At 29:05 ...such a privilege, this current moment. Immediately wanted to catch a flight to Mass. There are many relevant questions that can be summed up illogically.

[@testosteronecivilization8819]

Hi, I would like to share with you my new article: The term hormone means impetus: a motivator for action. One might wonder what hormones-the biological mechanisms for intercellular signaling-have to do with artificial intelligence (AI). Well, first and foremost, it is human intelligence that creates this machine intelligence. AI is actually modelled after the neural networks that enable the cognitive ability of the human brain. However, our brain has evolved different layers in the hundreds of millions of years of evolution, and the neocortex, which is associated with our rational faculty of cognition, is a more recent development of our large mammalian brain. The neocortex is situated on top of previous layers of the limbic system that is responsible for stimulating and regulating our behavior. The motivation for our behavior is linked to survival through our ability to attain territory and resources, as well as sexual reproduction, which drives the organization of our society into a complex, adaptive social system.

Hey Lex, I'd love to hear a show about the vast influence of small and cabinet level Government institutions (Like the U.S. EEOC) influance on everyday Americans lives through legal precident and policy change. I'm a current Federal EEO Investigator in Los Angeles and would love to discuss it!

[@peterfirth7]

Lex, love your work. I am completely addicted to listening to you podcasts. I have a question, has anyone or is anyone working on the idea of merging HI and AI. Using AI to enhance the human and create a super intelligent human. If we struggle to replicate the human mind can we focus on an enhancement that might lead to replication.

But yea, when he was talking about how long it's been since he's played video games, and then I saw him look away from the screen the entire time the message telling him to ADS was on screen, I was like god damnit. He will probably go the rest of his life thinking that you can't aim guns in video games lol.

[@ayceeonethirty]

This has quickly become my favorite podcast. Always excited to see a new episode. EDIT: 15:25 is precisely why I said what I said. Too many podcasts try to force conversation to move at a certain pace, or get specific soundbites for youtube clips, and I just never see you do that with anyone. I'd rather you spend 20-30 minutes going into the abyss of an interesting topic than have that quickly sidelined to get to the "named segment we force in here every week".

I am used to watching Lex's interviews with popular science figures like Richard Dawkins, Leonard Suskind and such, but it is only after watching him interview someone in the field of AI that I can really appreciate how well versed he is in his own field. Not only are you one of the best interviewers I have seen in a while, but you also seem so knowledgeable in AI.

Its so refreshing that you have a variety of people on that arent on a constant tangent of covid discussions. Really helps pass the time. Thank you from the bottom of my heart 🤖🤘

[@chrisford7033]

I’d love to see you discuss inventory management solutions using machine learning, such as better forecasting, safety stock, optimization problems that feel like systems of equations waiting to be solved. I see companies impressed by a simple moving average inventory model that pre-stages raw materials to produce closer to the target window of the forecast based on known lead times and demand average to calculate cycle stock necessary and then taking a z-score times (in my situation) a static lead time standard deviation (7 weeks = .7) times the demand average to decide safety stock. There has to be an amazing way to do this via machine learning...

[@hardik114433]

We actually worked on this exact problem. Have a look at this papers from our lab 1. arxiv.org/abs/2006.04037 "Reinforcement Learning for Multi-Product Multi-Node Inventory Management in Supply Chains" 2. arxiv.org/abs/1910.00211 "Reinforcement Learning for Multi-Objective Optimization of Online Decisions in High-Dimensional Systems" 3. www.ifaamas.org/Proceedings/aamas2019/pdfs/p1802.pdf "Actor Based Simulation for Closed Loop Control of SupplyChain using Reinforcement Learning" 4. link.springer.com/chapter/10.1007/978-3-030-60843-9_3 "Reinforcement Learning of Supply Chain Control Policy Using Closed Loop Multi-agent Simulation" However, these kind of works are very difficult to publish and get through reviewers as most of them either underestimate the scale of problems or would play down algorithmic novelty.

[@expressionoffreedom7165]

I don't know what you precisely said, but it seems to me what we need to do is defragment society. I'm completely convinced the planet is a giant hard drive and nobody has taken the time to run a defragmentation on it. And now we have these wildly inefficient logistics and people competing in nonsensical ways.

[@expressionoffreedom7165]

Also the problem is your trying to forecast, and I think there needs to be an amazing way to preplan everything so there's no need to forecast. If your customers and their customers and so forth had a much better and more accurate plan, forecasts would have to be perfect.

