Aaronson is such an underrated speaker. Thanks for having him on again.

One of the few podcasts that always evokes a little spark of joy when I see a notification of a new episode. Would love to see Joscha Bach back soon.

Aaronson is such a great guy to interview. Smart, knowledgeable, and super reasonable. More of him, please!

"Life should not just be a journey to the grave with an intention of arriving safely in a well preserved body......." The intro is just thrilling 👏

Lex, thank you so much for this! We are an education establishment in the Republic of Sakha (Yakutia). We are helping school students to get the best education they can! We are waiting for you in our podcast! Please, press like, so Lex could see it! We would love to make this interview in the Russian language! The English is great as well, just saying.

"We should not fear the day when a CPU passes the turing test. The true day of concern is when the AI purposely fails." -Can't remember

Even tho I realize how much of an idiot I am every time I listen to your program...I love it. Don't stop.

I cant help but mimic this dude's smile while watching. Contagious

One of my favorite conversations. Awesome episode. I didn’t notice any sort of poor sound quality or rain noise in the beginning. Great as always. Thanks for making these.

i'm glad that ppl as established as Penrose aren't afraid to chase outlandish theories once in a while

Dear Lex, I have discovered you recently and I am impressed with your humbleness and great skills in taking interviews. Yesterday I had the privilege to listen to your father's interview and download his book on plasma, which I shared it with my dear friend Roger Spurr, the founder of Mudfossil University, and I felt it was amazing synchronicity when he told me he was just looking in depth into plasma at that time. He is a very well educated person in an array of fields from anatomy, physiology, molecular biology, chemistry, electricity, physics, anthropology, geology, religion, you will find yourself very challenged in taking his interview in just one session. He will blow your mind, and your mind will have to be very open to grasp the beyond textbooks levels of research, so I wish you good luck and a lot of interest in this subject. Most people will be overwhelmed but I am confident you will treat this with outmost seriousness and respect, based on your previous videos. I say that because I sense a great humbleness which is the attribute of extremely intelligent people. Yes, the more you know, the more you understand you know very little and there is much more to learn. So, I salute you and I admire you, and it would be a privilege if you would take my request seriously and look into it. You can contact me anytime, I will be delighted to make this interview possible. So please, take a few minutes to read this and check out Roger. I hope you'll make my dream come true. Blessings and lots of good vibes and love to you!

Compared to many recent interviewees his thoughts and answers are crystal clear. Just compare his answer about Penrose's model of consciousness .

Thank god got people like Scott that are smart enough to call bs on theories like Penrose’s that I could always could tell smelled funny.

Anyone craving a round 3 with Scott Aaranson hits like 👍

I thoroughly enjoyed this conversation. It made me ponder the words “immeasurable” and “value”, which came to mind as a result.

Thank you lex, this was a great episode. Even if I don't understand some of the complex topics I really enjoy listening to the passion that you and your guests have for the subjects. I'm inspired by every episode and I can't wait for more!

I agree with the knowledge you two find beautiful. I appreciate being able to be apart of witnessing this life. One of those things that make life worth living,god bless you both. Ty Scott and Lex. Another great podcast

Scott is the greatest guest. Fun, affable, down to earth, and wicked smaht

Simultaneously enjoying this and hating you for posting this after 1am as I was checking my subscription channels just before intending to close down my browser for the night.

One of the few podcasts that always evokes a little spark of joy when I see a notification of a new episode.

I'm glad these kind of topics are back. Lately, we were getting into down to earth topics like, what's your game plan when you are going to fight (physically) with someone, you're on top of your adversary and try to clamp him down ...I mean, i'm 56, i never had to fight anyone in all my life, and it's not because i always agree with everyone coming my way....thank you.

Great podcast. The rational line of thinking is actually very simple to follow, I appreciate the way Aaronson effectively delivers his points.

My favorite interview to date - touched all of my interests - nice job

Just looking at the topics it looks great. Can't wait to watch this one!

Watched it all, fascinating. Always nice to remind myself of things long forgotten, once read in a book 15 years ago! Btw, that drunken outro was something else!

Great discussion, Lex! You're the best..

Haven’t heard it yet but I’m glad to be back. Been depressed lately and need a good break.

Yasss Been Waiting for Round 2

thanks for the awesome podcasts! keep it up.

Hey Lex, is there any prospect of you interviewing Demis Hassabis ? Love the Podcast !

I really, really like the way this guy thinks and articulates himself. He's got a real knack for communication and lucid thinking. First person who's involved in anything quantum related that doesn't seem like they're selling me a bill of goods

Gosh who are you people here watching this, I want to befriend all of you. I am serious I want Lex's audience as friends, 0 people I know find Lex interesting, the people he brings and their discussions are boring for all the people I know, which I just want to repeat these discussions all day long. Lex PLEASE start a social media platform intended for your audience only I WANT TO BEFRIEND YOU PEOPLE ♥️💯 I finished listening, stop talking love start doing love, let's all come together on the LexBook/Fridder/instaman social media.

