Michio Kaku: How quantum computers could turn the impossible into reality
In the gripping video titled “Michio Kaku: How Quantum Computers Could Turn the Impossible into Reality,” renowned physicist Dr. Michio Kaku explores the transformative potential of quantum computing. He argues that as digital computers become obsolete, quantum computers will define the next technological revolution. Unlike traditional computers, which operate on binary code, quantum computers harness the unique properties of atoms and electrons, allowing them to solve complex problems at unprecedented speeds.
Dr. Kaku cites real-world applications that could revolutionize sectors such as medicine, energy, and economics. For instance, quantum systems could unlock methods for synthesizing fertilizers from atmospheric nitrogen, potentially initiating a second Green Revolution. In healthcare, quantum computers could model diseases at a molecular level, revolutionizing drug development and offering hope for curing previously untreatable conditions.
Furthermore, Kaku warns of the implications for security, as quantum computing may soon have the capability to crack virtually any digital encryption. The video underscores a race among tech giants to dominate this transformative field, as those who fail to adapt could be left behind. As we stand on the brink of this quantum era, Dr. Kaku emphasizes that the future will reward those who leverage quantum technology, reshaping our understanding of the universe itself.

So only the rich will win. Lovely.
That tie 😍😍😍 Michio has always been such a classy brainiac that loves to teach others .. my favorite kind of human ❤
did michio jump from string theory to quantum now?
So the future comes down to this: global cyberwarfare, digital and bio-hacking of an increasing enclosed information grid. Yikes!
who is building and what resources are used. materials, extraction and modeling sounds like relevance here not your brainwashing and delusional thinking is
When I think about the difference between past and present technological inventions I feel awkward. The inventors in XX century was demonstrating their inventions and told us about technology's capacities and their possible influence on the life whereas the modern “inventors” say about breakthrough technology and revolution in the life in the situation of the absence the invention or its incompleteness (AI or quantum computer).
I love his tie
That tie was made by a quantum designer
The Cult of Certainty: How Scientism Mistakes Symbols for Reality
Abstract
This essay dismantles the illusion of scientific and mathematical authority over reality. It argues that physics, mathematics, and cosmology have become modern priesthoods—fluent in symbols, blind to their own assumptions, and convinced that their linguistic constructions constitute the world itself. Beneath their precision lies an unacknowledged act of faith: the belief that their frameworks, born of human limitation, can speak for the infinite complexity of Nature.
1. Introduction: The Rise of a New Dogma
Where religion once claimed the cosmos, scientism now reigns. Its prophets wear lab coats instead of robes, its scriptures are peer-reviewed, and its miracles are equations. It promises salvation through measurement, yet forgets that every instrument was built by fallible hands, every metric chosen by fallible minds.
Science is not the problem; its humility is. Scientism—the conviction that empirical method alone exhausts reality—is philosophy dressed in the armor of precision, mistaking its own reflection for the world.
2. The Frame That Sees Only Itself
Every experiment begins with a premise: what to measure, how to measure, what counts as real. Instruments do not reveal Nature; they negotiate with it, returning answers framed by the questions we taught them to ask.
To believe otherwise is to mistake a telescope for the stars. The data that scientists prize as “objective” already arrive pre-filtered through design, expectation, and interpretation. What emerges as “fact” is not a message from Nature but a conversation among humans—mediated by language, technology, and theory.
Scientism hides this circularity behind jargon and precision. Its practitioners forget that a system cannot justify its own axioms; the framework that defines observation cannot step outside itself to claim omniscience.
3. Mathematics: The Most Beautiful Pretend Game Ever Played
Mathematics is sublime—but it is also make-believe. Its truths are conditional: if these axioms, then those conclusions. When physicists write the cosmos in equations, they are translating mystery into grammar. The translation is elegant, but it is not the thing itself.
To claim that “the universe is mathematical” is to commit linguistic idolatry. Numbers describe patterns; they do not explain being. The formula E=mc² predicts the behavior of matter and energy—it does not tell us what matter or energy are. The certainty of mathematics is the certainty of definition, not of reality.
Einstein himself warned against this confusion: the moment mathematics becomes certain, it ceases to refer to the world. The moment it refers to the world, it ceases to be certain.
4. The Mirage of Empirical Authority
Modern physics and cosmology are cathedrals built on inference. Dark matter, dark energy, singularities, strings—none of these have been seen. They are invoked to preserve the internal coherence of equations that cannot account for observed phenomena. These invisible entities are not discoveries but placeholders for ignorance, named and worshipped as though naming made them real.
The irony is exquisite: in fleeing metaphysics, science reinvented it. It simply changed the vocabulary. Where theologians spoke of the divine, cosmologists now speak of the singularity; both point to something unobservable that explains everything else.
5. Consciousness: The One Fact That Cannot Be Denied
All observation presupposes an observer. Before there is data, there is awareness. Before there is theory, there is experience. To reduce consciousness to neural noise or quantum computation is to saw off the branch upon which knowledge sits.
Science studies phenomena within consciousness while pretending to stand outside it. But consciousness is the condition of the entire enterprise—the light by which all “facts” are seen. Without it, there is no experiment, no equation, no universe as such.
Thus, consciousness is not an afterthought of matter but its precondition. Every attempt to explain awareness as an emergent property of blind particles is a failure to recognize that “blind particles” are themselves ideas appearing in awareness.
