like Samatha (calm abiding) and Vipassana (insight meditation) can help prepare the mind for this direct recognition but they are not necessary.
Thus consciousness can be understood by recognising it through direct experience compared to some intellectual theorization. A scene from The Matrix captures this spirit perfectly. When Neo asks how he will know he is 'The One,' the Oracle tells him, 'Being The One is just like being in love — you just know it.' Renowned consciousness researcher Giulio Tononi echoes the sentiment by saying, 'Consciousness becomes a matter of 'being' rather than 'doing'.'
As machines mimic more and more of our behaviour, the risk is not just that we build conscious robots but that we forget what it truly means to be conscious ourselves. In a world rushing forward on the wheels of AI, perhaps the ancient quest to understand consciousness is not a relic of the past but a survival guide for the future. To know consciousness, not just study it, but live it, may turn out to be our greatest act of wisdom.

Indian firms target overseas assets to fast-track semiconductor ambitions
Strategic overseas acquisitions by India's nascent semiconductor companies are set to emerge as a key enabler for the country's ambitions in chip manufacturing and assembly, ensuring access to proprietary expertise, precision equipment, and critical intellectual property, experts told ET. Indian firms including Tata Electronics and L&T Semiconductor Technologies (LTSCT) have recently made significant moves to acquire foreign assets even as they invest in greenfield facilities within the country. These acquisitions bring experienced engineering teams and operational know-how, which are essential for upskilling local workforces and establishing robust training pipelines, explained Kunal Chaudhary, partner and co-leader, inbound investment group, at EY India. LTSCT and Kaynes Semicon are jointly acquiring the power modules business of Fujitsu General Electronics, based in Japan, while opto-semiconductor maker Polymatech last year acquired US-based semiconductor equipment provider Nisene Technology Group to build an integrated chip manufacturing business. Tata Electronics is exploring takeovers of semiconductor fabrication and outsourced semiconductor assembly and test (OSAT) facilities in Malaysia. Chaudhary said while India has already built a strong presence in chip design, moving into OSAT — a high-margin segment that includes advanced packaging and assembly — will be key to climbing the value chain. Discover the stories of your interest Blockchain 5 Stories Cyber-safety 7 Stories Fintech 9 Stories E-comm 9 Stories ML 8 Stories Edtech 6 Stories With advanced packaging technologies becoming critical to semiconductor innovation, India's entry into this space could enhance its global positioning, he said. After Kaynes and LTSCT announced acquisition of Fujitsu General's power modules business for Rs 118.34 crore on Monday, Kaynes CEO Raghu Panicker said the deal opens up new avenues for advanced semiconductor packaging excellence. 'This move strengthens Kaynes' OSAT capabilities, while aligning with our long-term strategy of supporting global original equipment manufacturers through best-in-class technology and scalable infrastructure,' he told ET. Kaynes is one of the four companies under the India Semiconductor Mission 1.0 building OSATs in the country, while Larsen & Toubro has invested more than $300 million to create its fabless chip company LTSCT. ET on June 3 reported that Tata Electronics is in talks with several global semiconductor companies to acquire a fabrication or OSAT plant in Malaysia. The move is aimed at bolstering the Tata Group company's knowledge and talent base ahead of its ambitious foray into semiconductor fab, assembly and packaging in India. 'Most acquisitions and partnerships at the moment are really about two things: gaining access to trained talent – essentially acqui-hires – and jump-starting work on cutting-edge technologies,' said Prithvideep Singh, general manager at Mohali-based Continental Device India Ltd (CDIL) that has a partnership with German semiconductor manufacturer Infineon Technologies. 'Gaining access to know-how is only half the battle,' he said. 'Transferring it to Indian operations and building capability within local teams…demand years of groundwork, deep technical maturity, and process discipline.' Infineon supplies high performance silicon wafers, and CDIL packages and distributes advanced power semiconductors like MOSFETs and modules specifically tailored for the Indian market, including for electric vehicles and renewables. 'All the JVs and strategic partnerships are a result of the need for Indian entities to build their core competency with best in class proven technology and manufacturing processes,' said Neil Shah, cofounder and vice-president, research, at Counterpoint Research. He noted that matured nodes foundry and back-end packaging OSAT/ATMP are low hanging opportunities for new entrants. 'Building fabs for advanced nodes is still a distant dream for Indian enterprises as there are just three big players like TSMC, the leader, and Samsung and Intel, which are still struggling versus TSMC,' Shah said. 'So, high value fab will take time if at all one of them decides to set up in India in future, if the other ecosystems develop handsomely,' he explained. Biswajeet Mahapatra, principal analyst at Forrester, said acquiring assets of foreign entities allows Indian companies to access advanced technologies like wafer-level packaging, 2.5D/3D integration, and chiplet-based designs, which are critical for modern semiconductors. By leveraging foreign expertise and infrastructure, Indian companies can reduce reliance on imports for high-end packaging solutions and meet the growing demand from global OEMs like Apple and Intel, he explained. For the broader ecosystem, overseas acquisitions and partnerships can help bridge critical capability gaps. Given the current talent crunch in India, they offer a smart and often necessary path for companies entering the sector, experts said. But the real challenge lies in how effectively that know-how is embedded into Indian operations and scaled with consistency and quality, they added.

US on-site openings shrink for techies as IT hits pause button
Live Events Several Indian software services majors have hit the pause button on on-site deputations of their skilled workers to client locations in the US, preferring to "wait & see" amid continued business uncertainties and tighter immigration policies in the US, multiple people told companies such as Tata Consultancy Services (TCS), Infosys and Wipro have cleared hundreds of their workers to take up foreign assignments as far back as 24 months but are going slow on letting them apply for the visa stamping process and plan their travel."Our company is allowing US travel to client locations only in emergency cases. Regular deputations have been put on hold," a senior professional with Bengaluru-headquartered Infosys told ET, declining to be identified."The brakes have been applied despite clearing my entire documentation process in 2023 itself. Clients have also given the green signal, but there is no headway," another employee said, adding those picked up by the lottery system in 2024 are stuck at the documentation a rival tech major, about 600 employees selected in 2023-24 are on a wait list. The company abandoned the nomination process last year but has resumed it this year. The company has told those on the waitlist not to worry as their visa would be valid for three years and they would be sent US has a long waitlist for applications from India . They will get cleared once more clarity emerges from the US government, said a tech lead at companies did not respond to emailed requests for employee from Wipro said this is influenced more by the business dynamics than the regime changes in the US "which also may have played a small part. They may be waiting for some clarity to emerge on how prepared clients are to sustain or increase the budgets on compensating overseas workers on short-duration work visits."For technology services, hiring locals or even subcontractors at client locations, which are typically external specialists or consultants, usually spikes the employee expenses due to higher benchmark salaries overseas. Therefore, most Indian IT firms depute employees from offshore delivery locations such as India on projects for a temporary period to save demand has been slowing from clients and AI-led efficiencies are also reducing the need for such deputations. Besides, tighter visa regulations in the US for immigrants as well as push for employment of locals is leading companies to pause such decisions, analysts say.
