Futurists of the 1950s and '60s predicted that by the 2000s, flying cars and airborne robots would be a part of our everyday lives. Instead, we live in a world dominated by live streaming, smartphones and social networks.

While those forecasters didn't quite get the timing right, they got the technology right. Today, we are at the brink of another technological boom. This time, technologies like self-driving vehicles and robot assistants are under development. Soon, these and the other exciting technologies described below will go mainstream, changing the world in the process.

1. Voice assistants
In four years, the majority of American households are expected to own a voice assistant device like an Amazon Echo or an Apple Homepod. Thanks to the power of artificial intelligence (AI), voice assistants will grow increasingly helpful.

Even today, Amazon releases regular updates to Echo in order to help owners get more from the technology. The company recently reported seeing larger-than-expected gains from its voice assistant, which is why Amazon is now doubling down on the technology.

Voice assistants are making a significant impact in markets across the globe, and some observers expect that in the future we will communicate with technology through voice rather than text.


2. Robot assistants

Companies like Boston Dynamics have already developed a wide variety of robot assistants that can be used in factories or on the battlefield. The company originally started as an arm of MIT and has since pioneered the development of intelligent robots that operate effectively in the real world.

Knightscope is another company working on a line of robot assistants for security applications. For example, its K5 robot features four cameras and can recognize 300 licenses plates per minute, per camera. It can also detect suspicious networks that may be operated by hackers.

3. Regenerative medicine
Though it may sound like science fiction, doctors are already producing made-to-order body parts. To get started, doctors scrape cells off the body part in question and grow them in a petri dish. In time, the body part grows strong enough that it can be implanted inside the patient.
One company, Organovo, has developed a printer capable of 3D printing body parts. In time, this new technology will become increasingly mainstream, providing patients with lifesaving organ replacements.

And when will Terminators start replacing our soldier boys on frontline?
At least we'd have our boys in their barracks controlling the robots in war. Then there'd be more peace since all will be more like video games.
Whoever cannot buy more robots loses.
