19 April 2025: Sixty Years of Moore’s Law: A Prophetic Vision Still Shaping the Digital Future

On April
19, 1965, a relatively unassuming article published in Electronics magazine by
Gordon E. Moore, then Director of R&D at Fairchild Semiconductor and later
co-founder of Intel Corporation, would go on to transform the digital world.
Titled “Cramming more components onto integrated circuits”, the article
predicted that the number of transistors on a silicon chip would double
approximately every year, leading to exponential growth in computing
capabilities and a decline in cost per function. This idea — later dubbed
Moore’s Law — has become one of the most influential forecasts in the history
of semiconductor technology.
The 1956 Nobel prize winning works in Physics of William Shockley, John Bardeen and Walter Brattain at the Bell Labs "for their researches on semiconductors and their discovery of the transistor effect" led to the path breaking development of the wonder device, the transistor, a device that revolutionized electronics leading to the semiconductor industry. The Silicon Valley, Internet and the World Wide Web were technological triumphs of the late 20th Century. When this common architecture for digital information and communications became wedded to the broadband fixed and mobile networks, it brought together previously distinct communications markets for data, voice and broadcast content. This marriage allowed society to take full advantage of the technological benefits of new generation of computer architectures enabled by a very large array of cheap data storage and processors, which ushered us in to this modern world that is driven by path breaking technologies like the Artificial Intelligence, Virtual Reality, 3D Printing and such other technologies that collectively are dubbed the IR4.0. Today as we celebrate the six decades of the prophetic vision of Gordon Moore, an attempt is made here to see how his vision has shaped the IT industry and its future.
Incidentally, I had published an article in Dream 2047, October 2006 issue, under the title “Gordon Moore, His Law and Integrated Circuits”, the link of the monthly magazine published by Vigyan Prasar, an autonomous organisation of the Department of Science and Technology, Government of India, is given below and my article can be found on page 35.

From Insight to Industry Doctrine
Moore’s prediction, based on just a handful of years of data from the nascent semiconductor industry, proved admirably accurate. Though he later revised the time frame to a doubling every two years, the essence of his vision — exponential progress through miniaturization — remained relevant. What’s more extraordinary is how this simple observation became a self-fulfilling prophecy, driving the semiconductor industry to adopt technology roadmaps and innovation cycles aligned with the pace Moore envisioned sixty years ago.
Moore’s Law catalysed decades of innovation. It enabled the proliferation of personal computers, smartphones, automated vehicles, and now, artificial intelligence. His forecast was made just four years after the development of the first planar integrated circuit by Robert Noyce, with whom Moore would go on to found Intel in 1968.
The Physics of Progress: Silicon and Beyond
Silicon, the backbone of modern electronics, is one of Earth’s most abundant elements, found widely in sand. It offered cost-effective scalability, and in the early decades, it was possible to follow Moore’s Law simply by shrinking transistor sizes. This led to the evolution from small-scale integration (SSI) to large-scale (LSI), very large-scale (VLSI), and eventually ultra-large-scale integration (ULSI) — packing billions of transistors into chips as small as fingernails.
Yet, as transistor dimensions approach the atomic scale (currently ~2 nanometres in leading-edge commercial chips), continuing this trend faces formidable challenges — quantum tunnelling, heat dissipation, and lithographic limitations. This has led to an industry-wide recognition that Moore’s Law is no longer a guarantee, but a goalpost that demands entirely new paradigms.
Rethinking Moore: Innovations That Keep the Vision Alive
The semiconductor industry is actively working to extend Moore’s Law, despite facing physical limits. Traditional scaling, where transistors shrink to nanometre scales, is becoming challenging due to silicon constraints and heat dissipation issues. However, research suggests solutions like advanced packaging (e.g., Intel’s RibbonFET and PowerVia with Intel 20A and 18A processes) and new materials (e.g., graphene, carbon nanotubes) are being explored. Intel aims for a trillion transistors on a package by 2030 (Intel’s Commitment to Moore’s Law), and the industry is adopting "More than Moore" strategies, integrating non-silicon technologies for enhanced functionality.
