Technology Then and Now…The Biggest Impacts of the Last 20 Years

Take a tech-friendly trip down memory lane circa 2002: Napster filed for bankruptcy months before the Linkedin.com domain name was created;  the minds at M.I.T. sent the Roomba across household floors; while NASA got the wheels moving on a different type of ground-based robot — the MARS Rovers. 

It’s hard to believe how dramatically the landscape of technology changed since the dawn of the millennium. Even the software and hardware created from 2002-2011 and 2012-2022 can feel generations-removed from their parent concepts. Case in point: wireless wearable technology like Fitbit allowed software to engage with us in the real world, then virtual reality encouraged us to engage with technology in the virtual world. 

From AR to AI and so many innovative inventions in between, let’s look at some of the hardware and software created in the last twenty years that have impacted the world in profound ways. 

Cloud-Based Storage

A millennial nightmare summed up in a single action — forgetting to click “save” on a Microsoft Word document before exiting the program — students and professionals alike dreaded the scenario. Auto-save was helpful, as were document-recovery protocols. And there’s also no denying that flash-drives saved the day for countless individuals who found themselves helpless during a hard-drive crash. 

But cloud-based storage changed the data-saving game in the most extreme way. 

Not only is data accessible at any time and protected by the latest IT securities but remembering to save data has become a thing of the past. Automatic and manual syncing ensures data is backed up consistently. The ability to edit living files in real-time with other users, and have all changes saved and recorded instantaneously, is a vital resource that few professionals could function without today.


Millennials know all too well the dangers of the internet; their indoctrination to the world-wide web occurred as they matured into adults. Instead of facing scams, data breaches, and other threats first-hand, many watched instead as the generation preceding them fell victim to these malicious acts. 

It comes as no surprise then that blockchain technology has grown immensely in popularity since the first implementation in 2008. Whether it be cryptocurrency or property deeds, the system’s near- impossibility to be changed, hacked, or otherwise maliciously edited is the key takeaway. With companies like IBM investigating ways of integrating blockchain ledgers into their cloud-based applications, blockchain technology will revolutionize how data is stored, secured and, most importantly, verified as legitimate. 

Mobile Operating Systems

One would be remiss to not mention social media as one of the greatest inventions of the last 20 years, but the true unsung hero in social media’s dominance — as well as the driving factor in the success of many other applications — is the rise of mobile operating systems. 

While the IBM Simon Personal Communicator of the 1990s was the first conceptual smartphone, the smartphones of today would be nothing without their mobile operating systems. iOS, Windows Mobile, Android, WebOS, and others have paved the way for portable computing. Myspace and AOL Instant Messenger proved that social media would still thrive without portability, but it’s the mobile operating systems that have accelerated and amplified social media usage to unfathomable levels. It’s almost impossible to imagine a world without Facebook, Instagram, and TikTok commanding so much of the average user’s attention. 

The mobile operating system hasn’t replaced the personal computer, but it has revolutionized the ways in which people accomplish their daily tasks via the internet. Mobile operating systems keep us connected to the world wherever we go. It’s more than a computer in our pocket — it’s all our resources, desires, and necessities, readily available with the tap of a finger. 


Apple is an elite company whose contributions to the world of technology are immense. Inventing the iPod and the iPad are both significant accomplishments, though it’s hard to argue that there was no product more revolutionary in the millennium than the release of the iPhone. Its operating system, functionality, and wealth of applications need not be discussed; the iPhone’s most profound impact transcended technology itself and integrated the device into mainstream culture.

An iPhone is as much a personal device as it is a personal statement. Consumers continue to covet the latest iPhone release, even if its technological specifications do not exceed the capabilities of similar devices from other brands. Android and Google both have significant followings, but history will show that it’s Apple’s iPhone that captured the zeitgeist of the early millennium. 

Self-Driving Car

AI and machine-learning are inarguably the future of technology, and the self-driving car is perhaps the most important example of why this tech will revolutionize the world. Driverless technology has the potential to change the way the world relies on transportation-based services. It’s beyond moving a single person from place to place; autonomous vehicles on land, sea, and — eventually — air could restructure the global supply chain in ways that reduce energy output and limit the need for manual operation. 

Tech in Twenty Years

The question isn’t if these technologies will endure for another 20 years, but rather, how they will interact with the century’s yet-to-be-introduced hardware and software. 

What will 2042 look like, now that self-driving cars, at-home 3D printing, and decentralized currency are integrating themselves into daily life? Social media will almost certainly continue to dominate the landscape, but how will emerging players compete in an arena — physical and metaverse — where possibilities are as limitless as our imaginations?

Such questions and their answers are ultimately meaningless if these technologies are not leveraged to their fullest potentials. Whether these innovations change the fabric of our society forever (or act as nothing more than a trendy novelty) depends on the business leaders and entrepreneurs of tomorrow. Technology is ultimately nothing more than a tool that requires brilliant, creative, and disciplined minds in order to yield appropriate results.
