Blockchain
By this point, we have all heard how
blockchain technology is revolutionizing virtually every business
conceivable. A decentralized digital ledger that tracks information and
maintains it in several locations, making forgery difficult, may
theoretically be useful for banking, politics, healthcare, and other
industries. Identity is supplied by intricate computations, which also
makes identity theft very impossible.
But in the aforementioned
description, one word leaps out: Decentralised. Institutions like banks,
governments, and hospitals don't want their authority to be limited
(unless on their own terms). As a result, it is probable that we will
see some developments in the blockchain field, but it will continue to
exist at the periphery of technology and fall short of the revolution
that its supporters had hoped for.
Quantum computing
Initial considerations: The emergence of the quantum computer has been foreseen by scientists for more than 50 years. But this could be the last time. Google was able to finish a calculation that would have taken a conventional supercomputer 10,000 years to complete in just three minutes, according to an announcement made in October 2019 asserting that the company had attained quantum supremacy (the ability of a quantum computer to perform better than a conventional computer on a given task). According to IBM, who disputes the accuracy of these numbers, a typical computer program could have resolved the issue in just 2.5 days.
In theory, quantum computers are much faster and more effective than their older brothers, but they frequently experience decoherence problems because they use qubits with superimposable states (for example, a 0 can also be a 1 at the same time) (loss of information). However, creating them for pharmaceutical firms, for instance, might theoretically result in significant advancements in, among other things, the production of medicines.
Self driving vehicles/Autonomous vehicles
Keep in mind that there are, in general, 5 levels of autonomous driving, from "no automation" to "full automation." While levels 0 to 2 require close human supervision, levels 3 to 5 rely on computers to monitor the driving environment. The most sophisticated autonomous cars now available can operate at levels 3 and 4. (Tesla). We ought to be able to accomplish level 5 by 2025, if not sooner (and complete driving automation). But there is still a long way to go because the industry is still plagued by issues like moral quandaries and statistical issues.
Even if level 5 is attained, it's possible that we will never really replace automobiles as we know them, preferring to designate certain lanes of traffic and parking areas for autonomous vehicles in order to prevent collisions between the two. In fact, the automobile as we currently know it is so essential to our lives that altering it could require redesigning most of our everyday world: parking would become less significant, charging stations would shift, and how pedestrians interact with safer roadways would be permanently changed.
5G
With substantially faster speeds possible because to higher-frequency radio waves, 5G is the obvious successor to 4G. Even if it sounds straightforward, there are a few concepts that must be grasped in order to truly appreciate how challenging it is to deploy 5G globally.
Small cell towers called microcells, femtocells, and picocells serve as relays in constrained spaces, as inside of big buildings. Due to the fact that 5G transfer distance is substantially shorter than 4G, as was previously said, this infrastructure is required (and struggles to go through thick walls).
A specific region of the radio frequency spectrum between 24GHz and 100GHz, with an extremely small wavelength, is referred to as the millimeter wave spectrum. This region of the spectrum is not only mostly untapped, but it can also carry data extremely quickly despite its shorter transfer distance.
All of these transfers must be planned and orchestrated for beam-forming. Making beams does this.
The capability of simultaneously sending and receiving data on the same frequency.
The technology will significantly alter the speed, volume, and quality of the connection as well as have a profound impact on the majority of businesses. It will enable significant advancements in virtual reality and IoT, among other things by connecting drones and driverless cars to the internet.

Nano-robots
Allow me to introduce nano-robots for those who wish to go even smaller than micro-chips. Nano-robots, which are now in the research and development stages in laboratories all around the world, are essentially very, very tiny sensors with very little computing power.
These nanomachines might very possibly find their first practical uses in nanomedicine. For instance, biological robots may be employed to locate and eliminate cancer cells or disperse medication. The detection of harmful substances and the assessment of their quantities in the environment are two more possible applications.
Low-earth orbit satellite systems
Internet-related thoughts Up to 42,000 satellites will be launched by SpaceX over the next five years to provide Internet access around the world. The OneWeb constellation, which intends to have 600 satellites by 2022, and Amazon's intentions to deploy 3,236 low-orbit satellites to cover white regions demonstrate that the business is not the only player in this market.
The minimal cost of launching these nano-satellites, which only weigh a few pounds, makes all of this conceivable. Additionally, fleet management would be much simpler and more hygienic at a lower height.
However, with so many devices in orbit, there are issues with collision risk, disruption of astronomical observation, and interference with other satellite services like weather.