The semiconductor industry is trying to constantly push the boundaries by diversifying its approaches, which include, among others;
1. Advanced Node Fabrication: Companies like TSMC, Intel, and Samsung are pushing sub-3nm nodes using EUV lithography and novel Gate-All-Around FETs to improve performance and energy efficiency.
2. Chiplet and 3D Integration: Instead of making one massive chip, companies are designing modular chiplets connected via high-speed interconnects, allowing scaling without shrinking.
3. Materials Innovation: Beyond silicon, compound semiconductors (e.g., GaN, SiC), 2D materials like graphene and transition metal dichalcogenides (TMDs), are being explored to create faster and more efficient transistors.
4. Photonic and Neuromorphic Computing: Integrating light-based data transmission and brain-inspired computing architectures is yielding advances in speed and efficiency.
Quantum Computing: The Next Paradigm Shift
As we commemorate 60 years of Moore’s Law today, the world also celebrates the International Year of Quantum Science and Technology (2025). The timing is symbolic — we stand at a potential inflection point where quantum computing may redefine what “scaling” means.
Quantum computing doesn’t follow Moore’s Law per se, but it opens an entirely new dimension of parallelism and problem-solving. With qubits instead of bits, and superposition instead of binary logic, quantum systems can address complex problems in materials science, cryptography, and AI that are practically impossible for classical computers.
Companies like IBM, Google, and start-ups like Rigetti and IonQ are aggressively pursuing quantum processors with growing qubit counts and decreasing error rates. Meanwhile, quantum-classical hybrid systems are emerging as a bridge between current hardware and quantum futures.
India’s Semiconductor Aspirations and Global Momentum
India, too, is actively investing in the semiconductor ecosystem, with initiatives like the Semicon India Programme, the establishment of fab proposals, and research in quantum materials and spintronics. The global race to localize chip manufacturing and develop quantum capabilities is reshaping geopolitics and economic priorities.
A Legacy That Lives On
In 2006, as mentioned above, I had an opportunity to publish an article reflecting on Moore’s Law and its profound influence, whose link was shared. Today, two decades later, I remain in awe of how one man’s thought became a global technological doctrine. Moore’s Law is not just a law — it is a legacy, one that has empowered billions, connected continents, and continues to inspire.
As we
enter a future defined by AI, quantum breakthroughs, and post-silicon
paradigms, let us honour Gordon Moore — the visionary whose law continues to
shape our digital destiny.

World Heritage Day 2025: The Rail Heritage of Mumbai from Nehru Science Centre, Mumbai’s collections.
Every year April 18 is observed as the World Heritage Day. This day is also commemorated as the ‘International Day for Monuments and Sites’. It was in 1982, that UNESCO, during its 22nd General Conference held in Paris from 21-24 June, adopted a resolution to celebrate this day - 18 April - as the ‘International Day for Monuments and Sites’. The first World Heritage Day was celebrated on April 18, 1983. Thereafter, each year the international Council of Monuments and Sites (ICOMOS) proposes a theme for the commemoration of this day. This year the theme for the International Day for Monuments and Sites is “Heritage under Threat from Disasters and Conflicts: Preparedness and Learning from 60 Years of ICOMOS Actions”.

https://khened.blogspot.com/2020/04/the-majesty-of-ibrahim-rauza-monument.html
The main objective for commemorating
this day is to educate and sensitise people about the significance of heritage
including old monuments and sites, which are our common heritage that we have
inherited from our ancestors and we owe preserving these monuments and sites
for our future generations. Heritage
that refers to something that is inherited from the past, such as traditions,
customs, cultural practices, artefacts, historical buildings, monuments and
site, natural landscapes, etc. is our legacy from the past, which has been
passed down from previous generations and is often considered to be of
significant value or importance to a particular group of people or society as a
whole. Heritage is typically seen as a way to preserve and celebrate a
community's history and identity, as well as to promote the understanding and
appreciation of our cultural diversity. The monuments, sites and such other
edifices and other tangible and intangible cultural heritage and identity in
which we live today is our common Heritage that we have inherited and it is the
one that we must religiously pass on to our future generations.
