Computing and innovation are in perpetual motion. To truly understand today’s technology and anticipate what comes next, historical perspective is essential. The early evolution of personal computers (PCs) set the stage—from the development of networking and UNIX, to the explosive growth of the Internet and cloud computing. These foundational technologies not only shaped today’s digital world but also prepared us for the era of artificial intelligence (AI).

The transformation from mainframes and minicomputers to the affordable, personal computer democratized access to computing power. UNIX’s foundational design is still present in today’s macOS, Linux, and Chrome OS. Thanks to visionaries, what was once room-sized now fits in a pocket and connects to global resources.
The Digibarn Museum and tours by figures like Steve Wozniak help illuminate this revolutionary leap. It’s a living timeline of the open architectures, early operating systems, and networking breakthroughs that fueled modern innovation.
The Present: Cloud, Connectivity, and Accelerating Change
The AT&T “You Will” campaign (1993) got many things right, such as smartwatches, video calls, and telemedicine, all realized through powerful mobile devices, cloud computing, and high-speed global networks. Still, the forces driving these changes have often come from unexpected corners—startups, open source communities, and cross-disciplinary collaboration.
Today, daily life depends on always-connected devices and seamless cloud services. PC power keeps moving to the cloud, putting almost limitless capacity within reach and reshaping how productivity, entertainment, and communication work. Watch these ads from 1993 and think about where we are now:
The Future: AI, Quantum and the End of the “Personal Computer”
We now stand at the threshold of a new wave: artificial intelligence and quantum computing are reshaping what’s possible. Modern AI models already handle complex language, vision, and decision tasks once thought exclusive to people. Workflows across medicine, research, logistics, farming, and education are being transformed by intelligent assistance, automation, and predictive analytics.
Personalized AI agents anticipate needs and adapt dynamically, often removing friction from everyday systems. The notion of a “personal computer” is evolving toward cloud-backed interfaces—simply points of access for users to interact with vast AI-powered ecosystems. Quantum computing promises new forms of problem-solving and security but raises as many questions as it answers about readiness and risk.
AI and Disintermediation
Whereas the Internet once disintermediated entire industries by connecting suppliers directly to consumers, AI now extends this disruption. Work that required technical specialists is becoming accessible via natural language: coding, design, research, even legal and medical guidance. This reshapes professional roles, education pathways, and business models at a stunning pace.
Paradigm Shift
As IT professionals we cannot be complacent. The velocity of change is profound, and affects every single one of us and our future in IT. We must continue to learn, and we must continue to monitor IT news and IT trends. Some of you may have been around before the first cell phone or personal computer was commonplace. Even if you weren't, it is hard to escape noticing how fast things are changing in our lives, in our society, in our education and in our careers. How do we keep up? Can we stay relevant and innovative?
Staying Relevant: Lifelong Learning and Ethical Adaptation
The “paradigm shift” is faster than ever, demanding agile mindsets and ongoing education. New ethical challenges—especially around AI bias, privacy, and transparency—require vigilance and public dialogue. As John Hennessy and leading engineers advise, only those who continually learn and monitor trends can thrive and help steer technology toward broadly beneficial outcomes.
In summary: The journey from mainframes to AI is a story of acceleration—with each era building upon the last, exponential in its reach and influence. For educators, technologists, and the curious public, reflecting on this arc is both necessary and inspiring. The future will demand constant learning and ethical innovation; fortunately, the history of computing suggests that openness and adaptability are our greatest tools.

The Future of Retailing
There are some amazing technologies that enhance shopping. When you read this report and watch this video, think about the potential for IT professionals and how you might fit in areas of specialty such as retail.
The AT&T adds were amazingly accurate! I remember some of those commercials and I can't believe how much has been achieved since 1993.