I'd love to hear Lex's views (and others) on historical turning points and events that shape our ideas of the world today. More clear discussion is vital to our social health these days. And we should be having as many of those conversation as we can--while we still can openly have them. Someone mediating those conversations with a deliberate mind driven towards love, acceptance, and understanding is so incredibly valuable as well. So thank you.

[@josephhayes6071]

You do you Lex - I think we will all tune in for quality conversations, or a storytime format. Like a radio show in the great depression. Thanks dude, you're keeping me sane. I suggest War of the Worlds as a topic for your project.

[@TheRealStructurer]

Nice to listen to easy going conversation on such an important topic. Thanks for sharing 👍🏼

[@Deb.L.]

Mic - "I do believe in the power of social media to screw us up royally" Lex - "I don't shut up about love and I'm all about kindness, I now have many little mini armies of trolls" There, social media amplify, enable and accelerate ideas and things, we have the bad and the good in these platforms. Both come together, can't have one with out the other

[@Deb.L.]

@Iahi Ghusak Thanks to you, I took a look at the tfatk comments, many were very funny! Burst out laughing at a few of them. Lex is as sophisticated as he is guileless, there is this streak of stubborn naivety about him as a scientist - who is well versed in abstract thinking and capable of complex systems thinking - that is odd. I think many people can see this oddity. It's this contrast of traits that makes him interesting, oddly endearing to some and oddly off-putting to others!

Hi Lex, if you haven't seen the series Altered Carbon, much of what you and your guests philosophize around are highlighted in this movie.

Finally, allow me to finish by saying, keep up the terrific job, signed a fellow RL researcher

Lex, I really enjoy your podcast. I’ve been a huge fan of JRE for years and I see a lot of similarities with your show, but I appreciate the slight differences. Have you ever considered bringing someone onto your show that isn’t famous or well known? I think it would be really cool to hear you have a conversation with someone from the general public about the world, random topics, etc. Just a suggestion. I would do it, but if not me, I would like to see someone else. In any case, I love what you do and the message you’re spreading to the world. Love wins.

[@akhiljohnson6019]

[@_traphic]

@Lex yo, i just wanted to say that i really appreciate the fact read the comments and make it known. alot of times when i watch or read things on the internet & want to share my input, i dont, because most people of a certain status dont interact with their audience and i feel my input isnt heard or cared about. its a really cool thing when a content creator actually participates in their community, rather than just being someone to watch. it gives us, the viewers, a sense of belonging. we feel you actually care about us as people. we dont feel like another number, another view, another like, or a piece of your paycheck. i can confirm your idea, that there ARE alot of thoughtful, intelligent, kind people on these social platforms that dont speak because they dont feel included. i look forward to a day where these type of people are able to participate in healthy online discussion, even if its conflicting. thank you for being passionate and optimistic. if i feel this way, i know there are other people that feel the same, which means you are making an influence in a positive way. keep it up, bud. thanks again.

[@expressionoffreedom7165]

I think your only option is to make your own videos. In reality the comments are mostly a one-way street. They are after all called comments and not dialog. You are right it's nice to have said dialog, but I just don't think the KZbin comments are where it's at overall. I think that if you have unique input it probably is worth making your videos. I think the algorithm is pretty good at sorting the more unique stuff to the top. For instance, most of the rip-offs are usually ranked lower than the original. I'm not criticizing your comment. I think it's correct. I just don't think KZbin comments is always the healthiest location to express yourself.

[@_traphic]

@@expressionoffreedom7165 What i was saying is mostly a response to things said in the latest Joe Rogan interview w/ Lex which brought me here, to give you some context. I have all the equipment to have my own channel/podcast already, that i purchased for filming live music performances on my channel, Moshpit TV. Some of the stuff i got with plans for commentary & create from a personal platform, but there is some type of creative/motivational roadblock happening with me. im trying to figure myself out & spark my creative energy again. i definitely agree with you & recognize that my satisfaction for self expression could be better served in a different place. But i was more or less responding to the joe rogan piece specifically about conversation in comment sections & on twitter. you may ask why wouldnt i leave my comment on that video. the answer being that joe has said 1000x over again, he doesnt read the comments. so here, im speaking aimed at the other party in that convo, knowing there is a likelihood he will read it & that in itself makes me feel good.

Lex, please read up on Multilevel Security / Capability Based Security, it offers a way to have general purpose computing that is secure by default. Application programmers wouldn't have to worry about their bugs allowing a system to be corrupted, for example. Genode.org is working on a version that is moving towards the mainstream. Eros/KeyKos are historic systems that implemented it on mainframes. It would be a good topic for an interview if you can find the right guest.