The Rail heritage of Mumbai is inextricably linked to the Chhatrapati Shivaji Maharaj Terminus (CSMT) building in Mumbai. CSMT is individually listed as a World Heritage Site by UNESCO. This 19th-century majestic building is now the headquarters of the Central Railway. It was christened originally as the Victoria Terminus (VT), in honour of the then reigning British Queen, Victoria, and it continues to be the most famous architectural landmark of Mumbai. The VT building also served as the headquarters of the Great Indian Peninsular Railways (GIPR), the predecessor of the Indian Railways.
Railway transport has been a life line for Mumbaikars and the Nehru Science Centre Mumbai is in proud possession of some of the historic Rail heritage locomotives – Steam and Electric locomotive – and also a Steam Lorry. It also has in its collection Marut fighter aircraft, which were all restored to their majestic best during Covid. On this occasion of World Heritage Day, I am happy to share the links of three blogs which chronicle the history these three important collections of Nehru Science Centre, Mumbai for the leisure reading of those who it may interest.

GIPR had a share capital
of 50,000 Pounds when it was incorporated. On August 17, 1849, it entered into
a formal contract with the East India Company for the construction and
operation of an experimental rail line, 56 km long. The construction and
operation of the first passenger railway in India, 16th April 1853 in Mumbai,
received global headlines and attention. A report of the historic first train
journey says that “large groups of people had gathered along the two sides of
the railway track from Bori Bunder to Thane on the inaugural day of the steam
engine-driven locomotive”. It was almost some kind of a dream for the people to
witness a carriage running without harnessing animal or human power.
The black beauty steam
railway engine appeared like a mythical creature that was spewing out white
smoke as it moved ahead at speed, which was inconceivable at that time. Very
soon, the scientific principle of the steam-operated machines and their power
was understood, and the steam power was put to wide use in setting up industries
or looms, or even the early road transports like the Steam Waggon and cars that
reshaped Bombay’s geography in those early years. Steam locomotives in Mumbai soon
gave way to electric locomotives.
British engineers
received wide acclaim for the Railway line they had constructed and for the commissioning
of the rail transport in India. The global media hailed their accomplishments
of building a railway line in a tropical country like India, with varied
problems that ranged from snakes and animals to building embankments over
difficult stretches.
Three decades after the
inaugural rail transport in Bombay, the old wooden structure of Bori Bunder was
pulled down and replaced with a new station called Bombay Passenger Station. In
the meantime, the Britishers started a mega plan to construct a massive
terminus, which was then christened Victoria Terminus - VT.
The construction of the
VT station began in 1878, and ten years later, in May 1888, the majestic
building of VT (CSMT now) that we see today was completed for Rs 16, 35 562.
The building was very unique and was something the citizens of Bombay had never
seen before. The construction and operation of Railways had proved the
engineering skills of British Engineers, which was further exemplified by the
construction of the majestic VT building. The VT building was designed by the
consulting British architect, Frederick William Stevens. He has to his credit the
design of some other noteworthy Gothic Heritage buildings in Mumbai, which
include, among others, the Bombay Municipal Corporation building, the Royal
Alfred Sailor’s Home, and the Post-Office Mews at Apollo Bunder. The CSMT
building continues to be an engineering marvel even to this day.
The railways also brought
about a social revolution in Bombay with scores of workers travelling from
different parts of India to Bombay to be a part of the industrial growth, which
Bombay was witnessing.