Thanks a lot for incredibly hard work youve put in this podcast . Thoughts that guests are saying so strongly relate to my own views that it helps a lot in these tumultuous times to percieve my self not like monster or freak or something. Спасибо еще раз большое ! Интервью Вашего отца тоже было очень глубокое и вдохновляющее.

Lex I love your work. It inspires me to get off my bum and do stuff.

Incredible conversation.

Brilliant interview!

I'd really love to see more depth on such topics! From what I can tell, you barely scratched the surface of computational complexity theory. As I see it, theoretical computer science/complexity theory is THE discipline that is ironically the most practical concerning questions about determinism, nondeterminism, consciousness and all those interesting concepts!

Keep up the great work @Lex!!!

Beautiful and I am very much looking forward to the next one.

Still one of my favorite episodes

Nice podcast. Thank you.

Lex, I highly recommend you to look into Bernardo Kastrup's work, and maybe interviewing him. His thoughts on the hard problem of consciousness are the most interesting that I've come across

love scott hes enthousiasm

great conversation.

awesome cast

I love listening to both of you

I wasn't expecting to like this podcast and I definitely didn't think I'd like Scott based on the way he spoke but yeah, he won my heart. I really enjoy him talking -- especially explaining the equation underlying quantum mechanics, I wish more people explained that equation. I have never been one for trying to understand history or people, in CS, when we'd get a history lesson over Djikstra before learning about his algos, I'd be like plllleaseeee just get to the algorithm already. But this was a refreshing perspective! Thanks Lex.

Awesome interview... Awesome interviewee...

When I heard question about computable universe I immediately thought of Penrose. Great job Lex, as always!

29:00 "ad nausium". He just slipped that in with a straight face. Nicely done.

As always - amazing! Thank you, Lex. All you need is love? Try to talk to Sir Paul McCartney - not Putin... Thanks to you and your guest Dr Aaronson! As you always saying - it was beautiful.

Thanks Lex

Lex, I'm sorry you got sweaty, but great podcast as always. I'm a big fan of yours, I've learned a lot from you. Thank you, sir.

Great interview. I wish you had one too with David Deutsch.

You rock Lex!

I keep thinking these interviews are showing me the smartest people I've ever witnessed and they just keep getting better.

He talks just like Ben Goertzel - both brilliant minds.

The raindrops are actually amazing

have used that hst quote before... it's a brilliant philosophy,

Bring him back for more. Awesome guest

Scott Aaronson is really a special scientist. More of him!

Hey Lex. Great stuff as usual. As a request, though I know it may be a bit much, could you link websites like Wikipedia for the high level concepts that are talked about or mentioned? It took me a bit long to find the AdS/CFT Correspondence, mostly due to messing up the speech to text, but I think it would be really cool to be able to purvey the theories and mathematical backings to the concepts that are talked about. Again, I know it would be a lot of extra work so no need to heed. Keep up the good work!

Thanks for the amazing content and exposure to so many different brilliant minds. Also conspiracies :*

Interesting to see this analysis 2 years later

Exceptional document ! Thanx to both of you, but WHAT IS THE DATE of the recording ? September 2020 ?

Lex, yet again, you've constructed a masterpiece. Great episode! Absolutely facinating.

Well done Lex, your humility only enhances your intelligence..

Nice video man

hey, good intro, made me smile!

Hey dude just subbed yesterday seen earlier video of your push up challenge, how did it go ? What changes did it make?

Hey Lex what mic is that? Can you tell us about the equipment you use for the podcast? Thanks.

cool way to learn a lot

I think you did a great job with the audio. The rain isn’t very noticeable, I thought it would be much worse from your intro.

Scott "you know" Aaronson in a house 😁😂 great conversation..made me think deep 😊

This is a VERY interesting podcast, I thoroughly enjoyed it! I am going to school to study neuroscience and psychology and consciousness and this put new ideas in my head. THANK YOU! and thank you Lex for not reading my IG message lol #Happyfan #Sadfan

These 2 are fantastic mhhm-ers. I'm 15 minutes in and I really like this guy.

In Penrose’s concluding remarks in ‘The Road to Reality’ he noted that not only do we currently not have the answer, but it’s most likely both very simple & standing right before our eyes. In an 2011 ‘Edge’ conversation, Deutsch pointed out that the exact ontology of ‘information’ is completely unknown, & that if & when we do figure it out we’ll almost surely be able to understand those deepest of deep ‘constructor’ laws that are even more foundational than quantum physics. ‘Thought’, ‘mind’, ‘intelligence’ & ‘consciousness’ are all information-related phenomena & as such it’s quite reasonable to assume that knowing information’s correct ontological identity - along with the role it fills here in our Universe - should be an especially useful aid in clarifying all of these directly information-related phenomena. And such is the case. And the principal reason we haven’t been able to determine the ontological identity of any of these directly information-related phenomena to date is simply due to the fact that we’ve fallen into the habit of considering ‘digits’ to be ‘information’ but ‘digits’ are not ‘information’ no matter how many of these particular entities one has at one’s disposal, nor how cleverly arranged they are, nor how massively miniaturised they are in their orchestrated dance around on the surface of the many tiny chips on which they do so customarily dance inside our computers & communicating devices, nor, indeed, how large, powerful & globally interconnected are the machines & devices, systems & gadgets operating on them. Mind you real information can be turned into digits, & can be trundled through any dedicated digit-using machine in digital form - but no such dedicated digit-using machine can ‘think’ - or be conscious, or intelligent. (See my concluding comments below)

Welcome to Austin, Lex. You're going to like it here.

