Best Tech Inventions of the 21st Century that will Transform our World

Tech Inventions of the 21st Century

We can envision the future by observing the present and making predictions about the future of humanity based on the technologies that are getting the most attention today. In the first half of the 21s century, we are already seeing the advancement of world-changing technologies that will shape the centuries ahead of us.

Here is our compiled list of the best tech invention of the 21st century that are most likely to transform our world fundamentally.


The closest humanity has gotten so far to engineering and influencing organic matter, and the potential is massive.

Genetic modification of organic matter will have a drastic and far-reaching impact on almost every aspect of human life.

Personalized medication, cell therapies, and stem cell treatments have the potential to transform the way we deal with genetically defined diseases, cancer, and much more.

3D printing

You probably expected to see this one on the list. 3D printing merges manufacturing with the trend of decentralization and personalization that we see so often in the 21st century. Instead of relying on specialized suppliers or long and complicated supply chains subject to geopolitical changes to deliver resources, all you need is a blueprint, raw materials, and a machine.

It is empowering for a creator to be able to sell their creation to someone across the planet just by uploading a file to a 3D printing marketplace. Whether it be for a house, trinkets, and even artificial organs that are well on the way to becoming commonplace in the medical world, we can only begin to imagine the future potential of additive manufacturing.


Perhaps at the top of the most important inventions of the 21st century, blockchain technology takes out the digitized world and gives it a real backbone.

Many describe the creation of blockchain technology as an evolution rather than a revolution, although the implications may as well be revolutionary. Secure and virtually verifiable identification, anti-blackout information systems, and monetary exchange without the need for a middle-man all have become possible with the invention and continued improvement of blockchain technology.

The cryptocurrency and NFT hype of the past few years will eventually calm down, but decentralized ledgers are here to stay and have more to offer than given credit today.

Virtual and Augmented Reality

To first draw distinction, Virtual Reality (VR) differs from Augmented reality (AR) in that VR displays an entirely separate virtual world and seeks to isolate the user from the outer world for as much immersion as possible. For this reason, VR’s potentials seem to be most prominent in the entertainment industry and possibly education.

AR, on the other hand, seeks to put a virtual overlay over the real world to improve data relay. The potential of AR goes far beyond entertainment and into more practical and specialized applications. Applied virtual training programs, virtual interfaces that take your phone out of your pocket and put it at the tip of your nose. This allows for uses and information relay such as highlighted maps directions, location names, weather, breaking news, item descriptions, and much more.

Multi-use Rockets

If there is one thing that will propel humanity into the space age, it’s the invention of multi-use rockers. Among the greatest inventions of the 21st century, brought to us by the world-renowned billionaire entrepreneur Elon Musk, reusable rockets allow for a sustained method of space transportation. Now space travel companies can recover and reuse launched rocket parts instead of discarding them after a single use and letting them sink into the ocean’s depths.

This is the first step in the direction of multi-planetary human occupation and unlocks the potential for further space industries to emerge.

It’s a brave new world, and it only gets braver as we continually push the frontiers of human ingenuity. We have the privilege of witnessing the greatest technological advancements of the 21st century in their infancy, and if our history has taught us anything, it’s that change happens fast, and technological advancement is exponential.


Of all the best tech inventions of the 21st century, the five mentioned in this list will most likely have the most substantial impact on the future of humanity.