The legend of Bombay as a
city of textile mills and Indian cinema began with the introduction of
Railways, which attracted masses from across the country to the city to work as
labourers or for leisure. The elegant CSMT building has symbolically
represented the cosmopolitan character of the city, which witnesses the travel
of diverse people and ideas.

Eulogy for Manoj Kumar: The Eternal “Bharat” of Indian Cinema.

Early this morning, Friday, 4 April, 2025, around 3.30 AM, a veteran Bollywood actor and director Manoj Kumar, popularly referred to as 'Bharat Kumar' for his classic patriotic films, passed away at the age of 87 at the Kokilaben Dhirubhai Ambani Hospital, very close to a place where I stay in Mumbai. He leaves behind a legacy of cinema steeped in nationalism and social issues.
Manoj Kumar, known to millions, particularly to people of my generation, as "Bharat Kumar," he was more than an actor, director, or filmmaker—he was a beacon of patriotism, a storyteller of social causes, and a mirror to a nation finding its footing in the wake of independence. His passing marks the end of an era, but his legacy, woven into the fabric of Indian cinema, will endure forever.
While paying homage to Manoj Kumar in our class group, “Tigers 77”, group of class buddies of Sainik School Bijapur who passed out of the school in 1977, one nostalgic memory of how Manoj Kumar had become an icon for most of us was remembered by Krishnamurthy Thakur, our buddy. He reminded us of how the most innocent of us all, a Gandhian of a sort, Pramod Deshpande ( Pammya to all of us) had bunked the Puri NCC Camp to see “Roti Kapada or Makan” film and that too in a alien place in Orissa in 1973. Such was the impact that Manoj Kumar had on most of us at that impressionable age. Other friends too spoke of their bunking experience in school to see his films, the most famous being Upkar.
Manoj Kumar was born on July 24, 1937, in Abbottabad, in undivided India. This place is now famous as a hideout of Osama Bin Laden, the mastermind of September 11, 2001, terrorist attack, which is now in Pakistan. The notorious, 54-year-old leader of Al Qaeda, the terrorist network of Islamic extremists, had been in hiding in Abbottabad, Pakistan before he was killed during a raid in two Black Hawk helicopters by US Navy SEALs on May 1, 2011.
Manoj Kumar was born as Harikrishna Giri Goswami and was one of those millions of people who became victim of the partition, and his life was therefore shaped by the horrific experience of the partition and the scar that left behind on his young mind. At the age of 10, the young Harikrishna had to leave his home empty handed to arrive in Delhi as a refugee, carrying with him the resilience and spirit that would later define his cinematic journey. Inspired by the legendary Dilip Kumar, he adopted the name "Manoj" and stepped into Bollywood with dreams that would soon transcend the screen. From humble beginnings in films like Fashion (1957), where he played a 90-year-old beggar, to his rise as a leading man in Hariyali Aur Raasta (1962) and Woh Kaun Thi (1964), Manoj Kumar showcased his versatility. But it was his patriotic fervor that truly set him apart.
Manoj Kumar’s defining moment came with Upkar (1967), a film born from a personal request by then-Prime Minister Lal Bahadur Shastri. Shatri ji had taken the mantle of the Prime Minister post in trying circumstances when the nation was passing through a period of a humiliating defeat against the Chinese in the 1962 war and was passing through a period of food scarcity and our hostile neighbours, Pakistan had chosen this tumultuous period to wage a war against us. Shastri ji excelled in raising to the occasion and made a clarion call to the nation coining a slogan “ Jai Jawan Jai Kisan “ which reverberated across nation hailing the Jawans and Kisans who rose up to the occasion to combat the situation. Shastri ji’s Jai Jawan Jai Kisan slogan was immortalised in Manoj Kumar’s film Upkar.
