Consider the year 1996. That’s twenty years ago. Multimedia was in its infancy. There was no Google, no social media. Electric vehicles were a dream. Amazon had just started. The Human Genome Project was underway.

In his book Visions: How Science will Revolutionize the 21st Century (1997), Michio Kaku, acclaimed theoretical physicist and string field theory co-founder, discussed the status of science in 1996 and made several predictions for how the world would look in 2020 and even later. As the host of a TV show, he spoke to nearly 150 scientists and technologists on what the near and distant future holds.

Reading the book now, it becomes clear that he got many things spot on. He talked about how microprocessors would become cheap, and computing pervasive. With a flourishing mobile revolution worldwide and chips in refrigerators, washing machines, playstations and so on, computing is indeed pervasive.

He was right about electric/hybrid vehicles and automated (driverless) cars. He was right about the Internet of Things. He was also right about the dominance of artificial intelligence and robotics. He also predicted the advent of internet glasses; there is now, for instance, the Google Glass.

Kaku says the twentieth century saw three scientific revolutions: the computer revolution, the quantum revolution and the biomolecular revolution. By 2020, a new era would be heralded, one of synergy between the three revolutions. This is indeed happening. Bioinformatics is an example of synergy between the biomolecular revolution and the computer revolution, resulting in automated gene-sequencing and genotype/phenotype matching. Advances in magnetic resonance imaging is a synergy between the biomolecular revolution and the quantum revolution. Visions is an engrossing read even now, twenty years later.

In 2011, Kaku again spoke to 300 scientists and technologists, and came up with another book. Physics of the Future: The Inventions That Will Transform Our Lives (2011) is a futuristic look at progress in science till the year 2100 AD. He says,

I hope this book will give an insider’s perspective on what miraculous discoveries await us and provide the most authentic, authoritative look into the world of 2100.

Kaku covers the entire gamut of science (not just physics), including information technology, artificial intelligence, medicine, nanotechnology, energy and space travel. At the end of the book, he provides a tantalising glimpse into a day in January 2100.

Some of his predictions are mind-blowing. For instance, he claims that by 2100, telepathy (mind-to-mind communication) and telekinesis (moving objects by means of the mind) will be possible. Recently scientists have been able to record dreams and even upload thoughts into a rat’s brain. And as Kaku writes, paralysed people have been hooked up to computers and are able to control cursor movements through their thoughts. So his claims may not seem far-fetched. Maybe, as he says, “By 2100, our destiny is to become like the gods we once worshipped and feared.”

Since energy is one of the specialisations of this writer, here are some points about Kaku’s predictions on energy.

Kaku believes that by 2100, we would have succeeded in harnessing fusion power, which would supply us with unlimited energy for our needs. We may be able to develop room-temperature superconductors by then, which could be used to build roads on which our (driverless) cars could float (move without friction), and at very high speeds. Since a lot of energy is expended currently in overcoming the friction on roads, high-temperature superconductors can drastically reduce energy consumption.

By then, we would also be capable of “sending hundreds of space satellites into orbit around the earth, absorbing radiation from the sun, and then beaming this energy down to earth in the form of microwave radiation.”

Kaku’s book, like his predictions, is miraculous. This writer has a twinge of regret that he would not live to see these changes occur by 2100.

We live in an inflection point in history, and, if futurist Ray Kurzweil is right, in the proximity of a singularity. It is quite probable that we will witness some enormous upheavals in our way of life.

  • Darknet


    Darknet, also known as dark web or darknet market, refers to the part of the internet that is not indexed or accessible through traditional search engines. It is a network of private and encrypted websites that cannot be accessed through regular web browsers and requires special software and configuration to access.

    The darknet is often associated with illegal activities such as drug trafficking, weapon sales, and hacking services, although not all sites on the darknet are illegal.


    Examples of darknet markets include Silk Road, AlphaBay, and Dream Market, which were all shut down by law enforcement agencies in recent years.

    These marketplaces operate similarly to e-commerce websites, with vendors selling various illegal goods and services, such as drugs, counterfeit documents, and hacking tools, and buyers paying with cryptocurrency for their purchases.

    Pros :

    • Anonymity: Darknet allows users to communicate and transact with each other anonymously. Users can maintain their privacy and avoid being tracked by law enforcement agencies or other entities.
    • Access to Information: The darknet provides access to information and resources that may be otherwise unavailable or censored on the regular internet. This can include political or sensitive information that is not allowed to be disseminated through other channels.
    • Freedom of Speech: The darknet can be a platform for free speech, as users are able to express their opinions and ideas without fear of censorship or retribution.
    • Secure Communication: Darknet sites are encrypted, which means that communication between users is secure and cannot be intercepted by third parties.


    • Illegal Activities: Many darknet sites are associated with illegal activities, such as drug trafficking, weapon sales, and hacking services. Such activities can attract criminals and expose users to serious legal risks.
    • Scams: The darknet is a hotbed for scams, with many fake vendors and websites that aim to steal users’ personal information and cryptocurrency. The lack of regulation and oversight on the darknet means that users must be cautious when conducting transactions.
    • Security Risks: The use of the darknet can expose users to malware and other security risks, as many sites are not properly secured or monitored. Users may also be vulnerable to hacking or phishing attacks.
    • Stigma: The association of the darknet with illegal activities has created a stigma that may deter some users from using it for legitimate purposes.
