So many things have happened to completely change – not just America but the world – since we, the baby boomers, have been alive.

In 1973 I was a Junior at Rutgers University in New Jersey when a classmate came up to me and showed me a Texas Instrument CALCULATOR! and I asked him “What’s that?”

“Its a Calculator!” he answered. “What does that do?” I asked him. He answered “Well, it adds, subtracts, multiplies AND divides” he said. I then asked him “Really? Is that thing any good? Is it precise?” and he said “Yes,” to which I answered “I think that I will stick with my slide rule!” (Does anyone remember what a “slide rule” was?).

As baby boomers, these are among the many marvels that have happened to the world DURING OUR LIFETIMES!

These days no one thinks anything of the powerful cell phone that they have in their pockets, but in 1973 such a thing was as much fiction as Dick Tracy’s wrist watch phone! (see below my blog on Dick Tracy)

The year 1971 marked a tremendous moment in the history of computing – and in the history of the world – with the discovery of the microprocessor. This tiny, yet powerful invention laid the foundation for the modern digital age, revolutionizing not only the way we compute but also shaping industries, economies, and societies worldwide.

The microprocessor, often referred to as the “brain” of a computer, is a small integrated circuit that contains the central processing unit (CPU), memory, and other essential components necessary for processing data and executing instructions. Its discovery is credited to a team of engineers at Intel Corporation, led by Marcian “Ted” Hoff, Federico Faggin, and Stanley Mazor. Although there are others who also credit scientists at Texas Instruments for, in September of 1971, as well having discovered the microprocessor.

Prior to the microprocessor, computers were HUGE, expensive machines reserved for government, research institutions, and large corporations. They were built using discrete components such as vacuum tubes, transistors, and diodes, occupying entire rooms and requiring extensive cooling systems to operate. The introduction of the microprocessor changed things completely by condensing the computing power of these massive machines into a single, small chip.

The breakthrough moment came with the release of the Intel 4004, the world’s first commercially available microprocessor. Developed for a Japanese calculator manufacturer, the Intel 4004 boasted a mere 2,300 transistors and ran at a clock speed of 740 kHz. Despite its modest specifications by today’s standards, the Intel 4004 represented a monumental leap forward in computing technology.

One of the key advantages of the microprocessor was its versatility. Unlike previous computing systems, which were designed for specific tasks and applications, the microprocessor could be programmed to perform a wide range of functions. This flexibility opened up endless possibilities for innovation, paving the way for the development of personal computers, gaming consoles, mobile devices, and countless other digital technologies that have become ubiquitous in modern life.

The impact of the microprocessor extended far beyond the realm of computing. Its compact size and low-cost democratized access to computing power, enabling every day individuals and small businesses to be able to use technology in ways that were previously unimaginable. This democratization of computing sparked a wave of innovation and entrepreneurship, giving rise to the tech industry that we know today.

Furthermore, the microprocessor played a crucial role in driving economic growth and competitiveness on a global scale. Countries that embraced this technology and invested in research and development reaped the benefits of increased productivity, job creation, and technological advancement. The United States, in particular, emerged as a leader in the semiconductor industry, with companies like Intel, AMD, and Texas Instruments dominating the market.

Moreover, the microprocessor revolutionized communication and connectivity, laying the groundwork for the digital revolution. The proliferation of microprocessor-based devices facilitated the rapid exchange of information, breaking down barriers of time and space and connecting people across the globe. This interconnectedness has transformed every aspect of society, from how we work and communicate to how we learn and entertain ourselves.

In conclusion, the discovery of the microprocessor in 1971 IN OUR LIFETIME was a key moment in the history of computing. Its invention ushered in a new era of innovation, empowerment, and connectivity, shaping the world we live in today. As we continue to push the boundaries of technology, it is essential to reflect on the profound impact of this tiny yet transformative invention and the countless possibilities it has unlocked for future generations.