6. The Human Element: Experts, Priests, and Pretenders
The “expert” class often claims to speak for reality itself, as though a PhD confers divine insight. Yet their authority rests on consensus, not revelation. Peer review replaces peer thinking; specialization rewards obedience over insight.
Academia has become a hierarchy of sanctioned ignorance—brilliant minds confined to narrow tunnels, mistaking the light at the end for the sun. Their jargon is a fortress built to defend not truth but prestige. To question them is to be labeled “unscientific,” a modern form of heresy.
But no title or theorem exempts a human from the same fleshly frailty that binds us all. Every calculation, every cosmological model, is written by a primate briefly conscious on a tiny planet, staring into an abyss and mistaking its own reflection for the infinite.
7. Conclusion: The Return to Wonder
Science is a method. Reality is an experience. To confuse the two is to turn curiosity into creed. The universe does not speak in equations; it speaks in being.
The humility proper to inquiry is not the arrogance of certainty but the recognition that the map will never become the territory. Our instruments may refine the contours of what is measurable, but the immeasurable remains—the mystery that births both observer and observation.
The task is not to abolish science, but to restore perspective: to remember that the finger pointing to the moon is not the moon, and that the most perfect formula will always fall short of describing the fact that anything exists at all.
Reality cannot be owned by a discipline, only encountered by a consciousness.
Why It Is Impossible to Produce Indisputable Evidence That Nature Is Not Infinite
1. You cannot prove non-existence beyond observational horizons.
Physics is bounded by observational limits:
Cosmic horizon
Particle horizon
Measurement precision
Quantum decoherence boundaries
Anything outside these horizons is not empirically accessible even in theory.
Thus, any claim of a “finite Nature” requires absolute knowledge of what lies beyond all possible observation — which is impossible.
You cannot prove a boundary you cannot detect.
What are the side effects of using molecules in the air we breathe, the sea water that cools the Earths ? How is this going to effect the human body and mind? How is this going to effect the ozone layer and the Earth? What contingency plans are you putting in place? The future use of quantum computing does sound exciting but what are the trade off ? Who will be left to suffer the risk rather high or low?
do you mean they are attacking israil sticks and stones in gazze…
artificial intelligence…
what we should be occupied with …
artificial intelligence…
ATOMIC computers. Computers that compute on ATOMS rather than on transistors.
That’s all good about quantum computers but the biggest challenge is energy
I understand what he's saying at the end. The people who will be replaced by AGI, are the people who don't know how to use it effectively.
Keep your quantum computing, but let’s fuck off with the AI
I fear that all the progress we could make, would be completely squandered by the powers that are greedy, manipulative and war hungry.
He might be a good physicists but it doesn't seems he knows much about computers. For example, he is calling encryption some digital technology. Also, being able to encryot won't automatically will give you access to any computer.
quantum computers will facilitate a look at quantum reality which occurs at a speed far faster than humans can ever achieve, let alone typically operate. this will help us realize how trivial most our thoughts are.
The only thing you can count on is that this will be used by the 1% to amass more wealth and power. Cause people are shit.
Wait till AL gets ahold of quantum computing..
This was disappointing. I love listening to MK talking about physics, but this video sounded like a pitch for investing in Quantum related stocks.
Quantum computers are the "forever on the verge of a breakthrough" technology. Been hearing about imminent quantum supremacy for the past 15 years. Quantum computers, assuming they will find a usable purpose, will never replace traditional computers simply because you can't have a quantum computer in your pocket.
All the big Quantum computing evangelists are in a way or another linked to the the same companies making the usual bold claims.
Wake me up when Quantum Marketing has actually something concrete and useful to show. Yawn…
it'd have to be able to catch a bullet from outerspace and tell ya about it.
Wise words and a merry tie. I anticipate a second more pressing need dealing with quantum computing. Energy demand for fusion, or new sources is needed to sustain the future. Tech needs energy.
Ai + quantum computer =🎉
Why we hide national securities? Quantum is everyone.
Post-quantum cryptography is here now and China passed “Q-Day” in spring 2025. Nobody is safe. The entire US government is required to convert to PQC by the end of 2026. The good doctor is not tracking the current state of play.
One day all the computers will take up all the energy and the average person will have no electricity, but they will still bow to the computer. It’s so stupid.
One day because of quantum computers the only thing you will have left to eat is your computer
Thank you for your service in Vietnam. A mistake of a war but you showed up when called upon.
Only 10 more years, right? Oh wait, no, that was nuclear fusion. 😂
This guy introduced me to big think. Thank you for being face of science after departure of Steven Hawking, Michio Kaku and Neil Degryse Tyson.
Even though both systems are computers, they will continue to perform two different types of tasks. It's like believing a cargo plane could replace a racing bicycle because both are technically means of transportation…
See Agri Dao to help agriculture efficiency.
How is there no threat of a meltdown if you are using metals when referring to the Fusion plant? The law of the conservation of matter rejects this possibility of free energy. There will be some form of waste that occurs from the production of that energy and the concern is how to best recycle or appropriately dispose of that waste if that is even possible, which we should hope is the case.
"Not just simultaneously, but simultaneously AT THE SAME TIME!".
I would be interested to hear him talk about A.I partnered with Quantum computing.