Moved by Kumar’s portrayal of Bhagat Singh in Shaheed (1965), Shastri ji appealed to Manoj Kumar to create a cinematic tribute to the slogan "Jai Jawan, Jai Kisan." And the result was Upkar. In Upkar, Manoj Kumar became Bharat—a farmer and soldier embodying the soul of a newly independent India. The film’s iconic song, "Mere Desh Ki Dharti," still echoes through our schools and hearts, a timeless anthem of pride and unity. Manoj Kumar poured his soul into this project, even selling his own property to fund the film, earning him the National Film Award for Second Best Feature Film and his first Filmfare Best Director Award. It was here that "Bharat Kumar" was born—not just a nickname, but a mantle he carried with grace and responsibility all through his cinematic life and beyond.
This was no fleeting role. Manoj Kumar embraced the name Bharat in multiple films—Purab Aur Paschim (1970), Roti Kapda Aur Makaan (1974), and beyond—each time portraying a man of unwavering principles, standing tall amid cultural clashes, economic struggles, and the fight for dignity. In Purab Aur Paschim, Bharat bridged East and West, championing Indian values in a rapidly globalizing world. Today when we celebrate the sociocultural uniqueness of India, and its identity globally, we must credit Manoj Kumar who instilled the spirit of the nation, Bharat.
In Roti Kapda Aur Makaan, he tackled unemployment and corruption, reflecting the hardships of a nation reliant on foreign aid like the USA’s PL 480 scheme—a program that provided wheat to feed India’s citizens during the food crises of the 1960s. Through these films, Manoj Kumar and his contemporaries, like Dilip Kumar and Raj Kapoor, harnessed cinema’s soft power to inspire a country awakening to its freedom while grappling with poverty and dependence.
Yet, Manoj Kumar’s genius wasn’t limited to patriotism. His 1972 film Shor revealed a tender side—a father’s anguished quest to restore his mute son’s voice, brought to life with the haunting melody "Ek Pyar Ka Nagma Hai." It was a masterpiece of emotion, proving that his artistry could touch the personal as profoundly as the national. This film resonates so well with yours truly even today, reminding of the challenges that parents of differently abled children face, which I have faced and continuing to face. Then there are other films of grand spectacle, a quintessential attribute of Bollywood, like Kranti (1981), where he brought in Dilip Kumar, Hema Malini, and Shashi Kapoor to depict India’s fight for independence, he balanced scale and grandeur with soul, reportedly selling his Juhu bungalow to realize his vision. Such was his commitment—to art, to nation and to the cause of Bharat which he truly believed and lived all his life.
In an India navigating its post-independence identity, Manoj Kumar and his ilk—filmmakers of grit and conscience—used cinema to reflect social causes and instill patriotism. The 1960s and 70s were tough times: wars with China and Pakistan, food shortages, and a reliance on foreign aid tested the nation’s spirit. Yet, through films like Shaheed, Upkar, and Roti Kapda Aur Makaan, Manoj Kumar reminded us of our strength, our values, and our unity. His characters weren’t just heroes; they were us, the common people - farmers, soldiers, fathers—striving for a better tomorrow.
His contributions earned him the Padma Shri in 1992 and the Dadasaheb Phalke Award in 2015, honours that pale beside the love of generations who grew up watching his films at school, singing his songs on Independence Day, and feeling the swell of pride he so effortlessly evoked. Today, as we mourn his passing at Kokilaben Dhirubhai Ambani Hospital due to cardiogenic shock and liver cirrhosis, we also celebrate a life that gave us purpose. Manoj Kumar once said, "Patriotism is in my blood," and he lived that truth, leaving behind a legacy that will inspire filmmakers, actors, and citizens alike.
To us at school, his films were more than entertainment—they were lessons in courage, identity, and love for our country, which is deeply etched in all our lives. As we say goodbye to Bharat Kumar, we know he doesn’t truly leave us. He lives on in every note of "Mere Desh Ki Dharti," in every frame of Shor’s quiet beauty, and in the enduring spirit of a nation he helped shape.
Om Shanti. Rest in peace, Manoj Kumar—your Bharat will forever stand tall.
