That’s brilliant!!! My favourite definition of wealth

Religions with their numerous sects and countless explanations, are a good example of easily variable. This makes them immune to error correction because the interpretation on the texts varies from person to person. Compare to 3<1 or 2+2=4 which are invarable, regardless of if the contain errors. You cannot correct something if there is no way to test or detect for error.

A profoundly simple solution. Is a factor leading to the dismal of reason the intentional introduction of errors into communication to make error detection computationally more expensive? This makes reason seem ineffective, leading some to use cheaper, in the short term, methods. Mainly those arising from the older regions of the brain, capable of quick conclusions, but lacking almost any error correction.

Alright, I get it: your future self made you record this video 😂 The future is bright indeed, thank you 😊🎉

… a quest for comfort, wealth and power, more precisely. Which planet you’re living on?

Yes.. to experience something is to have it interprated to you - by your brain. Without that faculty there is obviously no experience.

Scientists famously don’t ever give an honest chance to anything substantially new. That’s why they’ve built the sarcophagi of mathematics around themselves:) You know they did but will never admit. Our natural human tendency to fail in explaining anything substantially is called: math. Don’t get me wrong: I was straight A from Math in university, and that subject made me able to finish my studies at all, make money and not to give up. It still does!

Great example of the headphones allowing a person to see without eyes. David eagleman did something similar in a TED talk, he used a.synaptic jacket to feel the crowd's cheering, and thus experiencing/interpreting their joy in real time 😂

Dead giveaway for an idiot is the phrase, “Science proved…”

I didn't quite understand much but I'd like an example. For instance, is the law of conservation of energy (LCE) a constraint to fundamental physics or not? Prof Deutsch at some point states that this can never be proven, since we can always come up with an exceptional situation, unforseen by our current theories. He gives the example of Pauli and the discovery of neutrinos to fix this exact disagreement of theory and observations. Another, the expansion of the universe seems to also happily contradict LCE. If LCE cannot be unconditionally trusted, how are we expected to know which transformations are allowed and which aren't "on the basis of our current fundamental theories"? In other words, apart from the philosophical insight about computations being a physical process, all the other stuff looks like a flawed circular argument. Might be wrong though. Maybe someone can show an actual non-trivial application of the theory.

why does it have to be more amazing

I mean, it proves SOME things. Like how if you mix some chemicals together, you set a fire, and why those things together set that fire. And realistically, since there is a definitive answer to all our science questions (even if we dont know it yet), science will eventually, given enough time, fully prove things

An example.... Gravity based universe, or magneto-plasma universe.

highlighting the physical identity of conversation and communication generators.

Free Palestine!!

Excellent 😊

Me: will you please just admit you're wrong Him:

Hey sir I really love your voice and knowledge, I will read your book in near as I am listening you I feel very much understanding physics

Hope your well Deutsch .. hope you succeed.. Take care

Very interesting

en.m.wikipedia.org/wiki/Woke How is that anti-enlightenment? Deutsch is critiquing the way reactionary forces characterise "woke" and yes probably how people who jump on bandwagons end up behaving. Btw he did the same mistake re. Brexit, believing people mean what they say, not seeing the hustle It is frustrating because his educational ideas "taking children seriously" are brilliant… and not in this spirit at all

Not a strong argument. Nazism advanced science faster in some areas _because_ they lacked moral restraint e.g regarding human experimentation on live subjects

The talk is called "What a Universal Constructor can and can't do" on the conference website. Maybe change title?

Why would an AGI have the same rights and freedoms as a person unless we assume it’s conscious?

Can someone help me understand the proof for the universal constructor David is speaking about here? I can’t quite wrap my head around it. 😅 From what I understand the classical laws of motion + initial condition worldview of physics can only account for necessary transformations, not for possible ones. David says according to constructor theory, there can be no fundamental theory of exact initial conditions. “The future is affected by knowledge we don’t have yet.” Therefore exact prediction of the future is impossible. In the same way exact prediction of the past is not possible, because knowledge of the past has been lost. On to the proof that universal constructor can exist. David say only finitely many kinds of objects that could be needed in constructions can possibly form spontaneously, i.e without knowledge. Everything complex either evolves in which case it can be made given the right knowledge or it can be made by a constructor, which can itself be made and so on to a chain of finite depth - using knowledge that can itself be created. Is David saying, that there is no law that would forbid a universal constructor to exist, which means it must be possible? I feel like I’m missing some key pieces 😅

I listen to everything DD says multiple times getting gold each time. Like he says in the Fabric of Reality. You can send knowledge on a journey of millions of light years and it can utterly transform its destination. His words on knowledge have transformed my view of reality utterly.

Tankyo bro lern me

David Deutsch is great! I'd love to hear him have a conversation with Iain McGilchrist

I love this guy :) I want to hear him talk to Iain McGilchrist and John Vervaeke

Mr Deutsch - my intellectual hero ! The chapter 'A physicists history of bad philosophy' from 'The Beginning of Infinity' should be a compulsory text for 1st year physics students'.

About knowledge that comes with no financial profit, power over others or, at the very least, substantial fame, no one will ever hear, regardless of it’s importance.

That does not mean half of number theory is not BS ! :)

Well put good sir. This ridiculous notion that placing guardrails on AGI will curtail it, or that there wont be bad actors and or nationstates that wouldnt continue towards supremacy with AGI. I say hands off the wheel lets see where this is going.

Key to success: - Define civilisation the way that makes you look civilised and, at the same time, pictures the ones using different definitions to be harmful, malicious dummies. So civilised, indeed!

Mathematics, in which I hold a straight A degree (for 34 years), is, indeed, the very essence of intellectualism and coincidentally, also the only source of every penny of profit ever made and every consequence that profit came with (the good, the bad and the ugly). It applies to all of our reality (to the ENTIRE universe) we chose to call discoverable. Similarly to Achilles who - due to the basic axioms of this made-up example - will never reach the turtle (since it always takes some time for him to get to it, and that time will always keeps the turtle ahead a tiny bit). Limitation that we introduce into any structure of assumed reality will limit the results we can possible gain while staying inside it. No, I’m not religious nor esoteric - not even limited in my scope of considerations.

Hopefully CT will help navigating toward the next frontier of understanding quantum gravity

There was a response on it from some woke guy. Why don't addressing it

When will this book be realsed. How to contact professor deutsch

Anti-intelectualism is everywhere and it sucks.

Without mathematical formulas and logic. The world as we know it today would not exist bottom line!

Top channel. Thanks.

Beautiful movie

😂

Thank you

When he says you can’t base political decisions on ’the Science’ what does he mean?

Witchcraft it’s a craft. You don’t know what your talking about . And I’m not joking. If you know you know. Fuq the internet

Understanding the universe around you is something that we can all do. But the nurture of your upbringing can and does affect your ability to get to the Truth. Because it can be difficult to drop the things that you have be taught to be true, but some ideas can not be proven. And therefore cannot be said to be true. So first observe the universe around you. Find something of interest, and ask How then Why. You can Guess the How and Why, but then you Must test your Guesses. But, If your results shows that your guesses were Wrong, Guess Again! Others should also test out your theory. You need to keep testing your theories, till you get to a point where you’re test results can show your hypothesis the most likely. This is the Scientific Method. There is no other way! The Truth depends on it. And it’s the because of the Scientific Method that you are reading this comment. 😊