Is that an ironing-board / table I see in the background? Probably not but I'm totally down with it.

Good video

Fantastic

I enjoy your podcast. Please keep doing what you are doing, let your intuition guide you. Enjoy Austin! Utilizing social media platforms is great on getting traction, but it’s sad to hear that you are affected by mean comments and trolls, or annoyed by some comments. It seems so stressful. Sending ❤️ May all beings be struggling beautifully? May all beings find a small happiness and peace to keep them going. I listen to this podcast because I always curious with consciousness and the universe. I don’t have a strong background in mathematics, physics, CS or AI, so I may miss important points in this discussion. This is a layman perspective on how my brain works. Initially, I thought there’s a mysterious force that guide the flow of understanding. For instance, I read a paper let say 2 or 3 years ago, but it’s only now I truly understand it that I read it again, having read another related papers. Maybe there was some kind of illusions of competence that prevent me to get new insight. Anyway, because I thought it’s mysterious, I know that it’s stupid, but I become heavily rely on waiting for “the mysterious guidance” or “the right time” to write the discussion of my research findings. I learned the hard way, I never finished my dissertation. People think that I’m aiming for a perfect dissertation, but actually I just want it to be a solid research and useful, not merely adding more data or confirmation, although it’s still very important to do that. So, I’m waiting for the mysterious force to let me find a complete understanding or I procrastinate, I become a big procrastinator. After I read a book entitled “a mind for numbers” by Barbara Oakley, I found that it’s not a mysterious force, my brain just go into “diffuse-mode”, so sometimes idea came when I was not working on my writing. But, it’s impossible to find new knowledge according to the book without building a library of knowledge, the key is to enrich my reading sources instead of waiting for an idea to come. It takes time for the brain to build new synapses. Since I’m a slow learner, it may take more time for my brain to build new network to understand new knowledge. Or in AI term, adding a new algorithm? Sir Roger Penrose argued that the way computers run an algorithm and do computation is different from the way we understand an algorithm. And I also think that computers can only regurgitate any information loaded into its program, it can’t acquire outside sources, so how can it correct its error? My brain is constantly changing what it believes, through understanding. I wonder how a super AI corrects the bugs by itself? I watched a movie, serenity, in the movie everyone who lives in a simulation has limited access. It makes me think that maybe I’m living in a simulation, because sometimes I can predict future events in my dreams, usually it’s a symbol not actual events. But of course, it’s not 100% accurate, so let’s dismiss it. I don’t have any experience or enough knowledge on speculating that we’re living in a simulation, guided by complex algorithms.

You can absolutely establish the fact of the simulation from its errors once you know what to look for. I see them all the time now, mostly in the execution of relationships that come under regular scrutiny for certain reasons.

In order to follow along in this interview, I need to marshal my entire consciousness

Bring this guy N more times please

Hey Lex love what you are doing! It would be helpful for me to have additional resources about the material discussed, so I could find out more and dive deeper into the concepts. Thanks if you ever find your way to this comment:)

haha I love the intro.

Another banger

I didn't understand all questions and answers, but I REALLY understand that Lex "knows"

Lex Fridman's conversation with Bruce Banner was absolutely fascinating

Hi lex, wouls it be possible to get on scientists who reject the worldview of materialism?

With the lookup table then remove the table and casually either remove data and then to form conclusions that the table didn’t necessarily look up however rather thought of.

Great interview! You should invite Michael Graziano on sometime. He’s got an interesting theory of consciousness - attention schema theory. Think it would be a very interesting conversation between you two.

Oh what a good day !!!

I could listen to Scott talk about quantum mechanics and consciousness philosophy forever. If I was rich, and he were willing, I'd pay him to follow me around and just talk to me about stuff.

Finally a reality check from a computer scientist on consciousness. How refreshing.

@Lex Fridman What would you suggest? A formal education on AI/Deep learning like a Master’s degree and PHD or self learning and exploration given that there is equal determination and obligation in both cases. The end goal is to innovate in the area of AI/Deep learning and do something that gives me satisfaction of creativity. Thanks in advance.

We need a podcast with the "Physics Videos by Eugene Khutoryansky" guy, or if it's happened already, someone please link it, thanks

Great podcast! Would love to see Linus Torvalds in your podcast.
