Is there a transcript somewhere? (It's 2 hours 9 minutes)

There's a youtube generated one if you go to https://www.youtube.com/watch?v=-EVqrDlAqYo and click the three dots under the vid.

I don't know if there's a way to get those things into an easy to read format? Clicking select all and pasting to the text editor sort of works but could be better.

AI is a choice (that is, it can probably be ignored, if we don't like it). I'm not sure why people think (negative forms of) AI are in some way inevitable. A lot of people are already afraid of losing their jobs right now, where we can't even fathom the basics of intelligence. I don't think humanity would just let some of the negative forms of AI we all seem so afraid of happen.

"I don't think humanity would just let some of the negative forms of AI we all seem so afraid of happen." Government and corporations are the ones who will make that call. Government = Wolf Corporation = Fox Average Joe = Sheep Most of the sheep are protected by a cage; it takes a lot of mental power to operate in the increasingly technical world we've created. Solve AI and you've removed that cage. Sure we'll still…

Governments and corporations are nothing without your Average Joe, in fact, they are just a collection of Average Joes. So I fail to see the analogy here.

Been following hawkins and Numenta for a while. They have never really taken off in commercial applications as far as I know despite some sound reasoning behind their theories. Hopefully they will make an impactful breakthrough soon.

same, I have been following before they changed the name to Numenta. Interesting stuff, will listen to this podcast soon

Once intelligence is "solved", most humans are completely and utterly screwed.

There's the "Wally vs. Star Trek" theory of Artificial Intelligence (I know it sounds goofy, but it makes a difference when looking towards the direction of AI). If you look at the direction AI will take, science fiction is really all we have to go on and we have three platforms: Terminator - To be avoided at all costs (everyone agrees) Wally - AI does its best to "take care" of us, turning us into infantile, unthink…

How about the Culture option - AI is as far beyond us as we are beyond our pets, and takes care of us accordingly. But just like you don't stick your dog in a box and feed it morphine continuously, AI doesn't turn us into "infantile, unthinking, pleasure seeking dweebs" either.

> While intelligent behaviours appear to reside in the cortex, the limbic system is heavily involved in learning and cognition generally. We understand the limbic system to process motivation and emotion; could the limbic system's activation during cognition not be "explained away" by it being recruited to process the emotional or motivational aspects of sensory or memory data? (Just like how there is visual cortex r…

You're ignoring a lot of its function. The hippocampus (within the limbic system) is necessary for long-term memory. If your hippocampi are removed, you still act more of less the same, but you can't remember new events or make semantic memories. Attention is also an important function of the limbic system.

The famous case is that of Henry Molaison (HM): https://en.wikipedia.org/wiki/Henry_Molaison

In this situation, heads of state and corporate executives are as much 'Average Joes' as kings and queens were a few centuries ago.

Learning a lot about the neocortex. Any recommendations on how to learn more? @7:45 It’s the size of a dinner napkin, 2.5mm think, uniform, and similar in other animals. @9:50 if you took the optic nerve and attached it to another part of the neocortex, that part would become the visual region. @34:30 Thousand brains theory of intelligence.

> if you took the optic nerve and attached it to another part of the neocortex, that part would become the visual region.

FYI, that is super hand-wavey and covers over a lot about how the path of the information from the cones/rods gets into V1. The chain of neurons that pass infomation from your eyes to V1 is well studied [0]. Interruptions in that path cause a lot of sightedness issues and are not fun diseases to have. The musician, Stevie Wonder, among others, aledgedly has a form of blindness known as blindsight [1] where relfexes to motion are perserved, but information is not passed into the conscious mind.

In the end, though neuroscience is a facinating subject, we're just in the beginning of our understanding of the brain. More research is needed.

[0] https://en.wikipedia.org/wiki/Optic_chiasm a good place to start learning about the chain of information transfer.

EDIT: Additionally, if you want to learn more about neuroscience, the best place to look is at Kandel's Principals of Neural Science [2]. It is a tome of a book, but is the best place to get a deep dive into the brain and our understanding of it. I've not yet seen anything else that is somewhat accessible to the general public but also gets into all the issues with any particular experiment. Most pop-sci book brush over a lot of the very important and thorny issues that each experiment has. I'd also love to know of a good book that is more accessible than Kandel.

Tech is not a choice, especially when there are evident benefits from the tech. Like for instance was agriculture a choice, yes maybe for a small while after it was invented. After that it was no longer a choice. Now it's not a choice at all. AI will be much quicker.

Tech is most definitely optional: Nuclear energy was for a while considered a great option, but now a lot of people are (unfairly IMO) turning their back on it, and you see that there isn't as significant a number of new plants built (just to give an example)

It's worth noting that the Wally and Star Trek interpretations are not incompatible. What are the trillions of people that can't qualify to be a red shirt doing? Probably zonked out in a holodeck

Cavorting in SF, bottling wine, or occasionally taking classic muscle cars out for a spin apparently.

Yes, but a government and a corporation is much more than their head of state and corporate executive. If the actions of the government have a significant negative effect on a majority of the population, you can be quite sure that the government will be overturned at some point.
